(Workbook page 109)Internal GenitaliaThe vagina leads from the introitus (its external opening) to the cervical portion of the uterus. The uterus is the hollow, muscular organ in which a fertilized ovum develops. The uterine walls have three layers: the endometrium (lining), myometrium (muscular layer), and perimetrium (outer covering, which is continuous with the pelvic peritoneum). The endometrium proliferates (thickens) and sloughs off in response to cyclic hormonal changes. The cervix is the narrow,
lower portion of the uterus that opens into the vagina. The two fallopian tubes extend from the uterus to the ovaries. Their function is to conduct ova from the spaces around the ovaries to the uterus. Fertilization normally occurs in the distal third of the fallopian tubes. From puberty to menopause, the ovaries are the site of (1) ovum maturation and release and (2) production of female sex (estrogen and progesterone) and male (androgens) hormones. Female Sex HormonesFemale sex hormones predominate and are involved in sexual differentiation and development, the menstrual cycle, pregnancy, and lactation. Androgens in women contribute to prepubertal growth spurt, pubic and axillary hair growth, and activation of sebaceous glands. Developing ovarian follicles (structures that enclose the ovum) produce estrogen (primarily estradiol). The corpus luteum, the structure that develops from the ruptured ovarian follicle after ovulation or
