 [ pe´nis] the external male organ of micturition and sexual intercourse.

The body of the penis consists of three cylindrical-shaped masses of erectile weave which run the duration of the penis. Two of the masses lie aboard each other and end behind the head of the penis. The third base mass lies underneath them. This latter mass contains the urethra. The penis terminates in an egg-shaped or conic body, the glans penis, which contains the outside open of the urethra.

The glans penis is covered by a loose clamber, the prepuce or prepuce, which enables it to expand freely during erection. The skin ends good behind the glans penis and folds ahead to cover it. The inner surface of the prepuce contains glands that secrete a lubricate fluid called smegma which makes it easy for the penis to expand and retract past the prepuce .buried penis concealed penis.clubbed penis penile curvature.concealed penis a small penis concealed beneath a fat pad or the skin of the scrotum, abdomen, or thigh; called also a minor penis concealed beneath a fatten pad or the clamber of the scrotum, abdomen, or thigh ; called besides buried penis

The male organ of sexual intercourse and, in mammals, of micturition. It is a cylindrical cernuous organ suspended from the movement and sides of the pubic arch. It is homologous to the clitoris in the female. See : The penis is composed chiefly of erectile weave arranged in three columns, the whole being covered with hide. The two lateral pass columns are the corpus cavernosa penis. The third or median column, known as the principal spongiosum, contains the urethra. The body is attached to the descending dowry of the pubic bone by the crus of the penis. The conic head of the penis, the glans penis, contains the urethral orifice. It is covered with a movable hood known as the prepuce or prepuce, under which is secreted the substance called smegma. hyperemia of the genitals fills the principal cavernosa with blood as the result of sexual exhilaration or stimulation, therefore causing an erection. The hyperemia subsides following orgasm and ejaculation of the seminal fluid. The electric organ then returns to its soft condition. The size of the soft penis does not necessarily correlate with that of the erect penis .

The male organ of copulation containing the The male organ of sexual intercourse containing the URETHRA through which urine and germinal fluid pass. The normally soft penis becomes enlarged and erect by virtue of three longitudinal cylindrical bodies of spongy tissue into which blood can flow under atmospheric pressure under the influence of sexual agitation or early stimuli. One of these bodies, the corpus spongiosum, surrounds the urethra. The other two, the corpus cavernosa, lie side by side above the principal spongiosum. Erection physiology is mediated partially by azotic oxide.
