Question

1. the erectile tissues of the penis are the __ and the __.a. corpora cavernosa, tunica albugineab. dartos, glansc. corpus spongiosum, corpora cavernosad. bulbospongiosus, corpus spongiosum

Explanation:

The penis has three columns of erectile tissue. Two are the corpora cavernosa (paired), and one is the corpus spongiosum. The tunica albuginea is a fibrous covering, dartos is a muscle in the scrotum, glans is the tip (not erectile tissue in the sense of the question), bulbospongiosus is a muscle. So we check each option:

• Option a: Tunica albuginea is not erectile tissue.
• Option b: Dartos (muscle) and glans (not main erectile tissue as per the question's context of columns of erectile tissue) are incorrect.
• Option c: Corpus spongiosum and corpora cavernosa are the erectile tissues.
• Option d: Bulbospongiosus is a muscle.

Answer:

C. Corpus spongiosum, corpora cavernosa
