Visceral layer The
visceral layer of tunica vaginalis of testis (
lamina visceralis tunicae vaginalis testis) is the portion of the tunica vaginalis that covers the testis and
epididymis. It is the superficial-most of the three layers that constitute the capsule of the testis, with the
tunica albuginea of testis situated deep to it. Posteriorly, the visceral layer does not line the surface of the testis - instead, it passes onto the
epididymis where the latter attaches to the testis before continuing onto the inner surface of the scrotum as the parietal layer.
Parietal layer The
parietal layer of tunica vaginalis of testis (
lamina parietalis tunicae vaginalis testis) is the portion of the tunica vaginalis that lines the inner surface of the
scrotum. It is supported by the
internal spermatic fascia.

Fascia spermatica interna The
cavity of the tunica vaginalis (also:
cavum of the tunica vaginalis, or
cavum vaginale) is the cavity between the visceral layer and the parietal layer of tunica vaginalis. It is normally occupied by a small amount of clear, lightly coloured
fluid. The volume of the fluid in the cavity may
increase abnormally when lymphatic drainage is impeded (due to inflammation, neoplasm, or trauma). == Development ==
