| The erectile tissue that surrounds the urethra is the | Corpus spongiosum |
| The erectile tissue that is located on the anterior surface of the the flaccid penis is the | Corpora cavernosa |
| The scrotum is | The fleshy pouch suspended below the perinuem and anterior to the anus |
| The role of the pituitary hormone follicle stimulating hormone in males is to | Initiate sperm production in testes |
| The pituitary hormone that stimulates the interstitial cells to secrete testosterone is | LH |
| The broad ligament is | And extensive messentary that encloses the ovaries and uterine tubes and uterus |
| The structure that transports the ovum to the uterus is the | Uterine tube |
| The organ that provides mechanical protection and nutritional support for the developing embryo is the | Uterus |
| The round ligaments extend from the | Lateral margins of the uterus through inguinal Canal to the base of the genitals |
| The inferior portion of the uterus that projects into the vagina is the | Cervix |
| The muscular layer of the uterus is the | Myometrium |
| Each of the following statements concerning the oogenesis is true except that | Oogenesis occurs continuously from puberty until menopause |
| A surgen in luteinizing hormone that occurs during the middle of the ovarian cycle triggers | Ovulation |
| A rise in the blood levels of the follicle stimulating hormone at the beginning of the ovarian cycle is responsible for | Follicle maturation |
| The average length of the menstrual cycle is | 28 days |
| During the proliferative phase of the menstrual cycle | A new functional layer is formed in the uterus |
| During the secretory phase of the menstrual cycle | Glands and large and accelerate their rates of secretion |
| During the menses | The old functional layer is sloughef off |
| All of the following are true of the vagina except that it | Loses a portion of its lining during menstrual flow |
| The vagina is | A muscular tube extending between the uterus and external genitalia |
| The vulva includes all of the following except being | Fornix |
| In the mammary gland milk production occurs in the | Lobules |
| The central space bounded by the labia minora is the | Vestibule |
| Fleshy folds that encircle and particularly concealed the labia minora and vestibular structures is the | Labia majora |
| The clitoris is | A Mass of erectile tissue located at the anterior margin of labia minora |
| The generally dark pigmented skin that surrounds the nipple is the | Areola |
| The principal hormone secreted by the corpus luteum is | Progesterone |
| menstruation is triggered by a drop in the level of | Estrogen and progesterone |
| The developing a follicle cells secrete | Estrogen |
| The hormone estradiol does all the following except that it | Stimulates the symptoms of menopause |
| Emission | Begins with peristaltic contractions of the ampulla |
| Contractions of the ischiocavernosus and bulbocavernousus muscles result in | Ejaculation |
| For erection and ejaculation to occur | There must be sufficient blood hydrostatic pressure and parasympathetic |
| All the following occur at puberty in both sexes except that | Levels of FSH rise while levels of LH lower |
| At menopause all of the following occur except that | Ovaries swell |
| During the male climacteric | FSH and LH levels rise |
