testis ID: 1. Testis
1) head of epididymis.
2) body of epididymis.
3) tail of epididymis.
3. Vas deferens
5. Urinary Bladder
6. Seminal vesicles
7. Prostate gland
8. Bulbourethral gland FUNCTION:
male gonads; produce sperm and testosterone fluid absorption to increase concentration of sperm
sperm storage .
. takes sperm from tail of epididymis to urethra
speeds up ejaculation
stores urine neutralize residual acidity in the male urethra
supply nutrients for the sperm . activate sperm
in some species supply a gel to prevent fertilization by another male
prostate gland seminal vesicles bulbourethral
urinary bladder ureters penis retractor
muscle vas deferens testis Temperature Regulation:
cools arterial blood going into the testes and warms venous blood leaving the
testes going back into the body.
9. Pampiniform plexus
contracts when testes are cold and expands when they are warm
10. Tunica dartos
pulls testes closer or farther from the body depending upon the temperature
11. Cremaster muscle
12. What is another temperature regulating mechanism found?
tail of epididymis The Male Mammalian Reproductive System
Located in the Testis:
12. Seminiferous tubules
13. Leydig cells
14. Sertoli cells where sperm production occurs
forms blood-testis barrier 16. Name the species and type of penis for picture A-C:
Bull A B Boar
fibro-elastic fibro-elastic Horse C
seminal vesicles vascular urinary bladder
Cowper's gland No ampulla 17. What is different about the boar compared to the ram or bull?
18. What are the two different penile types? Fibro-elastic and vascular
