reproductive system Flashcards
uterine tube/fallopian tubes
receives ovum fr ovary move to uterus
site fertilization
ovarian follicles and development
primordial follicle - has primary oocyte, one layer follicle cells
primary follicle - follicle cells surround oocyte, secrete estrogen
secondary follicle - wall become thicker, fluid appear
tertiary follicle - graafian follicle, fluid fuse and form bigger
ovulation - follicle rupture, secondary oocyte leave
corpus luteum - secrete progesterone, and die if no fertilization
corpus albicans - scar tissue of whats left over
oogenesis
oogonium
primary oocyte (diploid 46 chromo)
secondary oocyte (haploid 23 chromo)
zygote (46 chromo) only if fertilized
fimbrae
connect fallopian tube to ovary
finger like protrusion to “catch” ovum and move it
how long does it take for sperm to mature
10-15 days
pathway of spermatogenesis
seminiferous tubules
epididymis
vas deferens
prostate gland
bulbourethral
seminal vesicle
prostatic duct
urethra
corpora cavernosa vs corpus spongiosum
cavernosa - around spongiosum, cause erection
spongiosum - around urethra, fill w blood for erection
spermatogenesis
sermatogonium
primary spermatocyte
secondary spermatocyte
spermatid
sperm(spermatoza)
follicle stimulation hormone
involved in maturation of sperm and ovum
produced by anterior pituitary gland
luteinizing hormone
stimulate ovulation and production of testosterone
produced by anterior pituitary gland
seminiferous tublule
highly coiled tube
sperm produced in the walls
tunica albuginea vs tunica vaginalis
albuginea - around testis, white in color
vaginalis - encase testis and epididymis, 2 layers
rete testis
tubes collect fr seminiferous and move to efferent ductile to epididymis
epididymis
where sperm mature
accessory ducts/glands
seminal vesicle - secrete 60% semen volume, neutralize urethra
prostate gland - secretes 20-30% semen, release nutrients for sperm
bulbourethral - (cowper’s) neutralize urethra,
