Visceral lamina[edit] The visceral lamina (lamina visceralis) covers the greater part of the testis and epididymis, connecting the latter to the testis by means of a distinct fold. From the posterior border of the gland it is reflected on to the internal surface of the scrotum.[citation needed]


Parietal lamina[edit] The parietal lamina (lamina parietalis) is far more extensive than the visceral, extending upward for some distance in front and on the medial side of the cord, and reaching below the testis. The inner surface of the tunica vaginalis is smooth, and covered by a layer of simple squamous mesothelial cells. The interval between the visceral and parietal laminæ constitutes the cavity of the tunica vaginalis.[citation needed]


Cavum vaginale[edit] Schematic drawing of a cross-section through the vaginal process. 1 testicle, 2 Epididymis, 3 Mesorchium, 4 Lamina visceralis of Tunica vaginalis, 5 Lamina parietalis of Tunica vaginalis, 6 Cavum vaginale, 7 Epididymis, 8 Fascia spermatica interna The cavum vaginale is the cavity of the tunica vaginalis. The testicle hangs suspended in a space, the cavum vaginale, from which is separated by the visceral layer of the tunica vaginalis. The latter is continued on to the epididymis, at the lateral margins of which it is reflected forward as the parietal layer, and as this is more extensive than the visceral layer, the cavum vaginale-named cavity results. The testicle is enclosed in a thick capsule of fibrous tissue, the tunica albuginea. The tunica albuginea sends prolongations inwards, dividing the testicle into lobules. Each lobule contains the seminiferous tubules, extending from the base where they end blindly, towards the apex.[1]
