Question

Spermiation is
A. Release of fluid of prostate
B. Release of spermatids from Sertoli cells
C. Release of semen from Vas deferens
D. Ejaculation from penis

Answer 1

Hint: The process of Spermiation is not a process that is included in the spermatogenesis, but it helps in the final stage of the production of sperms. This takes place in specialized structures of the testis. This cycle is likely to happen more than a few days at the apical edge of the seminiferous epithelium.

Complete answer:
The cycle that aids in the development of spermatids that are delivered from Sertoli cells into the seminiferous tubule, which is a lumen that is available before their entry to the epididymis is known as Spermiation. This cycle is likely to happen more than a few days at the apical edge of the seminiferous epithelium and includes a few discrete advances including the rebuilding of the spermatid head and cytoplasm, expulsion of specific attachment structures, and the last withdrawal of the spermatid from the Sertoli cell.
Spermiation is refined by the organized communications of different structures, cell cycles, and attachment buildings that make up the Spermiation machinery. This audit addresses the morphological, ultrastructural, and utilitarian parts of mammalian Spermiation. The atomic creation of the Spermiation hardware, its dynamic changes, and administrative elements are analyzed. The impact on sperm morphology and their function are assessed to understand the causes for the Spermiation failure and how this process would result in sperm count suppression during contraception and to phenotypes of male infertility.

Thus, the correct answer is option( B) Release of spermatids from Sertoli cells.

Note:
In testis, there are mother cells known as the spermatogonium, which is diploid and contains forty-six chromosomes. These cells differentiate to form primary spermatocytes. A primary spermatocyte would complete the first meiotic or the educational cell division and produces two equal haploid secondary spermatocytes. The secondary spermatocytes would undergo the second meiotic division to produce four equal, haploid spermatids. These spermatids, which are formed, will be transformed into the sperms and that process is commonly known as spermiogenesis. After this process, the heads of the sperm are embedded in the Sertoli cells, and they are finally released from the seminiferous tubules by the process called Spermiation.
