23
Q

hormone secreted by the hypothalamus that acts on the AP to release gonadotrophins

A

Gonadotrophin-releasing hormone (GnRH)

24
Q

male sex hormone that stimulates the accessory sex glands, male sex drive and development of male secondary sex (masculine) characteristics.

A

Testosterone

25
Q

hormone produced by the CL and also at the placenta mainly responsible for progestational proliferation in the uterus for implantation and pregnancy maintenance; mammary and uterine gland development

portion of the brain that regulates reproduction, hunger, body temperature and other functions

A

Hypothalamus

32
Q

Where can we find the hypothalamus?

A

in the floor of the 3rd ventricle

33
Q

produced mainly in the ovary and placenta responsible for female to come physiologically into heat and be receptive to the male; cyclic change of female tubular genital tract; secondary female sex
characteristics.

A

Estrogen

34
Q

Name three hormone (Estrogen)

male sex drive

A

Libido

40
Q

part of the pituitary gland located at the base of the brain that produces several hormones

A

Anterior pituitary (AP) or adenohypophysis

41
Q

the degeneration or destruction of an ovarian CL

A

Luteolysis

42
Q

Give one reason of degeneration or destruction of an ovarian CL

A

Prostaglandin

43
Q

one of the two testes of a male or ovaries of a female; organ which produces sex cells

A

Gonad

44
Q

gonadotrophic hormone produced and released by the AP that stimulates the production of estrogens, development of ovarian follicles (together with LH) in female, and spermatogenesis in male

A

Follicle-stimulating hormone (FSH)

45
Q

the time from breeding or conception of a female until she gives birth to her young (pregnancy/gravid)

A

Gestation

46
Q

the deposition of semen in the female reproductive tract

A

Insemination

Q

the act of sexual intercourse, where semen of the male is deposited in the reproductive tract of female during mating or breeding or service

A

Copulation

48
Q

the rupture of a ripe/matured follicles as a response to LH surge, shedding or releasing the ovum

A

Ovulation

49
Q

gonadotrophic hormone produced and released by the AP which in female, synergistically with FSH, stimulates estrogen secretion, follicle maturation, initiates ovulation, and formation and rentention of CL; in male, stimulation of interstitial cells to produce testosterone

A

Leutinizing hormone (LH) or instertitial cell-stimulating hormone (ICSH)

50
Q

cells between the semiferous tubules of the testicle that produce testosterone

A

Interstitial cells or Leydig cells
