Answer to Question 1

Smegma is a thick black waxy material containing sebaceous gland secretions and cells. It has
a foul odor. A bean is a hard ball of smegma that has accumulated in the urethral fossa of the
penis head. Beans are a common cause of sheath swelling or urine flow obstruction.

Answer to Question 2

Cow dermis is very thick, and it is difficult to advance a stylet through the skin without
damaging the catheter tip. A small stab incision made with a No. 15 blade, or a 14g needle
facilitates passage through the skin.
