Write TRUE if the statement is correct, and FALSE if otherwise.** 1\) \_\_\_\_\_\_The males' testes have both an endocrine and an exocrine function. 2\) \_\_\_\_\_\_Sperm are matured and ejaculated from the epididymis and ductus (vas) deferens during ejaculation. 3\) \_\_\_\_\_\_The ejaculatory duct passes through the prostate gland. 4\) \_\_\_\_\_\_Urine and sperm are able to pass through the urethra at the same time. 5\) \_\_\_\_\_\_The portion of the male urethra that is surrounded by the prostate is called the membranous urethra. 6\) \_\_\_\_\_\_Hypertrophy of the prostate gland makes urination quite difficult for males. 7\) \_\_\_\_\_\_The bulbourethral glands are located inferior to the prostate gland and produce a clear mucous secretion that aids lubrication during sexual intercourse. 8\) \_\_\_\_\_\_Sperm swim are sluggish in an acidic environment below a pH of 6. 9\) \_\_\_\_\_\_Viable sperm cannot be produced at temperatures below body temperature. 10\) \_\_\_\_\_\_An erection results from blood filling the spongy erectile tissues of the penis. 11\) \_\_\_\_\_\_One primary spermatocyte will undergo meiosis to ultimately form four sperm. 12\) \_\_\_\_\_\_Spermatids are functional sperm. 13\) \_\_\_\_\_\_The acrosome helps a sperm penetrate the follicle cells that surround the egg. 14\) \_\_\_\_\_\_The hormone that causes secondary sex characteristics in males is progesterone. 15\) \_\_\_\_\_\_Ovaries contain many tiny saclike structures called ovarian follicles, each of which consists of an immature egg surrounded by one or more layers of follicle cells. 16\) \_\_\_\_\_\_Ovulation occurs when a vesicular (Graafian) follicle releases an egg. 17\) \_\_\_\_\_\_Oocytes are carried toward the uterus by both cilia and peristalsis. 18\) \_\_\_\_\_\_The innermost layer of the uterus is called the myometrium. 19\) \_\_\_\_\_\_When a woman is not pregnant, the endometrial lining of the uterus is sloughed off about every 28 days. 20\) \_\_\_\_\_\_In a female, the labia minora are two outer, hair-covered folds of skin that enclose the delicate, hair-free folds called the labia majora. 21\) \_\_\_\_\_\_The external genitalia of a female is also called the vulva. 22\) \_\_\_\_\_\_The diamond-shaped region of a female\'s external genitalia found between the anterior end of the labial folds, the anus posteriorly, and the ischial tuberosities is called the perineum. 23\) \_\_\_\_\_\_The cyclic changes that occur monthly in the ovary constitute the ovarian cycle. 24\) \_\_\_\_\_\_A primary oocyte undergoes meiosis and produces a secondary oocyte and a polar body. 25\) \_\_\_\_\_\_Ovulation occurs during the secretory phase of the uterine (menstrual) cycle. 26\) \_\_\_\_\_\_Estrogens cause the appearance of secondary sex characteristics in females. 27\) \_\_\_\_\_\_Progesterone is produced by the corpus luteum and is needed for maintenance if a female becomes pregnant. 28\) \_\_\_\_\_\_Ovulation usually occurs on or about day 14 of the menstrual cycle. 29\) \_\_\_\_\_\_Oocytes are viable for 48-72 hours once ovulated from the ovary. 30\) \_\_\_\_\_\_The rapid mitotic cell division that occurs after the fertilization of an egg is known as cleavage. 31\) \_\_\_\_\_\_The two functional areas of the blastocyst are the morula and the trophoblast. 32\) \_\_\_\_\_\_The endoderm gives rise to the nervous system and the epidermis of the skin. 33\) \_\_\_\_\_\_Beginning at the ninth week of development, the embryo is referred to as a fetus. 34\) \_\_\_\_\_\_The process of childbirth is known as parturition. 35\) \_\_\_\_\_\_The cervix typically dilates to about 10 cm during the dilation stage of labor. 36\) \_\_\_\_\_\_The placenta and its attached fetal membranes, delivered during the placental stage of labor, are called the afterbirth. 37\) \_\_\_\_\_\_When a year has passed without menstruation, a woman has reached menarche. **MATCHING.
