trabeculae of corpus spongiosum of penis





























the fibrous envelope of the corpus cavernosum urethrae is thinner, whiter in color, and more elastic than that of the corpora cavernosa penis. it is called the trabeculae of corpus spongiosum of penis.





























the trabeculae are more delicate, nearly uniform in size, and the meshes between them smaller than in the corpora cavernosa penis: their long diameters, for the most part, corresponding with that of the penis.

clitoral erection occurs when the corpora cavernosa, two expandable erectile structures, become engorged with blood. this may result from any of various physiological stimuli, including sexual arousal. during sexual arousal, arterial blood flow to the clitoris is increased, and trabecular smooth muscle within the clitoris relaxes allowing blood to engorge the erectile tissues. the ischiocavernosus and bulbocavernosus muscles contract to compress the dorsal vein of the clitoris to stop drainage of the clitoris, trapping the blood. more specifically, the clitoris has two adjoining erectile tissues corpus cavernosa (corpus cavernosa clitoridis) that form a main body that connects to the glans clitoridis. there is also a strip of erectile tissue (similar to the placement of the corpus spongiosum in males) running along the ventral surface of the corpus cavernosa main body that connects the glans clitoridis to the commissure of the vestibular bulbs. the main body of the corpus cavernosa with a ventral erectile tissue strip make up the shaft, which is connected to the glans clitoridis. the tunica albuginea is a fibrous-elastic sheath, surrounds the shaft and glans clitoridis. the tunica albuginea does not surround the bulbs of vestibule. the erectile tissues are composed of endothelium-lined vascular spaces in a trabecular matrix, with the endothelium-lined vascular spaces surrounded by smooth muscle capable of contraction and relaxation.
