Question

How many statements is/are correct?
(A) Premordial germ cells are $2$n in nature.
(B) Spermipgenesis occurs in epididymis.
(C) Galea capitis is cap like structure found at head of sperm.
(D) Corpus spongiosum is covered by tunica albuginea.

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

Answer: (D)

Four

For the first statements we can say that, 1. The primordial germ cells are the common origins of spermatozoa and oocytes and thus represent the ancestors of the germline Like all other somatic cells these are diploid and in human embryos can already be found in the primary ectoderm (epiblast) in the second week. 2. Spermiogenesis the process by which spermatids become spermatozoa Sperm gain motility in the epididymis Capacitation is the process by which spermatozoa become motile and are fully mature this does not occur until they are in the female reproductive tract. 3. The head of the sperm is formed by a condensed nucleus a thin cytoplasm and thin cell membrane The anterior two-thirds of the head is like a thick cap called acrosome and it is covered by a membrane and it is collectively called as galea capitis. 4. The tunica albuginea forms a thick fibrous coat to the spongy tissue of the corpora cavernosa and corpus spongiosum It consists of two layers the outer longitudinal and the inner circular The tunica albuginea becomes thicker centrally where it forms a groove to accommodate the corpus spongiosum
So, the correct option is option D
