Human Sexuality Exam #2
1. Urethra: urine and semen transport
2. Erection: - better penetrate the vagina
- deposit sperm near the cervix
3. 3 cylinders of erectile tissue: Corpora cavernosa (2)
Corpus spongiosum (contains the urethra)
4. Glans Penis: conelike end of penis
5. Foreskin: fold of skin that can cover part or all of glans
6. Circumcision: surgical removal of the foreskin
7. Root of the penis: -extends into the body below the pubic bone
-attached to internal pelvic muscles, can be felt in the perineum
8. Scrotum: loose, wrinkled pouch beneath the penis and contains the testicles
1/6
,9. Function of the scrotum: keep the testicles 3 degrees cooler than body temp
10. Cremaster muscle: moves the scrotum closer to or farther from the body
11. Testicles: two egg shaped glands in the scrotum
12. Function of the testicles: - testosterone production
- spermatogenesis
13. Testosterone production: - most important male hormone
- made by leading cells in the testicles
14. Seminiferous tubules: produce and store sperm
15. Sertoli cells: secrete nutrition for sperm development.
16. Steps of spermatogenesis: spermatogonium, primary spermatocyte, secondary spermatocyte, sper-
matids
17. Spermatids reorganize:: - nucleus forms the compact head
- covered by an acrosome
2/6
, 18. Midpiece: energy source
19. Flagellum: propels the mature sperm
20. Ejaculation: psychological process; seminal fluid is powerfully expelled from the penis
21. Vas deferens: 18 inch tube; carries sperm from the testicles
22. Seminal vesicles: secretes nutritional bath for traveling sperm
23. Prostate gland: secretes fluid that neutralizes vagina acidity
24. Cowpers gland: contribute fluid that cleans the urethra of lethal acidic urine
25. Breasts: mostly muscle and no functional purpose
