Question 21

Superficial cut on the thumb would follow the cephalic vein. Where does lymph from cephalic v. path empty into?

Answer 21

Cephalic vein bypasses the lateral nodes and empties directly into the apical nodes.

Where does lymph from a superficial cut on the medial side of the hand would follow the basilic vein empty into?

Answer 22

lateral nodes—and then drain into the central and apical nodes.
