Gamete production and fertilisation Flashcards
(18 cards)
Where are sperm produced
in the testes in the seminiferous tubulues
What produces the hormone testosterone
interstitial cells of the testesW
What do the interstitial cells of the testes produce
testosterone
What is the function of the prostate gland and seminal vesicles
Secrete fluids that maintain the mobility and viability of the sperm
What do ovaries contain
inmature eggs in various stages of development
What is each egg surrounded by
a follicle
What do follicles do
protects the developing ovum and secretes hormones
What occurs during fertilisation
mature ova are released into the oviduct where they may be fertilised by sperm to form a zygote
What happens during ovulation
the mature ova are released into the oviduct
After ovulation What dies the empty follicle form
The corpus luteum
Which hormone is released from the ovary and repairs the uterine lining
oestrogen
Which hormone is released from the ovary and maintains the uterine lining
progesterone
Explain why men show continuous fertility.
they continuously produce sperm
What is the function of the sperm duct
Carry sperm to urethra
What is the pathway for the ova if no fertilisation occurs
Oviduct - uterus - vagina
What is the pathway for the ova if fertilisation does occur
Oviduct - uterus - endometrium
What prevents further follicles from developing
the negative feedback effect of the ovarian hormones on the pituitary gland and the secretion of FSH and LH
How is ovulation stimulated
drugs that prevent the negative feedback effect of oestrogen on FSH secretion
