F+M reproductive parts and main hormones Flashcards
testes
produce sperm cells
seminiferous tubules
produce immature sperm cells
epididymis
matures and stores sperm cells in coiled tubules
vas deferens
carries sperm from the epididymis to its junction with the urethra
seminal vesicle
secretes fructose into semen to provide energy for the sperm
prostate gland
secretes an alkaline buffer into the semen to protect sperm from acidic vagina
cowper’s gland
secretes mucus rich fluids into the semen that may protect sperm from acids in the urethra
urethra
carries semen during ejaculation and carries urine from the bladder to the exterior of the body
penis
deposits sperm into the female reproductive system during ejaculation and contains the urethra
interstitial cell
where testosterone is produced, found in the testes surrounding the seminiferous tubules
Testosterone
produced by interstitial cells, stimulates spermatogenesis, promotes and regulates the development of secondary sexual characteristics, associated with sex drive
follicle stimulating hormone (FSH)
MALE
produced by anterior pituitary gland, stimulates the production of sperm cells in the seminiferous tubules
Luteinizing hormone (LH)
MALE
produced by the anterior pituitary gland, promotes the production of testosterone by the interstitial cells
gonadotropic releasing hormone
produced by hypothalamus, stimulates the secretion of FSH and LH
ovaries
produce estrogen and progesterone, site of ovum development and ovulation
fallopian tubes (oviducts)
carries the ovum from the ovary to the uterus, site of fertilization
fimbriae
sweep the ovum into the fallopian tube following ovulation
Uterus
organ where embryo and fetus develop, involved in menstration
cervix
separates the vagina from the uterus, holds the fetus in place during pregnancy, dilates during birth to allow the fetus to leave the uterus
vagina
extends from the cervix to the external environment, provides a passageway for sperm and menstrual flow, functions as the birth canal
estrogen
produced by follicle cells (in ovary), inhibits growth of facial hair and initiates secondary sexual characteristics, and causes the thickening of the endometrium
progesterone
produced by the corpus luteum (in ovary), inhibits ovulation, inhibits uterine contractions, firms the cervix, and stimulates the endometrium
follicle stimulating hormone (FSH)
FEMALE
secreted by anterior pituitary gland, stimulates the development of the follicle cells in the ovary
Luteinizing Hormone (LH)
FEMALE
secreted from anterior pituitary gland, stimulates ovulation and the formation and maintenance of the corpus luteum
