scrotum
sac of skin that protects the testis
testicles
where sperm is produced w interstitial cells
what are sperm aided by
sertoli cells
epididymis
where sperm go to mature
vas deferens
2 tubes that carry mature sperm to the urethra
vasectomy
where u tie off the 'vas deferens'
seminal fluid
secretions made by 3 exocrine glands
seminal fluid + sperm =
semen
seminal vessicles
produces fructose/prostaglandins
prostaglandins
have local effects/initiate smooth muscle contraction
fructose
helps the sperm cell have energy
prostate gland
produces an alkaline buffer against acidity (vagina)
PNS permits
erection
sympathetic nervous system permits
muscles to contract / orgasm
primary sex charateristics
repro structures that develop in utero and present at birth
what chromosome marks u a male
y chromosome
secondary sex charateristics
begin developing at puberty
puberty influences what hormone (males)
testosterone
what cna cause infertility
incorrect hormone levels/injury/blocked vas deferens/durgs/impotence
sperm structure
head, midpiece, tail
whats in the head of the sperm
acrosome, nucleus
what does the acrosome do
a hard cap on the sperms head to break through the egg
midpiece includes what
mitochondria
another word for tail
flagellum
the order for meiosis for sperm
spermatogonia (stem cells) - primary spermatocytes - secondary spermatocytes - spermatid - mature sperm
where is spermatogonia found
edge of seminifourous tubules
another statement for development of sperm
process of meiosis
in meiosis the chromosome is
being halved 46 - 23
how many PRIMARY spermatocyte is there
one
the primary spermatocytes divides into what
four
primary spermatocytes have how many chromosomes
46
2 secondary spermatocytes have how many chromosomes
23
4 spermatid have how many chromosomes
23
4 mature sperm have how many chromosomes
23
gamete
sex cell (egg + sperm)
meiosis is specilized to
sex cells
half chromosome #'s is also called
a HAPloid cell
ovaries
follicle makes 2 hormones (estrogen and progesterone)
fallopian tube
transports the egg from ovary to uterus fimbria sweep in the egg after its been ovulated
fertilization occurs where
fallopian tube
tubal ligation
"tubes tied" permanent birth control
uterus
where the fertilized ovum will implant and develop
2 parts of the uterus
myometrium and endometrium
myometrium
outer muscular layer lots of progesterone and oxytocin receptors
endometrium
inner nutrient-rich lining (blood) nourishes the embryo or is shed every 28 days (menstration) estrogen also causes it to grow back every month
cervix
a strong muscular band at lower end of uterus prevents fetus from entering birth canal
what is the cervix plugged with
mucus
vagina
muscular canal that connect uterus to the external environment/ acidic
primary sex charateristics (female)
repro structures that develop in utero and are present at birth (lack of y chromosome) XX
secondary sex characteristics (female)
puberty indluenced by hormones (estrogen) / thickening of endometrium maturation of vagina
