Select the correct statement regarding the diagrammatic sectional view of a seminiferous tubule.
Options
- ASpermiation is the process of sperm release from the Sertoli cells into the lumen of the seminiferous tubule.
- BSpermatogenesis refers to the transformation of spermatids into mature spermatozoa.
- CSertoli cells are primarily involved in producing testosterone.
- DPrimary spermatocytes undergo mitosis to form secondary spermatocytes.
Correct answer
A. Spermiation is the process of sperm release from the Sertoli cells into the lumen of the seminiferous tubule.
Step-by-step solution
The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis. After spermiogenesis,sperm heads become embedded in the Sertoli cells, and are finally released from the seminiferous tubules by the process called spermiation. Sertoli cells provide nutrition to the germ cells. A primary spermatocyte completes the first meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes.
