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 |
