List the types of erectile tissue present in the penis, and explain how the penis becomes erect upon sexual stimulation. What will be an ideal response?
Concepts to Consider: There are three columns of erectile tissue-two are cavernous bodies
and the third is the spongy body. Upon stimulation, nerve impulses cause dilation of the
arteries of the penis. As blood rushes into the vessels of the erectile tissue, they swell and
compress the veins that carry blood away from the penis. The outflow of blood is slowed, and
the erectile tissue becomes further engorged with blood. The penis becomes firm and erect
