LECTURE 9 axilla, surface anatomy, blood supply of upper extremity Flashcards
what does axilla mean?
armpit
ventral boundary of axilla
pectoral muscles (pectoral folds)
dorsal boundary of axilla
latissimus dorsi, teres major, subscapularis
medial boundary of axilla
serratus ventralis
lateral boundary of axilla
intertubercular groove of humerus
contents of axilla
axillary lymph nodes, axillary vessels, brachial plexus
arteries of upper extremty
subclavian (thoracic cavity), axillary (armpit), subscapular, circumflex humeral arteries, brachial (arm), deep brachial, radial (forearm), ulnar (forearm), common interosseous, superficial and deep palmar arches, digital
deep veins of upper extremity
deep palmar venous arches, radial (forearm), ulnar (forearm), brachial (arm/elbow), axillary (axilla), subclavian (thoracic cavity)
superficial veins of upper extremity
digital, superficial palmar venous arches, median (forearm), median cubital (elbow), cephalic (lateral arm/forearm), basilic (medial arm/forearm)
description of cubital fossa
anterior surface of elbow
contents of cubital fossa
median cubital vein (blood draw), brachial artery, median nerve
medial boundary of cubital fossa
pronator teres
lateral boundary of cubital fossa
brachioradialis
superior boundary of cubital fossa
line between epicondyles
description of carpal tunnel
carpals concave anteriorly, flexor retinaculum (carpal ligament) covers it, contains long tendons of flexor muscles and median nerve, inflammation of tendons causes compression of median nerve (carpal tunnel syndrome)
