Question | Answer |
---|---|
vulva | external portion of female tract, functions for protection and holds clitoris |
vestibule | portion from vulva to urethra, functions to secrete mucous for lubrication, produce pheromones, duct for repro and urine, stimulates penis |
fornix vagina | pouch where cervix meets the vagina, common mistake in AI |
cervix | cartilaginous section between vagina and uterus |
cervix high estrogen function | secretes mucous for sperm transport and lubrication of vagina, minimizes entry of bacteria |
cervix high progesterone function | viscous mucous blocks cervical opening to seal pregnancy, prevents bacterial entry to uterus |
cervix species differences | sow: corkscrew, digital pads mare: folds cow: rings |
uterine horn | horns attached to uterus that function in sperm transport, fetal development, and placental attachment |
uterine horn species differences | cow and mare: two underdeveloped horns sow: large horns for litter bearing |
uterine bifurcation | where the uterine horns meet the uterus |
caruncle | only in ruminants, button like structures in uterine horns, function for placental attachment |
endometrial folds | folds within uterus, function to increase placental surface area in the sow and mare |
oviduct infundibulum | fimbriae on inner surface, function to capture COC for transport |
oviduct ampulla | portion closest to ovary, large diameter, mucosal folds and ciliated epithelium, function to move oocyte through oviduct |
oviduct isthmus | portion closest to uterus, large muscularis, function to contract to move sperm to AIJ, move fetus into uterus |
ovary | layers are the germinal epithelium, tunica albuginea, cortex, and medulla |
ovary germinal epithelium | outer layer for protection and prevents adhesions |
ovary tunica albuginea | dense connective tissue for support |
ovary cortex | follicular development |
ovary medulla | vasculature, lymphatics, and nerves of the ovary |
antral follicle | multiple layers of cuboidal granulosa cells, antrum, zona pellucida, theca interna, and theca externa functions to produce testosterone from theca interna, and secrete estrogen from granulosa cells |
corpus luteum | yellow body made up of luteal cells, functions to produce progesterone to block myometrial contractions and behavioral estrus |
