Question

What is Spermatogenesis —- process of making sperm, involves mitosis AND meiosis. please Expain in detail and this question belongs to human anatomy

Answer 1

The process of development of the spermatozoa is known as spermatogenesis. The development occurs in the seminiferous tubules of the testis. The spermatozoas are developed from the spermatogonia which are the germinal cells and are diploid. These cells divide by mitosis. Two type of cells are formed by division. Type A and type B cells. Type A cells reloads the spermatogonia and the type B cells differentiates into the Primary Spermatocytes which are also diploid. The primary spermatocytes undergoes meiosis I to produce 2 secondary spermatocytes which are haploid. The two secondary spermatocytes further undergoes meiosis II to produce two haploid spermatids each respectively. Therefore, 4 haploid spermatids are formed after meiosis II. The spermatids are developed into spermatozoas through the process of spermiogenesis. Thus, 4 spermatozoas are formed which are haploid. Active sperm cells from the spermatozoas are formed in the epididymis.
