Answer 5

Transport sperm from testes to penis

Question 6

Accessory Sex Glands

Answer 7

Fibroelastic (Most farm animals) or vascular type (stallion)

contains vas defers, pan-uniform plexus, and external cremaster muscle nerves (raise muscle)

Answer 11

Connective tissue which holds testis together (white covering on ovary or teste)

Question 12

Answer 12

Sperm producing cells (true germinal epithelium)

Question 13

Rete Testis

Answer 13

Function in sperm transport from seminiferous tubules (100)

Question 14

Caput Epididymis (Head)

Answer 14

Function in maturation of spermatozoa fluid absorption

Question 15

Corpus Epididymis (Body)

Answer 15

Maturation of spermatozoa

Question 16

Answer 16

Final maturation and storage, only sperm capable of fertilization

Question 17

What animal does NOT have sigmoid Flexure

Answer 17

Horses

Question 18

Fibroelastic

Answer 18

• boar, bull, ram
• fibrous, hard sheath of connective tissue all the way through penis
• penis does not expand in diameter (rigid and extends)

Question 19

Vascular

Answer 19

• Stallion & humans
• penis increases in diameter and length when aroused
• “bells out” to plug cervix of female during ejaculation

Question 20

Scent

Answer 20

Flehmen Response (exposure of nasoplatine duct to absorb pheromones)

Question 21

Cryptordisms

Answer 21

• lack of tests resent into scrotum and thus thermoregulation is absent (Horses)

Question 22

Bilateral

Answer 22

• sterile
• no spermatogenesis
• testosterone is produced

Question 23

Unilateral

Answer 23

• fertile
  *reduced sperm producing capacity

Question 24

Testis descent occurs late

Answer 24

(common in boars and stallions)

Question 25

What factors effect thermo regulation of Testis?

Answer 25

1. Location
2. Insulation
3. Sweat Glands
