lab 2 - gross anatomy of peripheral nervous system

spinal accessory n. XI (motor)

innervation: sternocleidomastoid and trapezius muscle

hypoglossal n. XII (motor)

innervation: muscles of tongue

Vagus nerve X (motor and sensory)

innervation: both motor and sensory fibers to the visceral body organs

infraorbital nerve

innervation: lower eyelid and upper lip; infraorbital canal

phrenic nerve

innervation: diaphragm muscles to control breathing; both nerves run from C3-C5 along the anterior scalene muscle before diving into the thorax to pass between the lungs and heart

suprascapular nerve

innervation: supraspinatus and infraspinatus muscles; suprascapular notch of the scapula

subscapular nerve

innervation: subscapularis, teres major and latissimus dorsi muscles

axillary nerve

innervation: deltoid and teres minor muscles

musculocutaneous nerve

innervation: coracobrachialis, biceps brachii, and brachialis muscles

radial nerve

innervation: triceps brachii and all muscles of the posterior forearm, sensation to lateral posterior surface of the hand; radial groove of the humerus bone

median nerve

innervation: sensation to the lateral anterior hand

ulnar nerve

innervation: sensation to the anterior and posterior medial hand; behind the medial epicondyle of the humerus

long thoracic nerve

innervation: serratus anterior muscle

sciatic nerve

innervation: biceps femoris, semitendinosus and semimembranosus muscles; greater sciatic notch of the pelvis

tibial nerve

innervation: gastrocnemius, soleus and plantaris muscles

common fibular nerve(gibes off a superficial and deep branch and is also often cited as the common peroneal nerve)

innervation: anterior muscles of the leg (not the thigh)

femoral nerve

innervation: rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius muscles

lateral cutaneous nerve

innervation: sensation to the lateral thigh

obturator nerve

innervation: sensation to the medial thigh; obturator foramen of the hip

saphenous nerve

innervation: sensation to the medial thigh and medial ankle/foot

sympathetic trunk and ganglia

innervation: distributes fibers through the ramus communicans for sympathetic influence into spinal nerve
