Answer 2

Answer:

Histology of testes:

The testis is surrounded by three protective layers which are known as tunicae. These three layers are Tunica vaginalis, Tunica albuginea, and Tunica vasculosa. Each testis contains about 250 compartments called testicular lobule and each lobule contains one to three highly coiled seminiferous tubules where sperms are produced. The stratified epithelium of seminiferous tubules is made up of two type of cells- Sertoli cells and Spermatogenic cells or male germ cells.

Sertoli cells are elongated and pyramidal which partially envelope the spermatogenic cells and nourish the spermatozoa. Spermatogenic cells are stacked in 4-8 layers that occupy the space between the basal lamina and the lumen of the tubule. These cells divide several times and differentiate to form spermatozoa.

Between the seminiferous tubules are present the Leydig cells. These cells secrete testosterone hormone that controls spermatogenesis.
