a; bulbo-urethral glands 9. empties a secretion into the intermediate part of the urethra
a. bulbo-urethral glands
b. ductus (vas) deferens
d. intermediate part of the urethra
h. prostatic urethra
j. seminal gland
k. spongy urethra
7. Describe the composition of semen, and name all structures contributing to its formation. Sperm and the secretions of theprostate, the seminal glands (also containing fructose), and the bulbo-urethral glands
8. Of what importance is the fact that seminal fluid is alkaline? It buffers the sperm against the acidic environment of the femalereproductive tract.
9. What structures compose the spermatic cord? Connective tissue sheath (extension of abdominal fascia), ductus deferens, blood vessels, nerves, and lymph vessels
Where is it located? Passes from the scrotal sac through the inguinal canal into the abdominal cavity
10. Using the following terms, trace the pathway of sperm from the testes to the urethra: rete testis, epididymis, seminiferous tubule, ductus deferens.
13. Identify the female reproductive system structures described below.
uterus 1. site of fetal development
vagina 2. copulatory canal
uterine tube 3. egg typically fertilized here
clitoris 4. becomes erect during sexual excitement
uterine tube 5. duct extending from ovaries to the uterus
hymen 6. partially closes the vaginal canal; a membrane
ovary 7. produces oocytes, estrogens, and progesterone
fimbriae 8. fingerlike ends of the uterine tube
14. Do any sperm enter the pelvic cavity of the female? Why or why not? Yes. The uterine tube opens to the pelvic cavity.
15. 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.
16. 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
17. Assume a couple has just consummated the sex act and the sperm have been deposited in the vagina. Trace the pathway of the sperm through the female reproductive tract.
18. Define ovulation. Ejection of an egg (actually an oocyte) from the ovary
Microscopic Anatomy of Selected Male and Female Reproductive Organs
19. 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 .
20. 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.
21. Name the three layers of the uterine wall from the inside out.
endometrium, myometrium, perimetrium
Which of these is sloughed during menses? Endometrium
Which contracts during childbirth? Myometrium
22. Describe the epithelium found in the uterine tube. A ciliated secretory epithelium lines the uterine tube.
23. 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 layer.
24. 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.
25. On the diagram showing the sagittal section of the human testis, correctly identify all structures provided with leader lines.
The Mammary Glands
26. Match the key term with the correct description.
a; alveoli glands that produce milk during lactation
e; lobule subdivision of mammary lobes that contains alveoli
28. Describe the procedure for self-examination of the breasts. (Men are not exempt from breast cancer, you know!)
While lying down, place one arm behind your head and with the three middle fingers of the other arm palpate the breast in a circular motion, pressing first lightly, then with increasing pressure. Check the entire breast systematically using a vertical pattern from superior lateral to inferior medial regions.
