The Shoulder: Pectoral, Scapular, and Deltoid Regions Flashcards
what is the flow of blood in the arm in basilic starting at the digit branches
axillary vein <- basilic vein (joins with brachial vein) <- (either) superfical palmar veins or the dorsal veins and (medially) dorsal arch <- digit branches
what is the flow of blood in the arm starting at the cephalic vein
cephalic vein -> the dorsal venous network and lateral part of the dorsal arch -> digit branches
the cephalic vein travels in what structure
the deltopectoral groove
the medial cubital vein drains into the
cuboid fossa
the cutaneous veins of the upper extremity are used for
storage in case of an injury. it is released by the sympathetic nervous system
basilic and cephalic vein communicate via
median cubital vein
lympathic drainage goes into the for UE (mostly)
axillary nodes
the ______________ divide the arm into anterior and posterior compartments. it also houses veins and arteries.
intermuscular septa
the _____________ divides the forearm into anterior and posterior compartments
interosseous membrane
the cubital fossa contains
the median cubital vein, basilic vein, and cephalic vein
intercostobrachial nerve supplies what region
the skin of the armpit and pat of the posterior intermediate aspect of the arm
supraclavicular supplies what region
supply the pectoral region and superior half of the shoulder region
Superior/upper lateral brachial cutaneous nerve / superior/upper lateral cutaneous nerve of the arm supplies
Supplies the inferior half of the shoulder region extending
slightly into the arm

The suprascapular nerve and artery meet at the _____________ where do they both go once they reach there?
suprascapular notch, the suprascapular artery goes over the suprascapular ligament and the nerve goes under the suprascapular ligament
suprascapular artery supplies the
supraspinatus muscle, infraspinatus, and teres minor
