Reproduction Flashcards
what is the development process of sperm cells
1 - spermatogonium (2n)
2 - primary spermatocyte (2n)
3 - secondary spermatocyte (n)
4 - spermatid (n)
5 - sperm cell (n)
where does sperm mature
seminiferous tubules
what hormones are involved in sperm production during puberty
gonadotrophin-releasing hormone (GnRH)
lutenizing hormone (LH)
follicle stimulating hormone (FSH)
where is testosterone produced
leydig cells
what is the role of testosterone
controls growth, development and maintenance of sex organs
stimulates bone growth
protein anabolism
sperm maturation
what is the name of the sperm head covering
acrosome
what are the functions of the male reproductive system
1 - testes produce sperm and testosterone
2 - ducts transport store and assist in sperm maturation
3 - accessory glands secrete liquid semen
4 - penis contains urethra for ejaculation
where is the normal site of fertilization
fallopian tubes
what are mammary glands
modified sudoriferous glands that produce milk
What are the functions of the female reproductive system
1 - ovaries produce secondary oocytes and hormones
2 - uterine tubes transport secondary oocyte to uterus
3 - uterus is site of implantation and development of fetus
4 - vagina receives penis during intercourse and is a passageway for birth
5 - mammary glands secret milk
what is the role of estrogen
stimulate growth, development and maintenance of female reproductive structures
development of secondary sex characteristics
protein synthesis
what is the role of progesterone
prepares endometrium for implantation
prepares mammary glands for milk synthesis
what is the role of relaxin
increases flexibility of pubic area to dilate cervix during delivery
