The basilic v. begins on the medial end of the dorsal venous network, runs on the medial side of the forearm and the inferior part of the arm; pierces the _____________ fascia into the axilla, where it merges with the accompanying veins of the axillary artery to FORM the _________ v.
test q
brachial, axillary
The median antebrachial vein (median vein of the forearm), begins at the base of the dorsum of the thumb, and ascends in the middle anterior of the forearm between cephalic and basilic veins. It sometimes divides into a median basilic vein, which joins the _______ vein, and a median cephalic vein, which joins the __________ vein.
basilic, cephalic
T/F: deep veins are usually paired and accompany their respective arteries
test q
true
