PRACTICE SOLUTION STUDY GUIDE
◉ Process of spermatogenesis Answer: Spermatogonia (germ cells)-
- Primary spermatocyte (2n)-- Meiosis I occurs-- Secondary
spermatocytes 2 of (n), Meiosis II occurs-- Spermatids 4 of (n)--
Spermiogenesis (production of sperm)
◉ Semen Answer: Mixture of sperm and seminal fluid. Comes from
the secretion of seminal vesicle, prostate, bulbourethral gland, and
seminiferous tubule
◉ What do the ovaries produce? Answer: estrogen, progesterone,

Secondary oocyte (n)+ first polar body(n)-- Secondary oocyte
released-- fertilization by sperm-- ovum-- zygote(2n)
, ◉ One primary oocyte gives rise to how many ovum? Answer: 1
◉ One primary spermatocyte produces how many gametes/
Answer: 4
◉ What layer sheds during mensuration? Answer: stratum
functionalis
◉ oxytocin function Answer: uterine contractions and milk ejection
◉ FSH in females Answer: stimulates development of ovarian
follicles and ovulation
◉ LH in females Answer: stimulates ovulation and corpus luteum

◉ hCG Answer: secreted by chorion (trophoblast) of the embryo and
