Anatomical terminology
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]
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.
