16
Q

what covers the septa

A

smooth muscles to help move immature sperms

17
Q

what are the 2 major parts inside the testes

A

seminiferous tubules
interstitium

18
Q

what are the seminiferous tubules the site of

A

sperm production

19
Q

what are the seminiferous tubules

A

ducts collect sperm to rete testis in the center –> tubes that bring the sperm to the epididymis

20
Q

what is the interstitium composed of

A

connective tissue
nerve
blood vessels
leydig cells

21
Q

what do leydig cells produce

22
Q

what are the boar testis structure similar to

23
Q

difference between bull and boar testies

A

the boar has more pronounced interstitium

24
Q

why is the boar intersitium more pronounced than the bulls

A

Leydig cells produce a wider array of androgens, C16, C19 steroids plus estrogens

25
what is a consequence of the boar testes location
it is against the abdominal cavity of which reduced the efficiency of heat exchange
26
why do boars have a large volume
large seminal vesicles
27
what do the bulbo-urethral glands in boars produce
gel
28
why do bulbs-urethral glands in boars produce gel
they are large
29
characteristics of boar ejaculation
copious ejaculate and prolonged ejaculation
30
do boars have smaller or larger sperm reserves compared to bulls
smaller
