Anatomical terminology

The tunica vaginalis is a pouch of[2] serous membrane[3] within the scrotum that lines the testis and epididymis (visceral layer of tunica vaginalis), and the inner surface of the scrotum (parietal layer of tunica vaginalis). It is the outermost of the three layers that constitute the capsule of the testis, with the tunica albuginea of testis situated beneath it.

It is the remnant of a pouch of peritoneum which is pulled into the scrotum by the testis as it descends out of the abdominal cavity during foetal development.[3]
