The Outer Covering of the Testis and Inner Lining of the Scrotum

Question

The outer covering of the testis and inner lining of the scrotum is the ________.
A) tunica albuginea
B) perineal raphe
C) tunica vaginalis
D) scrotal mediastinum
E) None of the answers are correct.

Accepted Answer

The tunica vaginalis is a serous membrane that covers the testis and lines the inner surface of the scrotum. The tunica albuginea is the dense, fibrous capsule that surrounds the testis. The perineal raphe is a visible line that runs down the middle of the scrotum and perineum, separating the left and right sides. The scrotal mediastinum is a fibrous septum that divides the scrotum into two compartments. None of these structures match the description given in the question except for the tunica vaginalis.
