52
blood supply in the upper limb
tube with branching arteries all the way to the hand
53
give the pathway of blood supply to the upper limb
1. subclavian 2.thyrocervical trunk comes off and makes cervical dorsal trunk and two branches. suprascapular and dorsal scapular arteries. (supply the scapula). 3. subclavian travels under clavicle and changes to axillary artery 4. crosses border of pectoralis minor and at the border of teres major, becomes the brachial artery 6. brachial artery branches to deep artery of the arm: supplies posterior arm compartment. ulnar collateral arteries: anastomose around the elbow 7. in the forearm, brachial divides to radial artery: supplies muscles to the lateral aspects of anterior and posterior forearm compartments. forms the ulnar artery: supplies muscles of the medial side of the forearm 8. give digital arteries
54
describe the importance of axilla
provides a passage way for vessels and nerves going to and from upper limb contents: axillary artery and its branches, axillary vein, nerves, branches of brachial plexus, lymphatic vessels, and axillary lymph nodes
55
where is the place to control a hemmorage
middle of the arm
56
veins of the upper limb deep veins
have the same names as arteries -digital veins-venous arches-radial and ulnar veins-brachial vein-axillary vein-subclavian vein
57
radial artery forms what palmar arch
deep palmar arch
58
ulnar artery forms what palmar arch
superficial palmar arch
59
superficial veins of the upper limb
-cephalic veins: continues deep at the deltopectoral triangle and drain into the axillary vein on shoulder -basilic vein: post axial compartment, deep in the arm to join deep veins. drains medial side of the arm and enters into the brachial vein -median cubital vein: superficial link between the cephalic and basilic vein, connects to basilic vein
