Mammal repro 01
exam 1-2
Question | Answer |
---|---|
four layers of female repro tract | mucosa, submucosa, muscularis, and serosa |
mucosa | secretions for lubrication |
submucosa | supports mucosa, varied thickness, blood vessels terminate |
muscularis | outer longitudinal and inner circular muscle, contract for gamete and embryo transport and parturition |
serosa | connective tissue, support and prevents adhesions |
broad ligament layers | mesovarium, mesoalpinx, mesometrium |
mesovarium | surrounds the ovary and supports the ovary, vascular lymphatic and nerve supply to ovary |
mesoalpinx | surrounds the oviduct for support |
mesometrium | surrounds uterus for support |
layers of the ovary | germinal epithelium, tunica albuginea, cortex, and medulla |
germinal epithelium | outer single layer of cuboidal cells, continuous with peritoneum, prevents adhesions |
tunica albuginea | dense connective tissue, provides structure |
cortex | houses follicles for development |
medulla | vasculature, lymph, and nerves of the ovary |
primordial follicle | fixed at birth, single layer of squamous cells |
primary follicle | single layer cuboidal granulosa cells |
secondary follicle | >2 layers cuboidal cell, zona pellucida |
tertiary antral follicle | many cuboidal cells, antrum, zona pellucida, theca externa, and theca interna |
corpus hemmoragicum | blood vessels, granulosa, and theca cells |
corpus luteum | luteal cells, progesterone blocks myometrial contractions |
corpus albicans | scar tissue, no functions |
oviduct: infundibulum | catchers mitt, lined with fimbriae attached to capture of COC |
oviduct: ampulla | portion closest to ovary, large diameter, mucosal folds and ciliated epithelium to move oocyte to isthmus |
oviduct: isthmus | portion closest to uterus, small diameter, thick muscle that contracts to move sperm to AIJ or push embryo to uterus |
mare uterus | large uterine body, small uterine horns |
sow uterus | large, highly developed uterine horns for litter bearing |
bull uterus | small uterine horns, small uterine body |
dog and cat uterus | small uterine body, developed uterine horns |
uterus endometrium | mucosa and submucosa, uterine glands, secretions support preimplantation and embryo development |
uterus myometrium | longitudinal and circular layers of muscle |
estrogen with myometrium | uterine motility for sperm transport |
progesterone with myometrium | uterine quiescence support embryo growth |
uterus perimetrium | serosa, suport |
cervix estrogen | produce mucous for lubrication and protection from bacterial entry into the uterus |
cervix progesterone | maintenance of pregnancy by sealing the cervix with viscous mucous |
sow cervix | corkscrew like shape, digital pads |
mare cervix | folds |
cow cervix | rings |
dog and cat cervix | smooth and soft |
vestibule anatomy | portion of vagina that spans from vulva to urethra |
vestibule function | duct for urine and reproduction, stimulates penis for copulation |
