Cervix Flashcards
cervical gland secretion not during ovulation
mostly water mucus that facilitates entry of sperm into uterus at ovulation
under control of estrogen
cervical gland secretion during pregnancy
viscous mucus to prevent entry of sperm and other microorganisms during pregnancy and other parts of the cycle
structure of cervix
mucosa = simple columnar
- lamina propria = more fibrous than cellular –> important when talking about pregnancy
- branched, tubular glands (mucus)
muscularis = dense collagenous CT with elastic and SmM fibers
mucosa = mixed columnar with with stratified squamous epithelium
- continuous with uterine columnar epithelium at the top; transitions to non kerantized startified as cervix opens to vagina at bottom (transitional zone)
- where cervical glands are located (simple columnar)
Nabothian cysts
caused if cervical mucus gets stuck
PAP smear
swabbing of transition zone to look at stratified squamous epithelial cells and see if there is any hint of cervical cancer
hormonaly regulation of cervix
estradiol = stimulates formation of watery mucus (lysozyme)
progesterone = induces formation of a very viscous mucus
- stop more sperm from entering
relaxin = stimulates softening of the cervix by lysis of collagen fibers at the time of parturition, produced by coprus luteum and placenta
