Shoulder4
- Interscalene nerve block is typically performed to provide anesthesia or analgesia for surgery of the shoulder and upper arm. (medscape.com)
- CONCLUSION: Sprengel's deformity is a rare congenital shoulder deformity, and the Woodward procedure could cause nerve injury in patients with severe Sprengel's deformity. (bvsalud.org)
- Intraoperative neuromonitoring (IONM) is widely used for detecting emerging spinal cord or peripheral nerve injury during spinal and shoulder surgery. (bvsalud.org)
- Four months after initial assessment, we repeated the syndrome, and 1 had scapular winging and shoulder neurologic examinations, and patients or family members abduction weakness consistent with a long thoracic nerve completed a self-administered questionnaire that gathered paralysis. (cdc.gov)
Autonomic1
- Depending on its pathogenesis, spinal cord disease can manifest with variable impairment of motor, sensory, or autonomic function. (medscape.com)
Branches4
- The branches from the cords go to form the terminal nerves of the upper extremity, namely the musculocutaneous, axillary, median,radial, and ulnar nerves. (asra.com)
- The cords continue distally to form the 'branches', which are the 5 main nerves of the upper limb. (pondermed.com)
- Caption = Areas of distribution of the cutaneous branches of the posterior divisions of the spinal nerves. (en-academic.com)
- The inferior alveolar nerve (from CN V3) runs in the mandibular canal, giving off branches to the lower teeth and gingivae as it passes. (unboundmedicine.com)
Posterior1
- The posterior cord divides and forms the radial nerve and the axillary nerve . (pondermed.com)
Connective tissue sheath1
- The dorsal root sleeve contains the dorsal root ganglion near the point at which both sleeves merge to become the connective tissue sheath (perineurium) of a spinal nerve. (neupsykey.com)
Foramen magnum2
- The spinal cord starts superiorly at the level of the foramen magnum and terminates inferiorly at the conus medullaris. (learnsurgeryonline.com)
- As well as some malformations at the occipital level, foramen magnum and some ducts where cranial nerves run. (atlasprofilax.la)
Nervous system3
- Neuropathic pain is caused by abnormal nerve signalling in the nervous system and, as a result, commonly does not respond to most pain relief strategies. (myvmc.com)
- For example, the nerves that supply the fingers exit the central nervous system at one level of the spinal cord, and the nerves that supply the toes exit at a different level. (myvmc.com)
- Overall, the intricate structure of nerves allows for the efficient transmission of electrical signals across the body, facilitating communication between different parts of the nervous system and enabling sensory perception, motor control, and coordination of bodily functions. (bioguideline.com)
Ulnar1
- The medial cord becomes the ulnar nerve . (pondermed.com)
Somatic system1
- Most of the cranial nerves belong to the somatic system. (byjus.com)
Body's1
- The body's spinal column enables each of us to walk upright. (ceufast.com)
Sympathetic2
- A sympathetic nerve to the heart that carries impulses that speed the heart rate. (unboundmedicine.com)
- This produces unilateral, segmental, somatic, and sympathetic nerve blockade, which is effective for anesthesia and in treating acute and chronic pain of unilateral origin from the chest and abdomen. (who.int)
Canal5
- A small opening where the nerves leave the spinal canal. (piedmont.org)
- In order to access the spinal canal, spinal cord, or the nerves coming from the cord through intricately designed foramen, the doors of the lamina must be breached. (ceufast.com)
- complete breech - occurs when the baby's knees are bent and the feet are close to the rear, which is positioned to emerge first from the birth canal. (chaliklaw.com)
- A sensory branch of the mandibular nerve (CN V3) It passes through the parotid gland en route to the ear, where it innervates skin of the pinna, external auditory canal, and tympanic membrane. (unboundmedicine.com)
- A narrowing of the spinal canal caused by cervical spinal stenosis may cause neck pain on either side of the neck. (sehatnagar.com)
Network of nerves1
- The CNS and the body components are connected through a network of nerves. (neurologyconference.com)
Responsible for sensory1
- Some of the cranial nerves are responsible for sensory and motor functions as they contain only sensory fibres and motor fibres. (byjus.com)
Consists1
- The spinal cord consists of bundles of nerve. (msdmanuals.com)
Cord injury5
- Background Spinal cord injury is associated with urinary and erectile dysfunction. (eg.net)
- Methods The study included 30 male patients with bladder and erectile dysfunction (precipitancy overactive bladder) after traumatic partial spinal cord injury above the level of T12 within 6-18 months after injury. (eg.net)
- Spinal cord injury (SCI) is not a notifiable disease and therefore figures for the annual incidence are inaccurate and may vary on the basis of the source. (eg.net)
- Trauma is the most common cause of spinal cord injury. (medscape.com)
- Bladder function (leakage / obstruction) can be affected without spinal cord injury or disease. (instituteofurology.in)
Pairs3
- The cerebral aqueduct contains the nuclei of two pairs of cranial nerves , the oculomotor nuclei and the trochlear nuclei. (databasefootball.com)
- There are eight pairs of cervical nerves. (neupsykey.com)
- The spinal nerves ( nervi spinales ) (Figs. 17-1 and 17-2 ) usually number 36 pairs in the dog. (veteriankey.com)
Structures3
- Moreover, many peripheral nerve injuries can be associated with other soft-tissue or bone injuries that can be detected at radiography, while computed tomography (CT) scanning can be used in the investigation of occult fractures that are not depicted on plain radiographs, and conventional magnetic resonance imaging (MRI) can be employed to visualize normal and abnormal peripheral nerve structures. (medscape.com)
- The neurologic clinician must, therefore, be very familiar with these structures and their relationship to the spinal cord. (neupsykey.com)
- At the peripheral ends of nerves, specialized structures called nerve endings or receptors are present. (bioguideline.com)
