Chapter 39 - Normal Anatomy and Physiology of the Female Pelvis Flashcards
the absence of menstruation
amenorrhea
position of the uterus when the uterine fundus bends forward toward the cervix
anteflexed
position of the uterus when the uterus is tipped slightly forward so that the cervix forms a 90-degree or smaller angle with the vaginal canal; most common uterine position
anteverted
a broad fold of peritoneum draped over the fallopian tubes, uterus, and ovaries; extends from the sides of the uterus to the sidewalls of the pelvis, dividing the pelvis from side to side and creating the vesicouterine pouch anterior to the uterus and the rectouterine pouch posteriorly; it is divided into the mesometrium, mesosalpinx, and mesovarium
broad ligament
wide band of fibromuscular tissue arising from the lateral aspects of the cervix and inserting along the lateral pelvic floor; a continuation of the broad ligament that provides rigid support for the cervix; also called the transverse cervical ligaments
cardinal ligament
one of two muscles in the pelvic diaphragm; located on the posterior pelvic floor, where it supports the coccyx
coccygeus muscles
an anatomic structure on the surface of the ovary, consisting of a spheroid of yellowish tissue that grows within the ruptured ovarian follicle after ovulation; acts as a short-lived endocrine organ that secretes progesterone to maintain the decidual layer of the endometrium should conception occur
corpus luteum
pain associated with menstruation
dysmenorrhea
a steroidal hormone secreted by the theca interna and granulosa cells of the ovarian follicle that stimulates the development of female reproductive structures and secondary sexual characteristics; promotes the growth of endometrial tissue during the proliferative phase of the menstrual cycle
estrogen
portion of the pelvis found above the brim; that portion of the abdominal cavity cradled by the iliac fossae; also called the greater or major pelvis
false pelvis
a hormone secreted by the anterior pituitary gland that stimulates the growth and maturation of graafian follicles in the ovary
follicle-stimulating hormone (FSH)
a hormonal substance that stimulates the function of the testes and the ovaries; in the female, FSH and LH are gonadotropins
gonadotropin
a hormone secreted by the hypothalamus that stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) by the anterior pituitary gland
gonadotropin-releasing hormone (GnRH)
paired triangular, flat muscles that cover the inner curved surface of the iliac fossae; they arise from the iliac fossae and join the psoas major muscles to form the lateral walls of the pelvis
iliacus muscles
a bony ridge on the inner surface of the ilium and pubic bones that divides the true and false pelvis; also called the pelvic brim or linea terminalis
iliopectineal line
one of two muscles of the pelvic diaphragm that stretch across the floor of the pelvic cavity like a hammock, supporting the pelvic organs and surrounding the urethra, vagina, and rectum; a broad, thin muscle that consists of the pubococcygeus, iliococcygeus, and puborectalis
levator ani
a hormone secreted by the anterior pituitary gland that stimulates ovulation and then induces luteinization of the ruptured follicle to form the corpus luteum
luteinizing hormone (LH)
the onset of menstruation and the commencement of cyclic menstrual function; usually occurs between 11 and 13 years of age
menarche
