A major nerve of the upper extremity. The fibers of the musculocutaneous nerve originate in the lower cervical spinal cord (usually C5 to C7), travel via the lateral cord of the brachial plexus, and supply sensory and motor innervation to the upper arm, elbow, and forearm.
The large network of nerve fibers which distributes the innervation of the upper extremity. The brachial plexus extends from the neck into the axilla. In humans, the nerves of the plexus usually originate from the lower cervical and the first thoracic spinal cord segments (C5-C8 and T1), but variations are not uncommon.
Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.
A dead body, usually a human body.
A long flat muscle that extends along the whole length of both sides of the abdomen. It flexes the vertebral column, particularly the lumbar portion; it also tenses the anterior abdominal wall and assists in compressing the abdominal contents. It is frequently the site of hematomas. In reconstructive surgery it is often used for the creation of myocutaneous flaps. (From Gray's Anatomy, 30th American ed, p491)
A major nerve of the upper extremity. In humans the fibers of the radial nerve originate in the lower cervical and upper thoracic spinal cord (usually C5 to T1), travel via the posterior cord of the brachial plexus, and supply motor innervation to extensor muscles of the arm and cutaneous sensory fibers to extensor regions of the arm and hand.
A plant species of the family CLUSIACEAE. The common name of 'Bitter Kola' is sometimes also used to refer to COLA.
Phenanthrenes are aromatic hydrocarbons consisting of three benzene rings fused together in a linear arrangement, commonly found in various plants and some animals, and can act as precursors for certain steroid hormones or exhibit pharmacological activities with potential therapeutic uses.

Surgical treatment of compression of the lateral antebrachial cutaneous nerve. (1/27)

We describe an operation to relieve compression of the lateral antebrachial cutaneous nerve at the elbow. Between 1987 and 1997 we operated on seven patients, one with bilateral compression. In two the compression was associated with injury to biceps. A longitudinal or a transverse incision was carried out and the nerve was released from the deep fascia. Partial excision of the biceps aponeurosis was undertaken in the patients who did not have injury to biceps; some additional procedures were required for those patients with injuries. All patients had symptomatic relief.  (+info)

The musculocutaneous nerve. (2/27)

We have analysed the results of repair of traumatic lesions of the musculocutaneous nerve in 85 patients, which were graded by Seddon's modification of the Medical Research Council system into three types of injury: open 'tidy', open 'untidy' and closed 'traction'. They were also correlated with associated arterial injury. There were 57 good, 17 fair and 11 poor results. The type of injury was the most important factor in determining the result; 12 of 13 open-tidy lesions gave good results compared with 30 of 48 closed-traction lesions. The results were better when the nerves were repaired within 14 days of injury and when grafts were less than 10 cm long. They were worse in the presence of associated arterial or bony injury.  (+info)

A variation of the musculocutaneous nerve absent. (3/27)

A variation of the brachial plexus, characterized by the absence of the musculocutaneous nerve on the left arm, was found during the dissection of a 28-year old male cadaver. The whole lateral cord was joined to the median nerve, which it met in two points. One was a typical junction of both roots of the median nerve at the level of the coracoid process. The other was a junction of the remaining lateral cord and the median nerve, which was 92 mm away from the typical junction. This case provided some evidence about the absence of the musculocutaneous nerve, rather than a complete fusion of the median and musculocutaneous nerves. As the nerves are named due to their course or innervation, and not from their origin, it is reasonable to assume that the combined nerve was actually the median nerve, and that the musculocutaneous nerve did not exist.  (+info)

The transition from development to motor control function in the corticospinal system. (4/27)

During early postnatal development, corticospinal (CS) system stimulation, electrical or transcranial magnetic, is minimally effective in producing muscle contraction, despite having axon terminals that excite spinal neurons. Later, after stimulation becomes more effective, the cortical motor representation develops, and movements the system controls in maturity are expressed. We determined whether development of temporal facilitation (response enhancement produced by the second of a pair of pyramidal tract stimuli, or a higher stimulus multiple of a train of stimuli) correlated with these changes. Facilitation of the monosynaptic CS response was larger in older kittens and adults than younger kittens. When facilitation was strong, strong motor responses were evoked by pyramidal stimulation with small currents and few pulses. With strong facilitation in older kittens, corticospinal axon varicosities colocalize synaptophysin like adults, suggesting a presynaptic mechanism. With effective facilitation, control signals from the cortex can be sufficiently effective to provoke muscle contraction for guiding movements.  (+info)

Changes in spinal cord architecture after brachial plexus injury in the newborn. (5/27)

Obstetric brachial plexus palsy is a devastating birth injury. While many children recover spontaneously, 20-25% are left with a permanent impairment of the affected limb. So far, concepts of pathology and recovery have focused on the injury of the peripheral nerve. Proximal nerve injury at birth, however, leads to massive injury-induced motoneuron loss in corresponding motoneuron pools and therefore limits the extent of functional recovery. In the present study, the role of spinal cord plasticity after injury and recovery from obstetric brachial plexus lesions was investigated. A selective injury to spinal roots C5 and C6 was induced in newborn Sprague-Dawley rats, leading to motoneuron loss in corresponding motoneuron pools. Recovery of extremity function was evaluated with different behavioural paradigms. Permanent changes of adjacent motoneuron pools were quantitatively evaluated by retrograde tracing and functional muscle testing. We report that the adjacent C7 motoneuron contribution to biceps muscle innervation increased four-fold after upper trunk lesions in newborns, thus compensating for the injury-induced motoneuron loss. These results indicate that, in obstetric brachial plexus palsy, changes in spinal cord architecture are an integral part not only of primary pathology but also of the subsequent recovery process. While present treatment is directed towards the restoration of neural continuity, future treatment strategies must recognize and take advantage of CNS participation in the injury and recovery process.  (+info)

Tick paralysis with atypical presentation: isolated, reversible involvement of the upper trunk of brachial plexus. (6/27)

Tick paralysis is a disease that occurs worldwide. It is a relatively rare but potentially fatal condition. The only way to establish the diagnosis is to carefully search for the tick paralysis. It is caused by a neurotoxin secreted by engorged female ticks. Tick paralysis generally begins in the lower extremities and ascends symmetrically to involve the trunk, upper extremities and head within a few hours. Although early-onset prominent bulbar palsy and isolated facial weakness without generalised paralysis are rare, there is no report in the English literature concerning isolated, reversible involvement of the upper trunk of brachial plexus caused by tick bite. We report a case of isolated, reversible involvement of the upper trunk of brachial plexus as a variant of tick paralysis. Diagnosis was confirmed with needle electromyography and nerve conduction examination. Within 2 weeks, the patient was fully recovered. The purpose of presenting this case is to remind clinicians that tick paralysis should be considered even in cases with atypical neurological findings admitted to the emergency department.  (+info)

An anatomical study of the subcoracoid space. (7/27)

PURPOSE: To evaluate the amplitude of the subcoracoid space under maximum internal and external rotations of the humeral head and measure the distance between the apex of the coracoid process and the following anatomical structures: (a) point of entry of the musculocutaneous nerve and its branches into the coracobrachial muscles and into the short head of the biceps brachii muscle; (b) acromial artery; (c) lesser tubercle of the humerus. METHOD: Thirty shoulders of fresh cadavers, without any kind of shoulder pathology, (9 males and 6 females) were dissected, and the distances (in mm) were measured between the anatomical structures defined above and the apex of the coracoid process. RESULTS: The mean distance between the apex of the coracoid process and the musculocutaneous nerve was 49.2 mm (in all specimens a proximal branch of the nerve was identified 34.2 mm away from the apex of the coracoid process), which was not significantly different between the sexes or body sides; the mean distance between the apex of the coracoid process and the acromial artery was 12.4 mm, which was not significantly different between the sexes or body sides; the mean distance between the apex of the coracoid process and the lesser tubercle of the humerus, with the humeral head under internal rotation, was 10.6 mm in men and 8.6 mm in women, values that were significantly different between the sexes. DISCUSSION: In women, the smaller distance between the apex of the coracoid process and the lesser tubercle of the humerus in the arm internal rotation suggests a higher chance of impingement between those bone structures among the female sex.  (+info)

Repair of brachial plexus lower trunk injury by transferring brachialis muscle branch of musculocutaneous nerve: anatomic feasibility and clinical trials. (8/27)

BACKGROUND: There are few effective methods for treating injuries to the lower trunk of brachial plexus, and the curative effect is usually poor. The purpose of this study was to provide anatomic references for transferring the brachialis muscle branch of musculocutaneous nerve (BMBMCN) for selective neurotization of finger flexion in brachial plexus lower trunk injury, and to evaluate its clinical curative effects. METHODS: Microanatomy and measurement were done on 50 limbs from 25 adult human cadavers to observe the origin, branch, type of the BMBMCN and median nerve, as well as their adjacent structures. Internal topographic features of the fascicular groups of the median nerve at the level of the BMBMCN were observed. In addition, the technique of BMBMCN transfer for selective neurotization of finger flexion of the median nerve was designed and tested in 6 fresh adult human cadavers. Acetylcholinesterase (AchE) staining of the BMBMCN and median nerve was done to observe the features of the nerve fibers. This technique was clinically tried to restore digital flexion in 6 cases of adult brachial plexus lower trunk injury. These cases were followed up for 3, 6, 9 and 12 months postoperatively. Recovery of function, grip strength, nerve electrophysiology and muscle power of the affected limbs were observed and measured. RESULTS: The brachialis muscle was totally innervated by the musculocutaneous nerve (MCN). Based on the Hunter's line, the level of the origin of the BMBMCN was (13.18 +/- 2.77) cm. AchE histochemical staining indicated that the BMBMCN were totally made up of medullated nerve fibers. At the level of the BMBMCN, the median nerve consistently collected into three fascicular groups as shown by microanatomy in combination with AchE stain. The posterior fascicular group was mainly composed of anterior interosseous nerves and branches to the palmaris longus. The technique was tested in six fresh cadavers successfully, except that stoma split occurred in one case. Five of the six cases recovered digital flexion 12 months after operation, and at the same time grip strength, muscle power, and nerve electrophysiology also recovered markedly. CONCLUSIONS: The technique of transferring the BMBMCN for selective neurotization of finger flexion is anatomically safe and effective, with satisfactory clinical outcomes.  (+info)

The musculocutaneous nerve is a peripheral nerve that originates from the lateral cord of the brachial plexus, composed of contributions from the ventral rami of spinal nerves C5-C7. It provides motor innervation to the muscles in the anterior compartment of the upper arm: the coracobrachialis, biceps brachii, and brachialis. Additionally, it gives rise to the lateral antebrachial cutaneous nerve, which supplies sensory innervation to the skin on the lateral aspect of the forearm.

The brachial plexus is a network of nerves that originates from the spinal cord in the neck region and supplies motor and sensory innervation to the upper limb. It is formed by the ventral rami (branches) of the lower four cervical nerves (C5-C8) and the first thoracic nerve (T1). In some cases, contributions from C4 and T2 may also be included.

The brachial plexus nerves exit the intervertebral foramen, pass through the neck, and travel down the upper chest before branching out to form major peripheral nerves of the upper limb. These include the axillary, radial, musculocutaneous, median, and ulnar nerves, which further innervate specific muscles and sensory areas in the arm, forearm, and hand.

Damage to the brachial plexus can result in various neurological deficits, such as weakness or paralysis of the upper limb, numbness, or loss of sensation in the affected area, depending on the severity and location of the injury.

A nerve transfer is a surgical procedure where a functioning nerve is connected to an injured nerve to restore movement, sensation or function. The functioning nerve, called the donor nerve, usually comes from another less critical location in the body and has spare nerve fibers that can be used to reinnervate the injured nerve, called the recipient nerve.

During the procedure, a small section of the donor nerve is carefully dissected and prepared for transfer. The recipient nerve is also prepared by removing any damaged or non-functioning portions. The two ends are then connected using microsurgical techniques under a microscope. Over time, the nerve fibers from the donor nerve grow along the recipient nerve and reinnervate the muscles or sensory structures that were previously innervated by the injured nerve.

Nerve transfers can be used to treat various types of nerve injuries, including brachial plexus injuries, facial nerve palsy, and peripheral nerve injuries. The goal of the procedure is to restore function as quickly and efficiently as possible, allowing for a faster recovery and improved quality of life for the patient.

A surgical flap is a specialized type of surgical procedure where a section of living tissue (including skin, fat, muscle, and/or blood vessels) is lifted from its original site and moved to another location, while still maintaining a blood supply through its attached pedicle. This technique allows the surgeon to cover and reconstruct defects or wounds that cannot be closed easily with simple suturing or stapling.

Surgical flaps can be classified based on their vascularity, type of tissue involved, or method of transfer. The choice of using a specific type of surgical flap depends on the location and size of the defect, the patient's overall health, and the surgeon's expertise. Some common types of surgical flaps include:

1. Random-pattern flaps: These flaps are based on random blood vessels within the tissue and are typically used for smaller defects in areas with good vascularity, such as the face or scalp.
2. Axial pattern flaps: These flaps are designed based on a known major blood vessel and its branches, allowing them to cover larger defects or reach distant sites. Examples include the radial forearm flap and the anterolateral thigh flap.
3. Local flaps: These flaps involve tissue adjacent to the wound and can be further classified into advancement, rotation, transposition, and interpolation flaps based on their movement and orientation.
4. Distant flaps: These flaps are harvested from a distant site and then transferred to the defect after being tunneled beneath the skin or through a separate incision. Examples include the groin flap and the latissimus dorsi flap.
5. Free flaps: In these flaps, the tissue is completely detached from its original blood supply and then reattached at the new site using microvascular surgical techniques. This allows for greater flexibility in terms of reach and placement but requires specialized expertise and equipment.

Surgical flaps play a crucial role in reconstructive surgery, helping to restore form and function after trauma, tumor removal, or other conditions that result in tissue loss.

A cadaver is a deceased body that is used for medical research or education. In the field of medicine, cadavers are often used in anatomy lessons, surgical training, and other forms of medical research. The use of cadavers allows medical professionals to gain a deeper understanding of the human body and its various systems without causing harm to living subjects. Cadavers may be donated to medical schools or obtained through other means, such as through consent of the deceased or their next of kin. It is important to handle and treat cadavers with respect and dignity, as they were once living individuals who deserve to be treated with care even in death.

The rectus abdominis is a paired, flat, and long muscle in the anterior (front) wall of the abdomen. It runs from the pubic symphysis (the joint where the two pubic bones meet in the front of the pelvis) to the xiphoid process (the lower end of the sternum or breastbone) and costal cartilages of the fifth, sixth, and seventh ribs.

The rectus abdominis is responsible for flexing the lumbar spine (lower back), which helps in bending forward or sitting up from a lying down position. It also contributes to maintaining proper posture and stabilizing the pelvis and spine. The muscle's visibility, especially in its lower portion, is often associated with a "six-pack" appearance in well-trained individuals.

The Radial nerve is a major peripheral nerve in the human body that originates from the brachial plexus, which is a network of nerves formed by the union of the ventral rami (anterior divisions) of spinal nerves C5-T1. The radial nerve provides motor function to extensor muscles of the upper limb and sensation to parts of the skin on the back of the arm, forearm, and hand.

More specifically, the radial nerve supplies motor innervation to:

* Extensor muscles of the shoulder (e.g., teres minor, infraspinatus)
* Rotator cuff muscles
* Elbow joint stabilizers (e.g., lateral head of the triceps)
* Extensors of the wrist, fingers, and thumb

The radial nerve also provides sensory innervation to:

* Posterior aspect of the upper arm (from the lower third of the humerus to the elbow)
* Lateral forearm (from the lateral epicondyle of the humerus to the wrist)
* Dorsum of the hand (skin over the radial side of the dorsum, including the first web space)

Damage or injury to the radial nerve may result in various symptoms, such as weakness or paralysis of the extensor muscles, numbness or tingling sensations in the affected areas, and difficulty with extension movements of the wrist, fingers, and thumb. Common causes of radial nerve injuries include fractures of the humerus bone, compression during sleep or prolonged pressure on the nerve (e.g., from crutches), and entrapment syndromes like radial tunnel syndrome.

Garcinia kola, also known as bitter kola, is not a medical term but a botanical name of a plant species that has been used in traditional medicine. It belongs to the family Guttiferae and is found in tropical rainforests of Africa. The nuts of this plant have been used in folk medicine for treating various conditions such as liver diseases, malaria, throat infections, and fever. However, it's essential to note that while some studies suggest potential health benefits, more research is needed before any medical claims can be made. It's always recommended to consult with a healthcare professional before starting any new supplement or treatment.

Phenanthrenes are not typically defined in a medical context, but they are a class of organic compounds that have a polycyclic aromatic hydrocarbon structure consisting of three benzene rings fused together. They can be found in some natural products and have been studied for their potential pharmacological properties. Some phenanthrenes have shown anti-inflammatory, antioxidant, and cytotoxic activities, among others. However, more research is needed to fully understand their therapeutic potential and safety profile.

Pancreaticojejunostomy is a surgical procedure that involves connecting the pancreas to a portion of the small intestine called the jejunum. This connection is typically created after the head of the pancreas has been removed, as in the case of a pancreaticoduodenectomy (or "Whipple") procedure. The purpose of this anastomosis is to allow digestive enzymes from the pancreas to flow into the small intestine, where they can aid in the digestion of food.

The connection between the pancreas and jejunum can be created using several different techniques, including a hand-sewn anastomosis or a stapled anastomosis. The choice of technique may depend on various factors, such as the patient's individual anatomy, the surgeon's preference, and the reason for the surgery.

Pancreaticojejunostomy is a complex surgical procedure that requires significant skill and expertise to perform. It carries risks such as leakage of pancreatic enzymes into the abdominal cavity, which can lead to serious complications such as infection, bleeding, or even organ failure. As such, it is typically performed by experienced surgeons in specialized medical centers.

"Cola" is not a medical term. It is a type of flavored carbonated soft drink that originated in the United States. The term "cola" comes from the name of the kola nut, which contains caffeine and has been used as a flavoring ingredient in these drinks. There are many brands of cola, but the two most well-known are Coca-Cola and Pepsi-Cola.

Colas typically contain carbonated water, high fructose corn syrup or sugar, caramel color, phosphoric acid, natural flavors (including extracts of the kola nut), and sometimes caffeine. Some people may use the term "cola" to refer specifically to Coca-Cola or Pepsi-Cola, while others may use it as a generic term for any type of cola-flavored soft drink.

While colas are widely consumed around the world, they have been associated with certain health concerns due to their high sugar content and other ingredients. For example, excessive consumption of colas has been linked to obesity, tooth decay, and bone density loss. However, it's important to note that these risks can be mitigated by consuming colas in moderation and maintaining a balanced diet.

Aphrodisiacs are substances that are believed to stimulate sexual desire or increase sexual pleasure. They can come in various forms, including foods, drinks, and medications. Some claimed aphrodisiacs include oysters, chocolate, certain herbs like ginseng and gingko biloba, as well as drugs such as Viagra. However, it's important to note that the effectiveness of most aphrodisiacs is not supported by scientific evidence, and some may even have harmful side effects if misused or taken in large quantities.

It's always recommended to consult with a healthcare professional before taking any substances for sexual purposes.

Biflavonoids are a type of flavonoid, which are plant-based compounds with antioxidant properties. Biflavonoids are unique because they consist of two flavonoid molecules joined together. They can be found in various plants, including fruits, vegetables, and herbs. Some research suggests that biflavonoids may have potential health benefits, such as reducing inflammation and protecting against oxidative stress. However, more research is needed to confirm these effects and determine the optimal dosages for human consumption.
