MEDICAL PHYSIOLOGY

Detailed explanation-1: -Spermiogenesis. The transformation of spermatids into spermatozoa is called spermiogenesis. During this process pronounced changes occur in the nucleus and cytoplasm. The nucleus becomes progressively darker and elongated.

Detailed explanation-2: -The two maturation divisions of each spermatocyte result in four haploid cells, namely the spermatids. These differentiate into mature spermatids, a process called spermiogenesis which ends when the cells are released from the germinal epithelium. At this point, the free cells are called spermatozoa.

Detailed explanation-3: -During spermiogenesis, young spermatids undergo complex morphological, biochemical and physiological changes that result in the formation of highly polarized flagellated spermatozoa. Many of the changes that occur during this time are essential for the production of fertile sperm.
