- What muscles do the tibial and common fibular nerves innervate?arrow_forwardFor each of the following body regions, name the peripheral nerve that carries somatic motor fibers to most of the skeletal muscles: flexor surface of the arm flexor surface of the forearm extensor surface of the arm and forearm anterior thigh posterior thigh anterior leg posterior legarrow_forwardMedian nerve: show how it branches from the brachial plexus, travels deep to the clavicle, distally down the anterior brachial and antebrachial regions, and eventually passes through the flexor retinaculum to innervate the wrist flexor muscles. Obturator nerve: show how it branches from the lumbar plexus through the obturator foramen to innervate the muscles of the medial thigh, i.e., gracilis and adductors. Sciatic nerve: show how it branches laterally from the sacral plexus at the intervertebral foramen between L5 and S1 and then pass through the greater sciatic notch to the posterior thigh to innervate the hamstrings. Show anterior and posterior image that show the plexus from which the nerve is derived, its pathway though the body, and to the anatomical area where it innervates skeletal muscles. Show either by drawing or using a skeleton model.arrow_forward
