PATHOLOGY

Detailed explanation-1: -Spermiogenesis is comprised of four phases: (1) Golgi phase, (2) Cap phase, (3) Tail phase, and (4) Maturation phase. By the end of the last phase, the spermatozoon consists of three distinct parts: the acrosomal head, mid (connecting) piece, and the tail.

Detailed explanation-2: -Step 1: Spermatocytogenesis Each primary spermatocyte then moves into the adluminal compartment of the seminiferous tubules, duplicates its DNA, and subsequently undergoes meiosis I to produce two haploid secondary spermatocytes. Secondary spermatocytes later divide into haploid spermatids.
