Question

Tunica vasculosa present in testis.
A: Outer to tunica albuginea
B: Inner to tunica albuginea
C: Outer to tunica vaginalis
D: Inner to tunica vaginalis

Answer 1

The testis is part of the male reproductive system surrounded by several layers of tissue. They are tunica vasculosa, tunica albuginea and tunica vaginalis. The first thin and innermost layer of blood vessels. It is a vascular layer consisting of a plexus of blood vessels. The next layer is the thick protective layer. The outermost layer consists of layers. Visceral layer, cavum vaginale and parietal layer.

Complete answer:
Testes are two oval-shaped organs in the male reproductive system. The testis is also known as testicles. They are contained by a sac called the scrotum.
The scrotum is hanged outside the body in the pelvic region between the thigh. The main importance of testes is the production and storage of mature sperms till ejaculation. It produces a hormone called testosterone.
The testes are covered by several layers of tissue, they are Tunica vasculosa, tunica albuginea and tunica vaginalis.
The first thin and innermost layer of blood vessels is Tunica vasculosa. This layer shields the tubular interior of each testicle forms further layers of tissue around the testicle.
The next, thick protective layer made of densely packed fibre is Tunica Albuginea. It is a dense blue-grey membrane composed of white fibrous connective tissue.
The outermost layers of the tissue are called Tunica vaginalis. It consists of layers. Visceral layer, cavum vaginale and parietal layer.
Hence, Tunica vasculosa is present inner to the tunica albuginea.

Hence, the correct option is B.

Note:
The testis is the male reproductive gonad in all animals. It produces sperm and androgen primarily testosterone. Seminiferous tubules, rete testis, efferent ducts and tunica are present in the testis. Tunica is the covering present in the testis. They are Tunica vasculosa, Tunica albuginea, Tunica vaginalis. Tunica vasculosa is the innermost thinnest layer. Tunica albuginea is the next protective layer with dense fibre. The outermost layer is the Tunica vaginalis.
