Peripheral muscle and nerve. Medical search. Frequent questions

Muscle weakness or complete paralysis may be secondary to an interruption in the communication between the brain and nerve cells in the spinal cord that govern muscle activation, or to an interruption in the lower motor neuron or peripheral nerve (including the motor nerve cells in the spinal cord and their processes which connect with the muscle fibers), or both.

Schwann cells are the cells in the peripheral nervous system that create and maintain myelin sheaths on neurons. (wikipedia.org)
Myelin-associated glycoprotein (MAG) is a glycoprotein that is specific to Schwann cells, which create myelin for nerve cells in the peripheral nervous system. (wikipedia.org)

Stanford Health Care's Peripheral Nerve Surgery Program offers comprehensive diagnostic evaluation and testing, as well as leading-edge surgical techniques, provided by a highly specialized and experienced nationally-recognized team. (stanford.edu)

The impulse travels out of the spinal cord along the length of the motor nerve. (msdmanuals.com)

SOAP guidelines also recommend consideration of local anesthetic (LA) techniques, including regional nerve blocks, in situations when long acting neuraxial morphine is not used. (asra.com)

A more complex nerve sheath tumor may assume the shape of a dumbbell. (mayoclinic.org)

If the sciatic nerve is affected due to inflammation or compression, the function of the muscles that it supplies may be reduced. (spine-health.com)

The mechanism of pain perception has individual peripheral receptors and includes a complex and chemically unique set of central circuits 7 . (nature.com)

But they can lead to pain, nerve damage and loss of function in the affected area. (mayoclinic.org)
Data at this time suggest peripheral nerve blocks provide analgesic benefit in cases where intrathecal morphine cannot be utilized or as a rescue technique for refractory pain. (asra.com)
These nerves control your sense of touch, how you feel pain and temperature, and your muscle strength. (stlukesonline.org)
The doctor may check your muscle strength and ability to feel touch, temperature, and pain. (stlukesonline.org)
Over-the-counter medicine can relieve mild nerve pain. (stlukesonline.org)
These overactive nerves cause your child to feel more extreme (amplified) pain. (clevelandclinic.org)
The result is a quick response of a muscle-by immediately withdrawing from whatever is causing the pain. (msdmanuals.com)

A. Transverse scan showing the radial nerve (yellow arrowhead) and the deep brachial artery (red arrowhead). (usra.ca)
B. The use of Color Power Doppler to identify the deep brachial artery lateral to the radial nerve (yellow arrowhead). (usra.ca)
The solitary radial nerve appears predominantly hyperechoic at this region. (usra.ca)
The radial nerve (arrowheads) becomes elliptical and linear as it divides into the superficial and deep branches. (usra.ca)
The radial nerve (arrowheads) is visualized below the elbow lying immediately next to the radius bone. (usra.ca)
