24 Questions
Which process involves the transformation of spermatid into a spermatozoon?
Spermiogenesis
Where does spermatogenesis occur in males?
Seminiferous tubules of the testes
Which cells provide support and nutrition to germ cells in the process of spermatogenesis?
Sertoli (sustentacular) cells
Which hormone regulates the process of testosterone production in males?
Luteinizing hormone (LH)
What are the segments that make up the tail of a spermatozoon?
Middle piece, principal piece, and end piece
Where are oogonia present in females?
Cortex
During spermatogenesis, primary spermatocytes undergo meiosis II to produce secondary spermatocytes.
False
Spermatids are diploid cells that further specialize to eventually form spermatozoa.
False
Oogenesis involves the formation of several types of germ cells including granulosa cells.
True
Most primordial follicles mature to become oocytes after puberty due to a stimulatory mechanism.
False
Gametogenesis is the process by which mature cells develop into immature gametes like spermatozoa and oocytes.
False
Spermatogenesis takes approximately 90 days to complete in humans.
False
What is the main purpose of gametogenesis?
To produce haploid cells with half the chromosome count
Which of the following describes the process of spermatogenesis?
Production of male germ cells or spermatozoa
What happens to the four haploid cells produced during meiosis in spermatogenesis?
Two of the cells die, leaving two functional sperm
Where does oogenesis primarily occur?
In the ovaries
What is the result of meiosis in oogenesis?
Two functional eggs with half the chromosome count
Which statement accurately distinguishes between spermatogenesis and oogenesis?
Oogenesis produces diploid cells while spermatogenesis produces haploid cells
What is the main function of the acrosomal cap in spermatozoa?
Facilitating penetration of the egg during fertilization
How does oogenesis differ from spermatogenesis in terms of timing?
Spermatogenesis begins earlier in fetal development
Where does the second meiotic division occur in oogenesis if the oocyte is not fertilized?
Fallopian tube
Which statement accurately describes the fate of a mature human egg if not fertilized?
It disintegrates within 24 hours
What is the role of primary spermatocytes in spermatogenesis?
Completing meiosis to become spermatozoa
How does the duration of sperm viability compare to that of eggs outside the body?
Sperm remain viable longer than eggs
