Vocabulary: Menstrual cycle & Reproductive system concerns Flashcards
The first menstruation
Menarche
Transitional stage between childhood and sexual maturity
Puberty
Transitional phase during which ovarian function and hormone production decline
Climacteric
The last menstrual period dated with certainty once 1 year has passed after menstruation ceases
Menopause
Period preceding the last menstrual period that lasts about 4 years; during this time ovarian function declines, ova diminish, more menstrual cycles become anovulatory, and irregular bleeding occurs
Perimenopause
Periodic uterine bleeding that begins approximately 14 days after ovulation and lasts an average of 5 days
Menstruation
The cycle that involves cyclic changes in the lining of the uterus
Endometrial cycle
Phase of the menstrual cycle during which the uterine lining grows rapidly and thickens from about the 5th day to the time of ovulation
Proliferative phase
Phase of the menstrual cycle during which the uterine lining becomes luxuriant with blood and glandular secretions suitable to protect and nurture a fertilized ovum
Secretory phase
Phase during which the blood supply to the functional uterine lining is blocked and necrosis develops; the functional layer separates from the basal layer and menstrual bleeding begins
Ischemic phase
Cycle that involves secretion of hormones required to stimulate ovulation
Hypothalamic-pituitary cycle
Cycle that involves the changes in the ovary, leading to ovulation. It consists of 2 phases: Follicular and luteal
Ovarian cycle
Structure that encloses the developing ovum; it ruptures at the time of ovulation, releasing the ovum
Graafian follicle
Hormone secrete by the hypothalamus when ovarian hormones are reduced to a low level. It stimulates the pituitary gland to secrete 2 critical hormones
Gonadotropin-releasing hormone (GnRH)
Pituitary hormone that stimulates the development of follicles in the ovary
Follicle-stimulating hormone (FSH)
Pituitary hormone that stimulates the expulsion of the ovum from the graafian follicle and formation of the corpus luteum
Luteinizing hormone (LH)
Ovarian hormone that stimulates the thickening of the endometrium that occurs after menstruation and prior to ovulation; it is also responsible for changes in the cervix and cervical mucus
Estrogen
Stretchable quality of the cervial mucus at the time of ovulation
Spinnbarkeit
Ovarian hormone that is responsible for the changes in the endometrium that occur after ovulation to facilitate implantation should fertilization occur; it is also responsible for the rise in temp that occurs after ovulation
Progesterone
Oxygenated fatty acids classifies as hormones. They are thought to play an essential role in ovulation, transport of sperm, regression of the corpus lute, and menstruation. By increasing the myometrial response to oxytocin, they also play a role in labor and dysmenorrhea
Prostaglandins
Absence of menstrual flow; clinical symptom of a variety of disorders but most commonly a result of pregnancy and is a classic sign of anorexia nervosa
Ammenorrhea
Absence of menstrual flow r/t problem of the central hypothalamic pituitary axis
Hypogonadortopic ammenorrhea
Interrelatedness of disordered eating, amenorrhea, and altered bone mineral density
Female athlete triad
Collective term used to describe pain and discomfort associated with the menstrual cycle. The 3 main conditions are dysmenorrhea, PMS, and PMDD
Cyclin Premature pain and discomfort
