NUR 611 Assignment 12.1: Workbook Assignment – Ryan Kent Chapter 23 1. (from pg. 109 of the study guide) Concept: What is the mons pubis and the labia majora?Mons pubis 2. (from pg. 110 of the study guide) Concept: Where do female sex hormones come from? The sex hormones are all steroid hormones and are synthesized from cholesterol (see Chapter 21). Male and female sex hormones are present in all adults. However, the female body contains low levels of testosterone and other androgens, and the male body contains low levels of estrogen. Individual effects of sex hormones depend on their amount and concentration in the blood. The dominant female sex hormones, estrogen and progesterone, are produced primarily by the ovaries. During fetal development, infancy, and childhood, sex hormone production is low. At puberty hormone production surges, triggering sexual maturation and development of secondary sex characteristics. From puberty to menopause, the sex hormones control the menstrual cycle and are produced cyclically, that is, production surges and diminishes monthly, creating the ovarian and uterine changes associated with the menstrual cycle. These hormones also are produced in higher levels during pregnancy by the placenta, inhibiting ovulation. Androgens are produced in small amounts by the ovaries and the adrenals and have important functions in women. (referenced from pg. 776 of the textbook) 3. (from pg. 110 of the study guide) Concept: What are estrogens and estradiol? Estrogen is a generic term for three similar hormones: estradiol, estrone, and estriol. Estradiol (E2) is the most potent and plentiful of the three and is principally produced (95%) by the ovaries (ovarian follicle and corpus luteum). Androgens are converted to estrone in the ovary and peripheral adipose tissue. Estriol is the peripheral metabolite of estrone and estradiol. Estrogen has numerous biologic effects, many of which involve interactions with other hormones, and is needed for maturation of reproductive organs,
