|
semen
|
sperm cells +seminal fluids
|
|
|
male reproductive organs
|
testicles
scrotum sigmoid flexure |
|
|
testicles
|
produce sperm to fertilize ova
produce testosterone |
|
|
epididymus
|
maturation and storage site for sperm cells
|
|
|
scrotum
|
contains testes
regulates temperature for sperm livability |
|
|
sigmoid flexure
|
found in bull, boar, and ram
s-shaped retractor muscle controls extension and retraction of penis |
|
|
horse penis
|
vascular
|
|
|
as semen volume goes up
|
sperm concentration goes down as
|
|
|
female role of reproduction
|
develop and release egg
permit mating conception develop embryo nourish fetus parturition lactation rebreeding |
|
|
female reproductive organs
|
ovaries
oviducts uterus cervix vagina |
|
|
ovaries
|
produce ova in follicle
produce estrogen and progesterone |
|
|
oviducts
|
site of fertilization
|
|
|
uterus
|
site for implantation of embryo
provides nutrient exchange |
|
|
cervix
|
gateway between uterus and vagina
|
|
|
vagina
|
female organ of copulation
birth canal at parturition |
|
|
estrus
|
"standing heat"
period when female is receptive to the male and mating occurs |
|
|
estrous cycle
|
time period extending from ovulation to ovulation; estrus to estrus
|
|
|
follicle
|
structure on the ovary that contains the egg
|
|
|
corpus luteum
|
structure left after follicle relases egg
|
|
|
corpus luteum develops from
|
granulosum cells
|
|
|
corpus luteum secreates
|
progesterone
|
|
|
GnRH
|
gonadotropin releasing hormone
|
|
|
GnRH is from
|
the hypothalamus
|
|
|
GnRH causes release of
|
LH and FSH
|
|
|
FSH
|
follicle stimulating hormone
|
|
|
FSH is from
|
pituitary
|
|
|
FSH stimulates
|
follicular growth and development
|
|
|
LH
|
lutenizing hormone
|
|
|
LH is secreated from
|
pituitary
|
|
|
LH causes
|
ovulation
|
|
|
LH is important for development and function of
|
corpus lutiem relationship with LH
|
|
|
estrogen is from
|
from ovarian follocles
|
|
|
promotes growth and development of uterus
|
estrogen promotes
|
|
|
responsible for estrous behavior
|
estogen
|
|
|
triggers LH release
|
estrogen
|
|
|
from CL
|
progesterone
|
|
|
hormone that maintains pregnancy
|
progesterone
|
|
|
how progesterone maintains pregnancy
|
blocks follicular development and onset of estrus
keeps hypothalamus from releasing GnRH |
|
|
no GnRH
|
no FSH is result of
|
|
|
no FSH
|
no estrogen is result of
|
|
|
no estrogen
|
no LH as result of
|
|
|
from uterus due to atrophy of the egg
|
prostaglandin is from
|
|
|
causes CL to regress
|
prostaglandin effect on CL
|
|
|
ovulation pathway
|
CL regresses; progesterone decreases and releases hypothalamic block ; GnRH is produced; FSH is produced; estrogen is produced; causes surge of LH which causes ovulation
|
|
|
structure within the ovary contains the egg
|
follicle
|
|
|
follicle develops in response to
|
FSH
|
|
|
follicle produces
|
estrogen
|
|
|
if the egg is not fertilized
|
prostaglandin is released from uterus
|
