PELVIC ORGANS Flashcards
hollow muscolomembranous organ; located between symphonies pubis and vagina; ureters insert at the inferior portion (trigone)
bladder
7 to 10 cm canal of smooth muscle extending from the external vaginal intuits to the uterine cervix
vagina
surrounds the anterior aspect of the external cervix and is smaller than the posterior fornix
anterior fornix
surrounds the posterior aspect of the external cervix; it is a frequent site of vaginal fluid collections due to gravity
posterior fornix
sound the lateral aspects of the external cervix on either side
lateral fornix
pear shaped, hollow organ located between urinary bladder and rectum
uterus
upper expanded portion of the uterus between the fallopian tube
fundus or dome
main portion of the uterus
body or corpus
area between body and cervix; which is also referred to the lower uterine segment; the most flexible portion of the uterus and grows at the most rapid rate during pregnancy
isthmus
cylindrical projection into the vagina which provides an alkaline secretion favorable for sperm penetration and acts as a sphincter during pregnancy
cervix
continuation of the endometrial cavity into the cervix
endocervical canal
opening form the cervix into the uterus
internal os
opening form the cervix into the vagina
external os
outer serosal layer which part of the visceral peritoneum; laterally is becomes broad ligament; anteriorly it forms anterior and posterior cul de sac
perimetrium
middle muscular layer, which is composed of three layers of smooth muscles which contract during parturition; homogenous appearance
myometrium
inner mucous layer which consists of the superficial functional layer and deeper permanent basal layer
endometrium
tissues surrounding the uterus and does not construe a uterine layer
parametrium
forward placement of the uterus at the cervix (forming 90 degree angle with vagina)
anteversion
tilting backward of the uterus at the cervix (oriented more linearly in relationship to the vagina)
retroversion
bending forward of the uterus at the body
anteflexion
bending backwards of the uterus at the body; may become incarcerated during pregnancy - symptom is urinary retention
retroflexion
outer functional layer; constitutes the bulb of the ovarian substance and contains a large number of primordial and developing follicles
cortex
inner ovary which contains blood vessels and connective tissue
medulla
7 to 14 cm in length and function to transport the fertilized ovum to uterus by means of peristaltic contractions
fallopian tube
narrow and relatively straight; located within uterine wall
interstitial/intramural
medial portion closest to uterus
isthmus
longest portion; curves around the ovary; thin walled and distendable; normally site of fertilization
ampulla
outer trumpet shaped end (distal)
infundibulum
numerous fingerlike projections which maintain a close relationship between the tube and ovary
fimbriae
located between the pubic bone and the anterior urinary bladder wall; rarely fluid is seen in this space, but masses in the space with displace the urinary bladder posteriorly
space of Retzius
located anterior to the uterus and posterior to the urinary bladder; this space is usually empty but may contain loop of bowel
vesicouterine space (anterior cul-de-sac)
located posterior to the uterine cervix and anterior to the rectum; this is the most dependent recess in the body and therefore the most common site for free peritoneal fluid to collect
rectouterine space (posterior cul-de-sac or pouch of Douglas)
