Ch 39 Introduction To The Reprodutive System Flashcards
Andropause
Decrease in gonadal function in males associated with advancing age, analogous female menopause
Corpus luteum
Remains of a follicle that releases mature ovum at ovulation; becomes an endocrine gland producing estrogen and progesterone
Estrogen
Hormone produced by the ovaries, placenta, and adrenal gland; stimulates development of female characteristics and prepares the body for pregnancy
Follicle
Storage site of each ovum in the ovary; allows the ovum to grow and develop; produces estrogen and progesterone
Inhibin
Estrogen like substance produced by seminiferous tubules during sperm production; acts as a negative feedback stimulus to decrease release of follicle-stimulating hormone (FSH)
Interstitial or Leydig cells
Part of the testes that produce testosterone in response to stimulation by Luteinizing hormone (LH)
Menarche
The onset of the menstrual cycle
Menopause
Depletion of the female ova; results in lack of estrogen and progesterone
Menstrual cycle
Cycling of female sex hormones in interaction with the hypothalamus and anterior pituitary feedback systems
Menstruation
Expulsion of the uterine lining occurring approximately every 28 to 32 days
Ova
Eggs, the female gamete, contain half of the information needed in a human nucleus
Ovaries
Female sexual glands that store ova and produce estrogen and progesterone
Ovulation
Release of the ovum from the follicle into the abdomen
Progesterone
Hormone produced by the ovaries, placenta, and adrenal gland; promotes maintenance of pregnancy
Puberty
 point at which the hypothalamus starts releasing gonadotropin releasing factor (GnRF) To stimulate the release FSH and LH and begin sexual development
