reproductive Flashcards
Teste
produce sperm and testoserone
mostly done during puberty
sprem is produced in the
where in the testes specifically
seminferous tubules
Three parts of the sperm and their purpose
Head - DNA
Midpeice - mitochondira
Tail (figella) - to make the sperm move
what does it do in the reproductive sense
testosterone
-increase musculoskeletal growth
-lowering of vocal cords
-increased bone density
-increase labito
-increase anger
-increase sperm production
-increased body hair
Epididymis
-found on the upper part of the testes
-where sperm mature
Vas Deferense
tube that carries sperm from epididymis to the ejactulatory duct (superior to bladder)
Vasectomy
Vas deferense is snipped and ligated to prevent sprem from mixing with semen so a man is infertile
seminal vesicle
connects to vas deference and provided 60% of semen
-adds fructose to give sperm energy
ejaculatory duct
the tube after the seminal vesicle and vasdeferense meet that takes the semen to the prostate gland
prostate gland
-where the ejactularoty duct and prostatic urethra meet
-adds 30% of semen (citric acid, zinc, and prostate specific antigen)
bulbourethral gland
pre-ejaculate that contains an alkaline fluid that coats the urethra so the acidicity of the urethra doesn’t kill sperm
penis
3 collums of erectile tissue
superior 2 - corpus cavernosum
inferior one - spongy cavernosum
tip - glands penis (head of the penis)
prepuce - forskin
scrotum
skin around the testes
spermatic cord
contains vas deference, arteries and veins, and lymphatic and nerve tissues
uterus
made of the fundus, body, and cervix
three layers - perimetrium, myometrium, and endometrium
Fallopian Tube
-not attached to ovaries, instead has fimbriae to grab the egg and bring it into the tube
-site of fetilization
ovaries
female gonads
-ovum development
-production of estrogen and progesterone
vulva
mons pubis, clitoris, labia, vestibular bulbs/glands
cervix
-the canal from the uturus to the vagina
-where menses leave the uterus
-where a baby comes out
myometrium
-controlled by oxytocin
-thickest layer of uterus
-contracts during labor
endometrium
-sheds during menses
-serves as the cite of implantation
Ovarian cycle
follicular, ovulation, luteal
menstrual cycle
menses, proliferative, secretory, premenestal
follicular phase
days 1-14
oocyte is surrouned by a productive follice
ovulation
day 14
oocyte leaves the follicel and the ovary and is exposed to the fallopian tubes
luteal phase
days 14-28
left over follicle becomes corpus luteum
-continues to produce estrogen and progesterone to thicken endometrium in prep for pregnancy
menses
days 1-5
endometrium is shedding(period)
hormones are low
proliferative phase
days 7-14
endometrium is getting rebuilt
hormones are rising
secretory
part of menstral cycle
14-28days
continual thickening of endometrium
hormones reach a high
premestraul
days 26-28
hormones drop dramatically and causes vasoconstriction to the endometrium and causes it to shed
