Tunica albuginea of testis

Tunica albuginea of testis

Tissue surrounding the testicle

For other structures with the same name, see Tunica albuginea.

The tunica albugine is a dense,[1][2] blue-white[3] layer of fibrous tissue surrounding the testis.[1][4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).[5]

Quick Facts Details, Identifiers ...

The connective tissue of the tunica albuginea testis extends into the substance of the testis to form fibrous partitions - the septa testis.[1] At the posterior aspect of the testis (where the serosa of testis is deficient to allow for the attachment of the epididymis), the tunica albuginea extends into the testis to form the mediastinum testis.[5]

Anatomy

It is thicker than the tunica albuginea of the ovary.[6]

Histology

It is composed of bundles of white fibrous connective tissue (from which it derives its name albuginea) which interlace in every direction.[7]
