Lecture female reproductive system
Terms in this set (56)
Produce eggs, receive sperm; provide a place and nutrition for the fetus; ability to give birth and nourish young; compared to male: produce and deliver sperm.
Functions of female reproductive system
Primary sex organs. Closely associated with Fallopian tubes and uterus. Held in place by folds of peritoneum (ligaments)
Thick, muscular chamber. Opens to vagina. Site of fetal development; mechanical protection, nutritional support, waste removal.
Broad ligament over the uterus
Broad ligament over the ovary
Connects ovary to uterus. Tough connective tissue.
Round ligament of the uterus
Runs along top of broad ligament, female analogue of spermatic cord, maintenance of the anteversion of the uterus
Suspensory ligament of the ovary
Ovarian end of broad ligament attached to body wall in area of last rib, ovarian artery and vein inside.
Bends anteriorly over bladder. 80% of woman
Bends posteriorly, smaller. 20% of woman. Not a problem, not any harder to get prego. Some point during pregnancy will shift anteriorly.
Space between bladder and uterus.
Space between rectum and uterus.
Ovaries covered in
Production of oocytes
Mature female sex cells
Oocytes located within fluid- filled bubbles called ___________. These produce estrogen.
Follicle ruptures and oocyte is released to body cavity, destined for uterine tube
After ovulation, remaining follicle cells form _____ _____ which produces progesterone: prepare the uterus for pregnancy. Degenerates if no pregnancy occurs.
Scar tissue, remnant of degenerated corpus luteum.
A fluid- filled sac that develops within the ovary
Occurs when a follicle fails to rupture.
Passageways that carry eggs away from the ovaries; where fertilization occurs; secretes nutrients to nourish sperm and embryo
Wide lateral end of Fallopian tubes
Fingerlike extensions that help catch egg of Fallopian tubes
Middle part of Fallopian tubes
Part of Fallopian tubes connected to uterus
Smooth muscle: peristalsis. Epithelium with cilia
Movement of egg in Fallopian tubes
Fertilized egg implants outside of uterus (usually in Fallopian tubes). 1 in 300 pregnancies. Risk of tube rupture at about 12 weeks. Extremely dangerous to mother: risk of hemorrhaging (severe bleeding)
The widest and most superior portion of the uterus.
Space within the body of the uterus, "lumen" of the uterus
Transition point between the body of the uterus and the cervix
Narrow passage through the cervix
The opening to the uterus
Thick outer muscular layer of uterine wall, contractions of muscle cause cramps to push out endometrium
Thin inner glandular layer of uterine wall, variable width depending on stage of menstrual cycle
What happens if female pelvic floor muscles weaken ex. after childbirth?
Uterus balls into vagina, cervix is right at entrance to vagina. More likely to occur the more you give birth. Surgical procedures to put uterus back in place and mesh to repair floors.
Muscular canal, pierces through pelvic floor muscles and perineal membrane.
Vagina contains ______ _______.
Vagina opens into the _______
Centrail space in external genitalia containing labia minora, urethral opening, vaginal orifice.
Smaller pair of skin folds that protect the vaginal opening
Opening through which urine leaves the body
Analogous to male glans of penis. Covered by hood (prepuce)
Prepuce of clitoris
Rounded elevated portion of fatty tissue prominence over symphysis pubis, covered with hair.
The larger outer folds of the vulva.
Bulb of the vestibule
Homologous to the bulb of penis and adjoining part corpus spongiosum male, consist two elongated masses erectile tissue, placed one on either side vaginal orifice
Female erectile bodies equivalent to male erectile body. There are analogous structures. May be smaller and shaped differently, but same thing happens.
Female erectile tissue
Analogous to prostate, secretes into urethra, may contribute to "G-spot"
Analogous to bulbouretheral, secrete lubrication into vestibule
Heads wider. We need narrow pelvis because we're bipeds. During child birth, infant must pass through pelvis.
Why is it difficult for humans to give birth?
Sacral promontory, arcuate line, pubic bones
ischiopubic ramus, ischial spines, sacrum
