Each seminiferous tubule is lined on its inside by:

1. Spermatogonia

2. Primary spermatocytes

3. Sertoli cells

4. Both 1 and 3

Leydig cells:

1. Are present in seminiferous tubules and secrete androgens

2. Are present in seminiferous tubules and help in maturation of sperms

3. Are present in interstitial space and secrete androgens

4. Are present in interstitial space and help in maturation of sperms

The structure of testis of a mammal can be identified by the presence of

(1) Spermatogonia

(2) Spermatocytes

(3) Cells of Sertoli

(4) Spermatids

Which of the following is wrong?

Which of the following depicts the correct pathway of transport of sperms?

In the vertebrates testes, for nourishment during spermiogenesis, the spermatids get attached to

(1) Interstitial cells

(2) Sperm-mother cells

(3) Spermatocytes

(4) Sertoli cells

The level of which hormone gets increased first and stimulate spermatogenesis at puberty?

FSH:

1. Acts on Sertoli cells and stimulates secretion of some factors that help in spermiogenesis

2. Acts on Sertoli cells and inhibits secretion of some factors that help in spermiogenesis

3. Acts on Leydig cells and stimulates secretion of some factors that help in spermiogenesis

4. Acts on Leydig cells and inhibits secretion of some factors that help in spermiogenesis

Arrange the following process starting from the germ
cells of seminiferous tubule?
