Tunica albuginea: The whitish membrane within the penis that surrounds the spongy chambers (corpora cavernosa). The tunica albuginea helps to trap the blood in the corpora cavernosa, thereby sustaining erection of the penis.

The tunica vaginalis is the serous covering of the testis. It is a pouch of serous membrane, derived from the processus vaginalis of the peritoneum, which in the fetus preceded the descent of the testis from the abdomen into the scrotum.
The tunica vasculosa is the vascular layer of the testis, consisting of a plexus of bloodvessels, held together by delicate areolar tissue.
It clothes the inner surface of the tunica albuginea and the different septa in the interior of the gland, and therefore forms an internal investment to all the spaces of which the gland is composed.
