Chapter 8: The Female Cycle Flashcards
the portion of an ovarian follicle filled with liquor folliculi. Spaces formed by the confluence of small lakes of follicular liquid in the ovary
antrum (follicular)
a vascular ovarian layer characterized by polyhedral cells that secrete estrogen. The cells are developed from stromal cells, which produce steroid hormones.
theca internat
a vascular ovarian layer characterized by polyhedral cells that secrete estrogen. The cells are developed from stromal cells, which produce steroid hormones.
theca interna
steps taken to increase concentration when a level is too low
positive feedback loop
the transformation of the mature ovarian follicle into a corpus luteum
luteinization
formed in the ovary when a follicle has matured and released its egg (ovum) after ovulation. The follicle becomes the corpus luteum that produces progesterone. Progesterone causes the lining of the uterus to thicken for egg implantation
corpus luteum
a steroid hormone produced by the corpus luteum, whose function is to prepare and maintain the endometrium for the reception and development of the fertilized ovum
progesterone
absence of menstruation
amenorrhea
hormones secreted by the gonadotrope cells of the pituitary gland
gonadotropic protein
forward tipped uterus with the cervix and vaginal canal forming a 90-degree angle or less
retroverted
general term for female steroid sex hormones secreted by the ovary and responsible for female sexual characteristics
estrogen
abnormally heavy or prolonged menstruation
menorrhagia
when concentration of a hormone rises above a certain level, a series of actions take place within a system to cause the concentration to fall. Conversely steps are taken to increase concentration when the level is too low
negative feedback
painful menstruation
dysmenorrhea
abnormally light or infrequent menstruation
oligomennorhea
a peritoneum ligament extending upward from the upper pole of the ovary
suspensory (infundibulopelvic) ligament
an outer layer of a mature follicle containing spindle-shaped cells that are incapable of hormone production
theca externa
the ligament that attaches to the uterus at the level of the cervix and from the superior part of the vagina to the lateral walls of the pelvis. The cardinal ligament provides support to the uterus
cardinal ligament
a system of glands and cells the produce hormones released directly in the circulatory system
endocrine system
a uterus tilted posterior towards the rectum
anteverted
the mesentery of the uterus. It constitutes the majority of the broad ligament of the uterus, excluding only the portions adjacent to the uterine tube and ovary
mesometrium
endocrine cells located in the anterior pituitary that produce the gonadotropins; examples are follicle-stimulating hormone (FSH) and luteinizing hormone
gonadotrope cell
area in the pelvic cavity between the rectum and the uterus that is likely to accumulate free fluid; alos known as the posterior cul-de-sac and the pouch of Douglas
rectouterine recess (pouch)
uterus angled forward toward the cervix
anteflexed
hormone produced by the anterior pituitary, which stimulates ovarian follicle production in females and sperm production in males
follicle-stimulating hormone (FSH)
a backward angle of the uterine fundus in relation to the cervix
retroflexed
a mature, fully developed ovarian cyst containing the ripe ovum
Graafian follicle
outer serosal layer of the uterus, equivalent to the peritoneum
perimetrium
the ligament with a peritoneal fold that also supports the fallopian tubes, uterus, and vagina. It connects sides of the uterus to the walls and floor of the pelvis.
broad ligament
frequent irregular periods
polymenorrhea
male hormones produced in small quantities by the female ovaries and adrenal glands, with the greatest quantities occurring at the midpoint of a woman’s menstrual cycle
androgens
regulates the release of FSH and LH by gonadotropes from the anterior pituitary
gonadotropin-releasing hormone (GnRH)
