NAME _______________________________________LAB TIME/DATE ______________________________REVIEW SHEET EXERCISE42Anatomy of theReproductive SystemGross Anatomy of the Human Male Reproductive System1.List the two principal functions of the testis. Sperm production?and testosterone production2.Why are the testes located in the scrotum rather than inside the ventral body cavity? Testes are located in the scrotum to provide a slightly cooler temperature necessary for sperm production.Why This Matters3.A screening tool for benign prostatic hyperplasia and prostate cancer includes palpation of the prostate. Explain how this is accomplished. The prostate can be palpated through the anterior wall of the rectum.4.Would you expect a male with benign prostatic hyperplasia to have difficulty with ejaculation? Why or why not? Yes, this would be expected because an enlarged prostate could constrict the ducts that run through the prostate, the ejaculatory duct, and the urethra, preventing the passage of semen and urine.5.Match the terms in column B to the descriptive statements in column A.

Sperm and the secretions of the? prostate, the seminal glands (also containing fructose), and the bulbo-urethral glands7.Of what importance is the fact that seminal fluid is alkaline? It buffers the sperm against the acidic environment of the female reproductive tract.8.What structures compose the spermatic cord? Connective tissue sheath (extension of abdominal fascia), ductus deferens, blood vessels, nerves, and lymph vesselsWhere is it located? Passes from the scrotal sac through the inguinal canal into the abdominal cavity9.Using the following terms, trace the pathway of sperm from the testes to the urethra: rete testis, epididymis, seminiferous tubule, ductus deferens. seminiferous tubule rete testis epididymis ductus deferensGross Anatomy of the Human Female Reproductive System10.Name the structures composing the external genitalia, or vulva, of the female. Mons pubis, labia majora and minora, clitoris, vaginal and urethral openings, hymen, and greater vestibular glands11.Identify the female reproductive system structures described below. uterus1.??site of fetal development vagina2.??copulatory canal uterine tube3.??egg typically fertilized here clitoris4.??becomes erect during sexual excitement uterine tube5.??duct extending from ovaries to the uterus hymen6.??partially closes the vaginal opening; a membrane ovary7.??produces oocytes, estrogens, and progesterone fimbriae8.??fingerlike ends of the uterine tube12.Do any sperm enter the pelvic cavity of the female? Why or why not? Yes. The uterine tube opens to the pelvic cavity.13.What is an ectopic pregnancy, and how can it happen? Implantation of the embryo in a site other than the uterus. It most often occurs in a uterine tube, especially if the tube is partially blocked; it may also occur in the peritoneal cavity if an egg is fertilized there.14.Put the following vestibular-perineal structures in their proper order from the anterior to the posterior aspect: vaginal orifice, anus, external urethral opening, and clitoris. Anterior limit: clitoris?? urethral opening?? vaginal orifice? anus?15.Assume that a couple has just consummated the sex act and that the sperm have been deposited in the vagina. Trace the pathway of the sperm through the female reproductive tract. vagina cervix uterus uterine tube peritoneal cavity?16.Define ovulation. Ejection of an egg (actually an oocyte) from the ovaryMicroscopic Anatomy of Selected Male and Female Reproductive Organs17.The testis is divided into a number of lobes by connective tissue. Each of these lobes contains one to four seminiferous tubules , which converge to empty sperm into another set of tubules called the rete testis.18.What is the function of the cavernous bodies seen in the penis? This tissue can become engorged with blood, thus making? the penis stiff and more effective as a penetrating device.19.Name the three layers of the uterine wall from the inside out.Endometrium, Myometrium, PerimetriumWhich of these is sloughed during menses? EndometriumWhich contracts during childbirth? Myometrium20.Describe the epithelium found in the uterine tube. A ciliated secretory epithelium lines the uterine tube21.Describe the arrangement of the layers of smooth muscle in the seminal gland. Two layers of smooth muscle surround the? seminal gland, an inner circular layer and an outer longitudinal layer22.What is the function of the stereocilia exhibited by the epithelial cells of the mucosa of the epididymis? They absorb excess fluid and provide nutrients to the maturing sperm.The Mammary Glands23.Match the key term with the correct description.Key: a; alveoli glands that produce milk during lactationa.alveoli e; lobule subdivision of mammary lobes that contains alveolib.areola d; lactiferous sinus enlarged storage chamber for milkc.lactiferous duct c; lactiferous duct duct connecting alveoli to the storage chambersd.lactiferous sinus b; areola pigmented area surrounding the nipplee.lobule f; nipple releases milk to the outsidef.nipple ................
