The penis is formed by the corpus cavernosum, the urethra, the corpus spongiosum urethrae, terminated by the (/Ians; the vessels, nerves, and a cutaneous investment, which, by its prolongation, forms the prepuce. INTEGUMENTS OF TIIE PENIS AND PREPUCE. These parts are merely a continuation of the common integuments, which are here more delicately thin, and instead of fat, there is, as in the scrotum, only a cellular tissue. At the anterior extremity of the penis the integuments form a greater or less prolongation, which is termed the prepuce, which covers the glans when the penis is in a state of relaxation. The prepuce is connected to the under part of the glans by a triangular fold, termed the frcenum preputii. The prepuce is composed of two membranous layers, between which is a plane of cellular tissue; the outer layer is formed by the skin; the inner is of the nature of a mucous membrane, and is furnished with sebaceous follicles. 2.
