Reproduction System Flashcards
What hormone do testes produce?
testosterone
what hormone do ovaries produce?
estrogen
when do testes and ovaries begin to develop?
in the 7th week of development
what is puberty?
the development of the reproduction systems, able to reproduce. the start of producing active reproductive cells.
do male and female reproduction organs from the same tissues in the embryos?
yes.
what does the hypothalamus do to begin puberty?
signals to the pituitary gland to produce and release increase levels of FSH and LH.
What does FSH and LH do in the male reproductive system?
Stimulates the production of testosterone.
what does FSH and testosterone do?
they are the cause of the development of sperm.
where do the testes develop?
in the abdominal cavity and drop in the scrotum before birth.
what is needed for proper sperm production?
lower temp, which is why they are on the outside of the body.
what produces sperm?
the seminiferous tubules, which are found in the testes.
in which process is sperm developed in?
sperm is created through the process of meiosis.
what are the tree parts of the sperm?
the head (nucleus), the mid-piece(mitochondria) and the tail (flagellum)
where do sperm move after being produced in the seminiferous tubules?
moved to the epididymis to fully develop.
what does the vas deferens do?
connects to the epididymis and merges with the urethra. then sperm is able to be released to the outside of the body.
what are the 3 glands that line the males reproductive tract?
seminal vesicle, prostate, Bulbourethral
what are the male reproductive tract glands responsible for?
producing seminal fluid.
what are the 2 roles of the seminal fluid?
nourish the sperm and protect the sperm against the acidity of the female reproductive system.
sperm + seminal fluid =
Semen
how does the penis get ready for sperm delivery?
the contraction of muscles.
what does FSH do in the female reproductive system?
simulates the ovaries to produce estrogen.
what id the main job of the female reproductive system?
produce ova (eggs) and to prepare the body to nourish the development of the embryo.
how many primary follicles are in each ovary
400 000.
what are follicles?
clusters of cells surrounding an egg.
women are born with thousands of immature eggs (primary follicles) but how many will be released?
about 400 eggs will end up being released.
what happens to the follicle under the influence of FSH?
the follicle becomes larger and completes meiotic cell division.
what does meiotic cell division do?
creates one large egg and 3 polar bodies.
what happens when the follicle has completely matured?
the egg that was surrounded by the follicle is released and swept from the ovary into fallopian tube.
what helps the egg to move through the fallopian tube?
cilia
