Lab 2 Flashcards
Spinal Accessory XI (motor)
Sternocleidomastoid and trapezius muscles
Hypoglossal XII (motor)
Muscles of the tongue
Vagus nerve X (both)
Both motor and sensory fibers to the visceral body organs
Clinical manifestations may include dysphagia, vocal cord weakness and alterations of the parasympathetic tone of the thorax and abdomen
Infraorbital nerve
Lower eyelid and upper lip; infraorbital canal
Phrenic nerve
Diaphragm muscles to control breathing; both phrenic nerves run from C3-C5 along the anterior scalene muscle before diving into the thorax to pass between the lunges and heart
Suprascapular nerve
Supraspinatus and infraspinatus muscles; suprascapular notch of the scapula
Subscapular nerve
Subscapularis, teres major, and latissimus dorsi muscles
Axillary nerve
Deltoid and teres minor muscles
Musculocutaneous nerve
Coracobrachialis, biceps brachii, and brachialis muscles
Radial nerve
Triceps brachii and all muscles of the posterior forearm, sensation to lateral posterior surface of the hand; radial groove of the humerus bone
When damaged, an individual cannot draw their wrist up and thus this condition is referred to as wrist drop
Median nerve
Sensation to the lateral anterior hand
Canal tunnel syndrome is generally associated with compression of this nerve
Ulnar nerve
Sensation to the anterior and posterior medial hand; behind the medial epicondyle of the humerus
Superficial and thus often exposed to contact stimulation and pain in the “funny bone”
Long thoracic nerve
Serratus anterior muscle
When this nerve is damaged, the scapula wings out as it can no longer be held against the body wall
Sciatic nerve
Biceps femoris, semitendinosus and semimembranosus muscles; greater sciatic notch of the pelvis
Tibial nerve
Gastrocnemius, soleus, and plantaris muscles
Common fibular nerve
Anterior muscles of the leg (not the thigh)
When damaged, muscles in the posterior leg are no longer antagonized by contracting muscles from the anterior leg resulting in an unsynchronized foot drop with each step
Femoral nerve
Rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius muscles
Lateral cutaneous nerve
Sensation to the lateral thigh
Obturator nerve
Sensation to the medial thigh; obturator foramen of the hip
Saphenous nerve
Sensation to the medial leg and medial ankle/foot
Sympathetic trunk and ganglia
Distributes fibers through the ramus communicans for sympathetic influence into spinal nerves
Nerves in spine
Vagus Nerve X
Phrenic nerve
