Reproduction System Flashcards
cell division, reproductive
meiosis
genetic material
chromosomes
twice the chromosomes
diploid
half the chromosomes
haploid
process of production of sperm that takes place in tubules
spermatogenesis
male sex hormones
androgens
connective tissue that attaches tested to scrotum
gubernaculum
daughter cells, half # of chromosomes
mitosis
process where ova are produced in ovaries
oogenesis
male gonads
testes
houses the testes and regulated body temp
scrotum
principle androgen or male hormone
testosterone
3 parts of the sperm
head- covered by caplike acrosome, helps penetrate
midpiece- provides energy
tail- flagellum/ movement
development of testes
- develops in abdomen
- gradually pulls down
- passes through inguinal rings down to scrotum
adjusts position of tested depending on temp, attached to scrotum
cremaster muscles
links testes with rest of body
spermatic cords
meshwork of tiny veins surrounding artery
pampiniform plexus
visceral vaginal tunic
AKA proper
parietal vaginal tunic
AKA common
castration
orchiectomy
fibrous connective tissue capsule that encloses each tested
tunica albuginea
divides each testes into tiny lobules
septa
sertoli cells
shields form body’s own immune system
epididymis
storge and maturation site
vas deferens
tube of transportation
spermozoa mixed with secretions from accessory glands
semen
duct of glands
enter pelvic portion of urethra
produce fluid to counteract acidity of female reproductive tract
accessory reproductive glands
dogs only have this reproductive gland
prostate glands
bulbourehtral glands
AKA cowper’s glands
lubricates urethra for passage of sperm
bulbourethral glands
horse penis
mushroom shaped, well defined
runimant penis
small, not well defined
cats penis
spines on penis
encloses penis
prepuce
s-shaped curve of non erect penis
sigmoid flexure
tip of uterine horn caudally to inguinal ring
round ligament of uters
female hormones
estrogen and progestins
dorsal part of abdomen, almond shaped
ovaries
horses ovaries
indented, bean shaped
sow ovaries
cluster of ovaries
estrus vs. estrous
heat cycle vs. entire cycle
gamete released into oviduct
ovum
empty follicle fills with blood
corpus hemorrhagicum
corpus luteum
produces progesterone
induced ovulators (after breeding)
cats, camels, rabbits, ferrets
fimbriae
finger-like project help move and store eggs
simple columnar epithelium cells, inner layer
endometrium
thickest, smooth muscle projection & expel fetus
myometrium
outermost, covered by visceral layer of peritoneum
perimetrium
diestrus
dogs
monoestrous
foxes, minx
proestus
developing follicle
metestrus
after ovulation
diestrus
back into heat, preg- embryo develop
anestrus
temporary, mature phase
