Lab 2: Gross Anatomy of the Peripheral Nervous System

(Innervation/Anatomical Pathway) Sternocleidomastoid and trapezius muscles

(Innervation/Anatomical Pathway) Spinal Accessory n. XI (motor)

(Innervation/Anatomical Pathway) muscles of the tongue

(Innervation/Anatomical Pathway) Hypoglossal N. XII (motor)

(Innervation/Anatomical Pathway) both motor and sensory fibers to the visceral body organs

(Innervation/Anatomical Pathway) Vagus Nerve X (both motor and sensory)

(Pathology) Clinical manifestations may include dysphagia, vocal cord weakness and alterations of the parasympathetic tone of the thorax and abdomen

(Pathology) Vagus Nerve X (both motor and sensory)

(Innervation/Anatomical Pathway) Lower Eyelid and Upper Lip; infraorbital canal

(Innervation/Anatomical Pathway) Infraorbital Nerve

(Innervation/Anatomical Pathway) diaphragm muscles to control breathing; both ______ run from C3 - C5 along the anterior scalene muscle before diving into the thorax to pass between the lungs and heart

(Innervation/Anatomical Pathway) Phrenic Nerve

(Innervation/Anatomical Pathway) supraspinatus and infraspinatus muscles; subscapular notch of the scapula

(Innervation/Anatomical Pathway) Suprascapular Nerve

(Innervation/Anatomical Pathway) subscapularis, teres major and latissimus dorsi muscles

(Innervation/Anatomical Pathway) Subscapular Nerve

(Innervation/Anatomical Pathway) deltoid and teres minor muscles

(Innervation/Anatomical Pathway) axillary nerve

(Innervation/Anatomical Pathway) coracobrachialis, biceps brachii, and brachialis muscles

(Innervation/Anatomical Pathway) musculocutaneous nerve

(Innervation/Anatomical Pathway) triceps brachii and all muscles of the posterior forearm, sensation to lateral posterior surface of the hand; radial groove of the humerus bone

(Innervation/Anatomical Pathway) Radial nerve

(Pathology) when damaged an individual cannot draw their wrist up and thus this condition is referred to as wrist drop

(Pathology) Radial nerve

(Innervation/Anatomical Pathway) sensation to lateral anterior hand

(Innervation/Anatomical Pathway) Median nerve

(Pathology) carpal tunnel syndrome is generally associated with compression of this nerve

(Pathology) Median nerve

(Innervation/Anatomical Pathway) sensation to the anterior and posterior medial hand; behind the medial epicondyle of the humerus

(Innervation/Anatomical Pathway) Ulnar Nerve

(Pathology) superficial and thus often exposed to contact stimulation and pain in the “funny bone”

(Pathology) Ulnar Nerve

(Innervation/Anatomical Pathway) serratus anterior muscle

(Innervation/Anatomical Pathway) Long Thoracic Nerve

(Pathology) when this nerve is damaged, the scapula wings out as it can no longer be held against the body wall

(Pathology) Long Thoracic Nerve

(Innervation/Anatomical Pathway) biceps femoris, semitendinosus and semimembranosus

(Innervation/Anatomical Pathway) sciatic nerve

(Innervation/Anatomical Pathway) gastrocnemius, soleus, and plantaris muscles

(Innervation/Anatomical Pathway) Tibial nerve

(Innervation/Anatomical Pathway) anterior muscles of the leg (not the thigh)

(Innervation/Anatomical Pathway) common fibular nerve

(Pathology) when damaged the 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

(Pathology) common fibular nerve

(Innervation/Anatomical Pathway) rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius muscles

(Innervation/Anatomical Pathway) femoral nerve

(Innervation/Anatomical Pathway) sensation to the lateral thigh

(Innervation/Anatomical Pathway) Lateral Cutaneous Nerve

(Innervation/Anatomical Pathway) sensation to the medial thigh; obturator foramen of the hip

(Innervation/Anatomical Pathway) obturator nerve

(Innervation/Anatomical Pathway) sensation to the medial leg and medial ankle/foot

(Innervation/Anatomical Pathway) saphenous nerve

(Innervation/Anatomical Pathway) distributes fibers through the ramus communicans for sympathetic influence into spinal nerves

(Innervation/Anatomical Pathway) Sympathetic Trunk and Ganglia
