Question

What is the structure of the seminiferous tubule?

Answer 1

Seminiferous Tubule:

1. The testes are the male reproductive organs.
2. Each testis contains approximately 250 testicular lobules or compartments.
3. Each testicular lobule contains roughly two seminiferous tubules, which are responsible for producing sperm.
4. They account for around 90% of the testicular volume.
5. The three tissue layers that make up the wall of seminiferous tubules are the basal lamina, stratified epithelial layer, and outer tunica propria.
6. The seminiferous tubules display differentiating spermatogenic cells at various stages of spermatogenesis in an organized manner.
7. Sertoli cells are the large sustentacular cells that extend from the capsule to the lumen of the seminiferous tubule.
8. They maintain, nourish, and control the growth of cells going through spermatogenesis.
9. The endocrine cells present in the space between seminiferous tubules are termed as interstitial cells of Leydig.
10. They synthesize and secrete androgens.
