Hint: This tissue encases the testes and connects to the layers of fibres which surround the epididymis. It is made up of two layers namely; the parietal and visceral laminae.
The parietal laminae cover the greater part of the testes and epididymis, while visceral is far more extensive than parietal.
Complete answer:
Testis is the male reproductive organ. It releases the sperm which fertilizes the ovum in the female body. The testis has various membranes and tissues. One of them is tunica vaginalis. It is the pouch of serous membrane that covers the testes. It is derived from the vaginal process of the peritoneum, which in the fetus precedes the descent of the testes from the abdomen into the scrotum, therefore, it has an abdominal origin.
i. Tunica albuginea: It is a fibrous tissue present at the length of the penis having erectile tissue.
ii. Tunica vasculosa: It is a tissue that has the complex vascular layers for the movement of the blood in blood vessels.
iii. Tunica dartos: It helps in regulating the temperature of the testicles.
Hence, the correct answer is Option (A).
Note: Testosterone is the male sex hormone that helps in the development of the male secondary sexual characters. It is released from the testis. It is a temperature regulating organ which is regulated by the scrotum. There are 2 testicles in males but the sperm production is still possible if only one testis is present.
