7. On the figure above, number the structures spermatozoa pass through to exit the male reproductive system from where spermatids are created (#1) to the point where they exit the body.

8. On the figure above, add a star (*) next to the name of each structure that contributes to semen.

9. Label the structures listed below on the diagram of the male genitalia below.

body of epididymis efferent ductule head of epididymis lobule of seminiferous tubules rete testes

seminiferous tubules spermatic cord spermatic/testicular arteries spermatic/testicular nerves spermatic/testicular veins

straight tubules tail of epididymis tunica albuginea tunica vaginalis vas deferens

10.Match the structure listed in the table below with its corresponding description.

Name of Structure	Description
_____ vas deferens	1. produce sperm and testosterone
_____ areola	2. small convoluted tubules and site of spermatogenesis
_____ testes	3. conduct sperm to the urethra during ejaculation
_____ mammary gland	4. produces an ovum, estrogen, and progesterone
_____ fimbriae	5. a gland in mammals that produces milk
_____ corpus cavernosum and corpus spongiosum	6. ducts that carry milk from the mammary glands to the nipple
_____ labia major	7. pigmented area around the nipple
_____ seminiferous tubules	8. the larger outer folds of the vulva surrounding the inner folds; contain adipose tissue and hair
_____ ovaries	9. erectile tissues that form the bulk of the penis
_____ lactiferous ducts	10. small fingerlike projections at the end of the fallopian tubes

Part 2: Histology of the Reproductive Systems

1. Obtain the slides listed below that are available for today’s lab.
2. Focus on each sample and identify the structures listed for each type of tissue.
3. Indicate the total magnification you make each illustration at in the space provided.
4. Illustrate each tissue you observe with the microscope at the magnification you listed.
5. Label each illustration with the structures listed for each.

Ovary

More than one illustration at more than one magnification will be required to illustrate and label all structures

Label the tissue with: serosa, medulla, cortex, tunica albuginea, follicles, primordial follicles, primary follicles, secondary follicles, antral spaces, primary oocytes, corpus luteum, atretic follicles

Testis

More than one illustration at different magnifications and possibly of different slides will be necessary to illustrate and label all structures listed.

Label the tissue with: testis, epididymis, vas deferens, tunica albuginea, tunica vaginalis, seminiferous tubules, lumen of seminiferous tubule, spermatogonia, primary spermatocyte, secondary spermatocyte, spermatid

Part 3: Reproductive Systems Laboratory Activities

Labeling Male Reproductive Anatomical Model(s)

1. Use the anatomical model(s) provided to your group.
2. As a group, identify the structures listed below.
3. Write each of the following structures on masking tape or labeling tape (with correct spelling) and stick onto the model to label each structure.

bulb of the penis bulbourethral gland corpus cavernosum corpus spongiosum cremaster muscle dartos muscle ejaculatory duct epididymis external urethral orifice glans penis

lobules membranous urethra prepuce prostate gland prostatic urethra rete testes scrotum scrotal septum

seminal vesicle seminiferous tubules shaft of the penis spermatic cord spongy urethra straight tubules testis vas deferens

4. When you are done, ask your instructor to verify the labeling is correct.

5. Take a photo of your anatomical model for future reference for studying.

Labeling Female Reproductive Anatomical Model(s)

1. Use the anatomical model(s) provided to your group.
2. As a group, identify the structures listed below.
3. Write each of the following structures on masking tape or labeling tape (with correct spelling) and stick onto the model to label each structure.

ampulla of uterine tube areola breast broad ligament cervical canal cervix clitoris clitoral hood endometrium external os external urethral orifice fimbriae

fornix infundibulum of uterine tube internal os isthmus of uterine tube labia majora labia minora lactiferous duct lactiferous sinus lobe of mammary gland lobule of mammary gland mammary glands mons pubis
