what muscle and nerve will you need to isolate to study the physiology of nerve fibers? ?
-gastrocnemius and sciatic
or
-sartorius and femoral
or
-triceps brachii and radial
im very confused about this.

Sartorius and femoral is the muscle and nerve that you will you need to isolate to study the physiology of nerve fibers. The correct answer between all the choices given is the second choice. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
