Electromyography revealed sig-nificantly less co-contraction of the lower leg muscles, due to a more phasic instead of a tonic activity of the tibialis anterior muscle, and an improved activation pattern of the left rectus and biceps femoris muscles. (iospress.com)

Patients do experience moderate discomfort during a popliteal block because the needle traverses through the biceps femoris. (medscape.com)

This allows us to examine the peroneal head, where the peroneal nerve is most likely to be injured, when we next stimulate the popliteal fossa. (drsashimi.com)
The goal of this technique is to spread the local anesthetic inside the sciatic nerve sheath and the popliteal fossa. (nysora.com)
But, you really should make your selection not based on what you do best, but what the anatomical configuration of the sciatic nerve in the popliteal fossa is. (nysora.com)
Dr. Hadzic showing the popliteal fossa crease and anatomic surface points where you will be able to see the sciatic nerve. (nysora.com)
Now, the sweet spot for this nerve block is when you start acquiring images just above the popliteal fossa crease, and then you move your transducer more proximally. (nysora.com)

Also, be aware that the peroneal nerve will react if it is on the outside or closer to the fibula. (drsashimi.com)
For example, the biceps femoris extends the thigh at the hip and inserts on the lateral side of the fibula. (nielasher.com)

Each receives a gray ramus communicans from the corresponding ganglion of the sympathetic trunk, while from the third and frequently from the second and the fourth sacral nerves, a white ramus communicans is given to the pelvic plexuses of the sympathetic. (bartleby.com)

The nerve also partially supplies the adductor magnus muscle along the inner front side of the thigh. (spine-health.com)
The muscular division (i.e. rami musculares) are spread to the muscles of the lower limb, for example, adductor magnus, biceps femoris, semimembranosus as well as semitendinosus. (backcarechiropractic.com)

When looking at bodybuilders, however, the biceps femoris and the semitendinous muscle appear joined behind their tendinous insertions. (exploreplasticsurgery.com)
The nmluy caveat to that possibility is that the semitendinous muscle is divided into two sections by a visible ridge of tendinous tissue (raphe) which can be problematic for making a smooth confluent subfascial implant pocket. (exploreplasticsurgery.com)

The semimembranosus has been dissected to illustrate the entrance of branches of the sciatic nerve into the muscle. (stanford.edu)

The four muscles that make up the quadriceps are the strongest and leanest of all muscles in the body. (healthline.com)
The quadriceps femoris is a group of muscles located in the front of the thigh. (healthline.com)

In the biceps femoris, this junction extends over most of its entire length. (medscape.com)

The common peroneal branch of the sciatic nerve is derived from the L4, L5, S1, and S2 spinal nerves. (spine-health.com)
The common peroneal, also known as the common fibular nerve, innervates the lateral aspect of the leg and dorsum of the foot. (medscape.com)
For this reason, the peroneal nerve is the most frequently affected by neuropathy and edema. (drsashimi.com)
It was observed motor nerve conduction velocity, amplitude and latency of the peroneal nevre more than affected to tibial nerve. (jpmrs.org)
Conclusion: In our study, it was determined that peroneal nerve more than affected tibial nerve. (jpmrs.org)

All of the muscles of the hamstrings originate on the ischial tuberosity. (medscape.com)

In time, however, the lateral plantar nerve and its branches were noted to be a more common site of entrapment. (medscape.com)
In addition, others have more specifically identified entrapments involving the first branch of the lateral plantar nerve and the calcaneal nerves. (medscape.com)

Karmakar MK, Reina MA, Sivakumar RK, Areeruk P, Pakpirom J, Sala-Blanch X. Ultrasound-guided subparaneural popliteal sciatic nerve block: there is more to it than meets the eyes. (medscape.com)
The sciatic nerve block was performed prior to the claw amputation under general anesthesia. (openveterinaryjournal.com)

Muscles and tendons, Peripheral nervous system, Thigh. (stanford.edu)
Although it has become common to refer to the long muscles at the back of the thigh as the hamstring muscles or the hamstrings, they are in fact the the tendons that attach the large muscles at the back of the thigh to bone. (nielasher.com)
The hamstring muscles themselves are the large muscles that pull on those tendons. (nielasher.com)
Although the tendons themselves can sometimes be involved in injuries, in this blog we refer to the hamstrings as the large muscle group at the back of the thigh as this is where our clients most frequently encounter tightness, trigger point activity and injury. (nielasher.com)
If you have a multi-muscle injury, it normally occurs at the point where your hamstring muscles and tendons meet (musculotendinous junction) at the top of the hamstring muscles. (aidmymuscle.com)
However, hamstring pulls can also occur at any place along the hamstring muscle bellies or in the tendons that attach the muscles to the bones. (aidmymuscle.com)

AIM: to describe the efficacy of sonography (ultrasound) in the diagnosis of chronic muscular lesions and in the prevention of the risk of recurrence in the injured muscle by using dynamic ultrasound and electromyographic examination during static and dynamic strength exercises. (jortho.org)
Intramuscular injection of donor muscle-derived cells into chimeric cxmd recipients restored dystrophin expression for at least 24 weeks in the absence of post-transplant immunosuppression, indicating that cell transplantation may be a viable therapeutic option for muscular dystrophy. (biomedcentral.com)
The multifocal muscular edema in this case doesn't represent isolated sciatic neuropathy, since muscles innervated by multiple other nerves were also affected. (massgeneral.org)
Sciatic nerve produces the articular plus muscular divisions. (backcarechiropractic.com)

This reduced muscle function results in leg and/or foot weakness. (spine-health.com)
BACKGROUND: Pompe disease usually has muscle weakness due to glycogen accumulation. (bvsalud.org)

Stimulators on this size-scale would allow the electronics and antenna to be entirely integrated into a nerve cuff for peripheral nerve stimulation, and could enable wireless deep brain stimulation. (frontiersin.org)
Isolectin B4 (IB4) labelling was used to define the location within the dorsal horn directly affected by the injury to the peripheral nerve. (biomedcentral.com)
While this limitation exists, the use of ultrasound guidance makes peripheral nerve blocks a viable possibility in the alpaca. (openveterinaryjournal.com)
Abrahamsen, 2009 ), peripheral nerve blocks (PNBs) are not. (openveterinaryjournal.com)
