How many chromosomes are in a human somatic cell? - correct answer ✔✔46 chromosomes,
split into 23 pairs
How many chromosomes are in a sex cell? - correct answer ✔✔23 chromosomes
What is the function of the seminiferous tubules? - correct answer ✔✔where spermatogenesis
takes place
What is the function of the seminal vesicles? - correct answer ✔✔produces an energy supply
nutrient solution (fructose) for sperm
What is the function of the epididymis? - correct answer ✔✔structure where sperm matures
and is stored
What is the function of the prostate gland? - correct answer ✔✔surrounds the urethra at the
base of the bladder
What is the function of the bulbourethral glands? - correct answer ✔✔secretes a solution
important in neutralizing urethra before sperm pass
What is the vas (ductus) deferens? - correct answer ✔✔Tubes from testis to urethra?????
What moves sperm through the ductus deferens? - correct answer ✔✔epididymis???
, Which gonadotropins are released from the anterior pituitary?
What stimulates their release? - correct answer ✔✔-Luteninizing Hormone (LH) & Follicle
Stimulating Hormone (FSH)
-Gonadotropin-releasing hormone (GnRH)
What do luteninizing hormone and follicle stimulating hormone do in a normal adult male? -
correct answer ✔✔-LH stimulates testosterone production from the interstitial cells of the
testes
-FSH stimulates testicular growth and enhances the production of an androgen-binding protein
by the Sertoli cells, which are a component of the testicular tubule necessary for sustaining the
maturing sperm cell
What do luteninizing hormone and follicle stimulating hormone do in a normal adult female? -
correct answer ✔✔-LH stimulates estrogen and progesterone production from the ovary.
-LH surge stimulates ovulation.***
-FSH development of the ovarian follicle, and the secretion of estrogen from this follicle is
dependent on FSH and LH.
What is spermatogenesis? - correct answer ✔✔a type of cell division limited to the gametes -
formation of sperm
Where does spermatogenesis occur? - correct answer ✔✔seminiferous tubules
