QUESTION
Pre scrotal sigmoid flexure is present in…?
OPTIONS
(A) Ox
(B) Stallion
(C) Boar
(D) Dog
ANSWER
(C) Boar
EXPLANATION
The boar has a fibroelastic penis with its sigmoid flexure located cranial to the scrotum, termed prescrotal. In the ox, the sigmoid flexure is postscrotal. Stallions and dogs have musculocavernous penises and lack this characteristic sigmoid flexure. The location and penile type therefore distinguish the boar from all three alternative species.
