seminal glands secrete

A
  1. sperm which consists of spermatozoa and seminal plasma (66%) (semen)
17
Q

Bulbo uretrals glands secrete

A
  1. alkaline mucous secretion (in the urethra)
  2. lubrification (during sexual inter course)
  3. invovled in immune defense
18
Q

Prostate

A

19
Q

what is the role of the female reproductive system?

A
  1. sperm deposit

2. Egg and embryo development

20
Q

Cow female reproductive system is composed with

A
  • uterus -uterus horns
  • body
  • cervix
  • infundibulum
21
Q

Chicken female reproductive system is composed of

A
  • cloaca
  • vagina
  • utures
  • ovary where yolk is formed
22
Q

name 4 types of uterus and in which animal they are present

A
  1. Bipartite uterus (cow)
    2.Uterus Bipartite (sheep)
    3.Modified bipartite udder
    4.uterus bicornuate
    the type of uterus influences the animals teat number.
23
Q

Follicles

A

oocyte + cells stroma

in an ovary you can have primary,primordial,and secondary follicles

24
Q

describe the sequence of events for corpus luteum formation

A
  1. inside the ovary you have ovum which develop primordial follicles around itself and turn into primary follicles which get larger and become develping follicles until the follicle reaches mature stage where it would burst liberating the ovum where it becomes an early corpus luteum then fully developed corpus luteum then corpus albicans.
25
Q

the mature follicle (de graaf) in cows secretes

A

estrogen

26
Q

the cumulus granulosa cells in the ovary of the cow secretes

A

progesterone

27
Q

Corpus luteum vs Corpus albicans

A

Corpus l’auteur is formed to release progesterone and prepare the uterus for implantation and development and is released after ovulation if no fertilisation takes place.
C.L is formed every 21 days in a cowwhereas the C.A is formed during pregnancy , it is the degenerative form of the C.L

28
Q

endometrium(mucosa)

A

thick, soft , longitudinal folds

used in Nidation and gestation

29
Q

Myometrium(muscular)

A

used in contraction and delivery, 3 unequal layers of smooth muscular fiber
