Anatomy & TerminologyQuestion 91 of 100
Which description of antecubital vein anatomy is correct?
a.The basilic vein lies on the lateral or thumb side of the arm
b.The cephalic vein lies laterally and the basilic vein medially, with the median cubital between them
c.The median cubital vein lies deep to the brachial artery
d.The cephalic vein lies on the medial or little finger side
Explanation
In the antecubital fossa the cephalic vein runs along the lateral thumb side, the basilic vein along the medial little finger side, and the median cubital connects them across the middle. The median cubital is superficial and lies above, not beneath, the brachial artery. Reversing the cephalic and basilic positions would put the phlebotomist next to the artery and nerve without realizing it.
