-
phrenic nerve
sole motor nerve supply to the diaphragm; hiccups; chief muscle causing breathing movements
-
median (branches of the brachial plexus)
activates muscles that pronate the forearm, flex the wrist and fingers and oppose the thumb
-
ulnar (branches of the brachial plexus)
innervates most intrinsic hand muscles and the skin of the medial aspect of the hand. it causes the wrist and fingers to flex and adducts and abducts the medial fingers
-
radial (branches of brachial plexus)
muscles controlled by the radial nerve extend the elbow, supinate the forearm, extend the wrist and fingers, and abduct the thumb
-
femoral nerve (lumbar plexus)
motor branches innervate anterior thigh muscles which are the principle thigh flexors and knee extensors. the cutaneous branches serve the skin of the anterior thigh and the medial surface of the leg from knee to food
-
obturator nerve (lumbar plexus)
innervates the adductor muscles; sensory for skin of medial thigh and for hip and knee joints
-
saphenous nerve (lumbar plexus)
extends from the femoral nerve; sensory nerve whose function is to send information from the skin to the inside part of the leg; if the skin is in pain, the thigh and leg will feel it
-
sciatic nerve: tibial (sacral plexus)
supplies the posterior compartment muscles of the leg and the skin of the posterior calf and sole of the foot (cutaneous)
-
sciatic nerve: common fibular nerve (sacral plexus)
innervate the knee joint, skin of the anterior and lateral leg and dorsum of the foot, and muscles of the anterolateral leg (cutaneous branches)
