6 The broad ligament is 2 A an extensive mesentery that encloses the ovaries, uterine tubes, and uterus B a thickened fold of mesentery that supports and stabilizes the position of the ovary C a pocket formed between the posterior wall of the uterus and the anterior surface of the rectum D a structure that attaches the ovary to the wall of the uterus E a structure that extends from the lateral surface of the ovary to the pelvic wall 6 The organ that provides mechanical protection and nutritional support for the developing embryo is the 3 A vagina B uterine tube C ovary D uterus E cervix 6 The round ligaments extend from the 4 A base of the uterus and vagina to the lateral walls of the pelvis B lateral surface of the uterus to the anterior surface of the sacrum C lateral margins of the uterus, through the inguinal canal to the base of the genitals D body of the uterus to the fundus E cervix of the uterus to the vagina. 6 The muscular layer of the uterus is the 5 A endometrium B perimetrium C myometrium D uterometrium E sarcometrium 6 Each of the following statements concerning oogenesis is true, EXCEPT that 6 A at the time of birth the ovaries contain only primary oocytes B ova develop from stem cells called oogonia C an ovum will only complete meiosis if it is fertilized D oogenesis occurs continuously from puberty until menopause E the first meiotic division is completed just prior to ovulation 6 The surge in luteinizing hormone that occurs during the middle of the ovarian cycle triggers 7 A follicle maturation B menstruation C ovulation D menopause E atresia 6 A rise in the blood levels of follicle-stimulating hormone at the beginning of the ovarian cycle is responsible for 8 A follicle maturation B menstruation C ovulation D menopause E atresia 6 During the proliferative phase of the menstrual cycle, 9 A ovulation occurs B a new functional layer is formed in the uterus C secretory glands and blood vessels develop in the endometrium D the old functional layer is sloughed off E the corpus luteum is formed 7 During the secretory phase of the menstrual cycle 0 A ovulation occurs B a new uterine lining is formed C glands enlarge and accelerate their rates of secretion D the old functional layer is sloughed off E the corpus luteum is formed 7 During the menses 1 A ovulation occurs B a new uterine lining is formed C secretory glands and blood vessels develop in the endometrium D the old functional layer is sloughed of E the corpus luteum is formed 7 All of the following are true of the vagina, EXCEPT that it 2 A serves as a passageway for the elimination of menstrual fluids B receives the penis during coitus C holds spermatozoa prior to their passage to the uterus D forms the lower portion of the birth canal E loses a portion of its lining during menstrual flow 7 In the mammary gland, milk production occurs in the 3 A lobes B lobules C lactiferous duct D lactiferous sinus E lactiferous adipose tissue 7 The clitoris is 4 A a thin epithelial fold that partially or completely blocks the entrance to the vagina B a fleshy fold that encircles the vestibule C a mound of fat that is superior to the pubis D a mass of erectile tissue located at the anterior margin of the labia minora E a shallow recess that surrounds the cervical portion of the vagina 7 The principal hormone(s) secreted by the corpus luteum is/are 5
