what does the third part of the axillary nerve contain?
- lateral border of pectoralis minor to inferior border of teres major muscle
- three branches
_____ : largest branch, divides into circumflex scapular and thoracodorsal arteries, supplies serratus anterior, teres major, subscapularis, and latissimus dorsi muscles.
______: (medial location) continuation of axillary artery, ends in cubital fossa.
_______: lies anterior to triceps and brachialis muscle throughout its course, accompanied by the median nerve
what are the branches of the brachial artery?
- many muscular branches
- profunda brachii artery from medial aspect
- superior and inferior ulnar collateral branches
______: (deep artery of the arm) accompanies radial artery in radial groove, divides into anterior and posterior descending branches to allow.
______: larger of two terminal branches of brachial artery, begins medial to biceps tendon and descends through anterior compartment deep to pronator teres muscle.
what are the branches of the ulnar artery?
- anterior ulnar recurrent
- posterior ulna recurrent
_____: begin in cubital fossa at neck of radius, passes distally deep to brachioradualis muscle, palpable throughout lateral forearm.
what is included in the branches of the radial artery?
- supplies flexor and extensor muscles on lateral side of forearm, radial artery, branches to hand
_______: (branches from the ulnar artery) runs across anterior wrist deep to tendons of flexor digitorum profundus (FDP).
palmar carpal branch
_____: (branches from the ulnar artery) arises proximal to pisiform bone, crosses dorsal to wrist.
dorsal carpal branch
_______: superficial and deep palmar venous arches, dorsal veneers network (arch), both drain to cephalic and basilica veins.
veins of hand
______: basilic vein ascends posteromedially on forearm, cephalic vein ascends on lateral border of forearm, median cubital vein connects cephalic and basilica over cubital fossa.
superficial veins of forearm
_____: paired radial and ulnar veins and interosseous veins accompany arteries of same name, all communicate w/ superficial veins and median cubital vein.
deep veins of forearm
_______: located on anterolateral surface, enters groove b/w deltoid muscle and pectoralis major muscle (deltopectoral groove)
the cephalic vein empties into termination of?
______: located on the medial side, inferior arm, pierces deep fascia at junction of inferior and middle third of arm, runs superiorly to axillary vein.
______: paired, accompany brachial artery, form at elbow from radial and ulnar veins, have valves, merge w/ basilica vein to form axillary vein.
all ____ from arm drains to axillary nodes, including the breasts and thorax.
the brachial plexus is composed of ?
- roots (5)
- trunks (3)
- divisions (6)
- cords (3)
- branches (13 + 4 from roots / terminal branches 5)
______: ventral rami of spinal nerves C5 - T1 ( dorsal scapular nerve C5, long thoracic nerve C5-C7)
______: superior from ventral rami of C5 and 6 (branches nerve to subclavius muscle; suprascapular nerve to supraspinatus muscle, and infraspinatus muscle, shoulder joint), middle from ventral ramps of C7, inferior from ventral rami of C8 and T1.
describe the divisions on the brachial plexus?
- anterior divisions of superior and middle trunks from lateral cord
- anterior divisions of inferior trunk continues as medial cord
- posterior divisions of all three trunks for posterior cord
how are the cords named?
by relationship to axillary artery that they surround (lateral, medial, posterior)
______: pectoral nerve (C5-C7) to pectoralis major and minor muscles, musculocutaneous (C5-C7), root of median nerve (C6-C7).
branches from lateral cord
______: ulnar nerve (C8-T1), brachial cutaneous nerve (C8-T1) supplies skin over medial surface of arm and proximal surface of forearm, and median nerve.
branches from medial cord
_______: upper subscapular nerve (C5-C6) to subscapularis muscle, lower subscapular nerve to teres major muscle and subscapularis muscle, thoracodorsal nerve (C5-C6) to latissimus dorsi muscle, axillary nerve to teres minor muscle and deltoid muscle.
branches from the posterior cord
anterior divisions supply _____ parts of upper limb.
