5 Clinical anatomy, female repro: uterine tubes (workbook) Flashcards
what is the uterine tube?
muscular tube, narrow medially
funnel-shaped abdominal opening (near ovary)
what is the abdominal opening of the uterine tube called?
ostium
what is the fimbria?
margins of ostium
finger-like projections
what is the fimbria an extension of?
the infundibulum
what does the infundibulum continue to become?
continues medially into an expanded intermediate segment - the ampulla
what does the fallopian tube open to?
opens into the uterine cavity (through narrow isthmus)
function of fallopian tube?
transfer + transport ovum from ovary –> uterine tube –> uterus
histologically, what does the walls of the fallopian tubes consist of?
mucous membrane (mucosa), muscular layer (MM), serous coat (serosa)
how is the mucous membrane organised in the fallopian tubes?
thrown into complex folds
lumen appears as labyrinthine system of narrow spaces (maze like)
what is the epithelium lining of the mucous membrane of fallopian tubes?
simple columnar type
consists of ciliated + non-ciliated (secretory) cells (secrete mucous secretion to help ovum + sperm travel)
where does the fimbria move?
over the surface of the ovary
what do fimbria and ciliated cells lining the mucous membrane function to do?
assist in transfer of ovum from surface of ovary into uterine tube
(peritoneum to uterine cavity - spread of infection: peritonitis)
function of secretory cells of the mucous membrane of fallopian tubes?
provide nutrients to early conceptus following fertilisation
what does contraction of the SM layer of the fallopian tube assit in?
transport of sperm to site of fertilisation (ampulla)
transport of conceptus to uterus (from fallopian tube)
what is salpingitis?
inflammation of the uterine tube, caused by microorganisms
