1.1 Female Repro Organs Flashcards
layers and their functions - female internal gentialia
serosa - cover and containment
muscuarlis - contraction (Transport of gametes & parturition)
Submucosa - Housekeeping & Supporting role (Nerves, blood vessels & lymphatics)
Mucosa - Secretory (Varies with region)
Oviduct components and functions
infundibulum - contains fimbriae to cellect egg from ovary
apulla - >1/2 oviduct length, fern-like mucosal folds; site for fertlization
isthmus - connects to uterus; uterotubal junction; physical barrier helping to prevent polyspermy
type of uterus in our common domestic species
bicornuate
uterine layers
Perimetrium: Serosa
Myometrium: Muscularis
Endometrium: Mucosa + Submucosa
metritis vs endometritis
Metritis: Inflammation of endometrium, underlying glandular tissues and the muscular layer.
Endometritis: Inflammation of the endometrium and underlying glandular tissue
5 primary functions of the uterus
- transport and storage of sperm
- luteolysis and control of cyclicity
- environment for pre-attachment of embryos
- maternal-fetal interactions through placenta
- expulsion of the fetus and fetal placenta
what species have cervical rings?
cow, ewe, sow
surface of cervix has what microscopic features of its surface and cells?
- many crypts and folds covered with columnar epithelium
-some cells are ciliated, others produce mucin-containing protein
what does the mare have instead of cervical rings?
longitudinal cervical folds
what special feature does the sow cervix have?
interdigitating prominences
what does the cervix produce during estrous?
mucus that lubricates the vagina during copulation.
what role does the cervix play in removing foreign material introduced during copulation?
foreign material (and some sperm) are flushed out by cervical mucus
how does the cervix alter sperm numbers?
reduces via acidity
what happens to the cervix during pregnancy?
seals up to isolates conceptus from external environment
what does the cervix protect against in non-pregnant animals?
bacterial and fungal infections
what is the fornix? where and in what species do we find it?
-in cow and mare, cervix protrudes into the anterior vagina forming this pocket
how does the mucosal surface of the cranial and caudal vagina differ?
caudal - stratified squamous epithelium
cranial - columnar epithelium
what is the vulva? what is the commissure? what structure does it contain?
-vulva is the external part of the female repro tract
-major and minor labia meet in the medial part to form the commisure
-ventral commisure houses the clitoris fossa and clitoris
how is transport of hormones between reproductive organs acheived?
counter-current transport - close apposition of blood vessels and lymphatics
