corpus cavernosum

Etymology: L, body + caverna hollow place
a type of spongy erectile tissue within the penis or clitoris. The tissue becomes engorged with blood during sexual excitement.

corpus cavernosum

Either of two cylindrical columns of spongy tissue that run superolaterally to the corpus spongiosum over the length of the penis. Mechanical stimulation of the penis triggers the parasympathetic division of the autonomic nervous system with minimal input from the central nervous system, releasing acetylcholine from the sacral nerves, which in turn releases nitric oxide from the endothelial cells of the trabecular arteries, resulting in vasodilation and engorgement of the corpora cavernosa with blood and an erection. When the parasympathetic stimulation subsides, the corpora cavernosa return to a relaxed state.

corpus cavernosum

one of a pair of laterally situated masses of erectile tissue in the mammalian penis which, together with the CORPUS SPONGIOSUM, causes the erection of the penis when filled with blood.

Corpus cavernosum (plural, corpora cavernosa)

One of two rods of spongy tissue in the penis that become engorged with blood in order to produce an erection.
