The mediastinum testis is a thick yet incomplete septum at the posterior part of the testis formed by the tunica ... The septa testis - extensions of the tunica ...
The septa testis are fibrous partitions of the testis dividing the testis into compartments - the lobules of the testis. The septa are formed by extensions of the tunica albuginea - the dense fibrous connective tissue surface covering of the testis - into the substance of the testis. The septa converge towards the mediastinum testis. [1]
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 ...
The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis. Each lobule is contained in one of the intervals between the fibrous septa which extend between the mediastinum testis and the tunica albuginea , and consists of from one to three, or more, minute convoluted ...
The rete testis (/ ˈ r iː t i ˈ t ɛ s t ɪ s / REE-tee TES-tis; pl.: retia testes) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the homologue of the rete ovarii in females. [1]
The tunica vasculosa testis (vascular layer of testis) is the inner-most of the three layers that form the capsule of the testis. It consists of a vascular plexus and loose connective tissue . It extends into the testis itself to line the surfaces of individual septa of testis .
Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum. During its descent it carries along with it the vas deferens, its vessels, nerves etc. There is one on each side.
The tunica albuginea is the fibrous envelope that extends the length of the corpus cavernosum penis and corpus spongiosum penis. It is a bi-layered structure that includes an outer longitudinal layer and an inner circular layer.
