Answer 2

Ampulla, vesicular gland, prostate, bulbourethral gland

Question 3

Testis

Answer 3

Contains seminiferous tubes,site of spermatogenesis

Question 4

Seminiferous tubules

Answer 4

Deliver sperm to rete testis

Question 5

Rete testis

Answer 5

Leads to efferent ductules

Question 6

Spermatozoa are developed

Answer 6

By serotonin cells by stimulation of FSH

Question 7

Interstitial/ leygid cells

Answer 7

Between S. Tubules, secrete testosterone when stimulated by LH

Question 8

Sertoli cells in males

Answer 8

Equal granulosa cells in females and both have FSHr

Question 9

Leydig cells in males

Answer 9

Equal theca interna cells in females and both have LHr

Question 10

draw the stallion repro tract

Answer 10

Cremaster muscle, Ductus deferences, head of epididymis, tail of epididymis, pampinform plexus, parietal vaginal tunic, visceral vagina tunic, testis

Question 11

Pituitary hormone effect

Answer 11

LH and FSH stimulate spermatogenesis and testosterone secretion

Question 12

Testes hormone effect

Answer 12

Testosterone and inhibin inhibit the secretion of GnRH by the hypothalamus and LH and FHS by the pituitary

Question 13

Functions of spermatic cord

Answer 13

Suspends testis in scrotum, provides heat exchange, houses cremaster muscle

Question 14

Pampiniform plexus

Answer 14

Counter current heat exchange, cools arterial blood supply, thermoregulation

Question 15

Three thermoregulation ways

Answer 15

Tunica dartos, cremaster muscle (raise/lower), p. Plexus (blood cooling)

Question 16

Epididymis

Answer 16

Convoluted duct that connects efferent ductules to ductus deferens, house spermatozoa to mature before expelling, divided into head, body, and tail regions

Question 17

Ductus deferens

Answer 17

Muscular tube that ejaculation peristaltic contraction propels sperm for epididymis to penile urethra

Question 18

Accessory sex glands produce

Answer 18

bulk of ejaculate, provides nutrients, acts as a buffer

Question 19

Ampulla

Answer 19

Add volume to ejaculate

Question 20

Vesicular

Answer 20

Adds volume and monosaccharides

Question 21

Bulbourethral

Answer 21

Secrets fluids to clear tract and gel fraction causes seminal plasma to coagulate

Question 22

Prostate

Answer 22

Produces alkaline secretion

Question 23

Scrotum

Answer 23

Cutaneous protective sac that contains the testes, thin pliable skin that is hairless, Darto muscle wrinkles skin, layer of fibroelast tissue

Question 24

Glands penis

Answer 24

Make organ of copulation, maintains columns of erectile tissue that contains blood sinusoids and sheets of connective tissue called trabeculae (horses) , also fibroelastic penis that is composed of trabeculae but is firm even when not erect, sigmoid flèche allows for retraction

Question 25

Prepuce

Answer 25

Food of skin that surrounds free end of penis, hairless moist skin that connects sheath to penis, averts when penis is extended outside body, not sheath

Question 26

Sheath

Answer 26

Prepuce or foreskin, Structure in which glans penis is retracted into, protection

Question 27

Testicular mass

Answer 27

Sperm production ability
