Perfectly

At which time during the female reproductive cycle do rising levels of estrogen inhibit GnRH secretion by the hypothalamus?

The middle of the luteal phase

How well did you know this?

Perfectly

Negative feedback control of GnRH Secretion during the luteal phase is exerted by

progesterone

Estrogen Stimulates

a. Glandular secretions of the uterus b. Mitosis and duct growth in the mammary gland c. Lipolysis

Luteinizing Hormone Stimulates

a. Ovulation b. Completion of the first meiotic division of the oocyte c. Formation of the corpus leutum

does not stimulate uterine contractions

b. Progesterone

At Ovulation Granulosa cells produce

a. histamine b. bradykinins c. prostaglandin F2 Alpha

not produced by the placenta

Progesterone

The placenta produces all known hormone except for

thyrotropic hormone

does not increase oxytocin secretion?

c. Having the woman in labor lie on her back to relieve the pressure of the fetal head on the uterine cervix

sartoli cells

Regulate Spermatogenesis Secrete Inhibin Produce androgen binding protein

stimulates the secretion of Both FSH and LH

Hypothalamic GnRH

go through meiosis

spermatocytes

Spermatids lose cytoplasm and form a tail durring

spermiogeneis

Not caused by the preovulatory surge of LH?

b. menstruation

caused by the preovulatory surge of LH

ovulation completion of the first meoitic division of the oocyte progesterone secretion

During the luteal phase the positive feedback action on LH secretion is blocked by

progesterone

Estrogen does not stimulate

uterine glandular secretions

The acrosome reaction causes

The digestion of the zona pellucida

Sperm can survive the longest in

Estrogen stimulated cervical mucous

inhibits uterine contractions

progesterone

Secretion is stimulated by Cholescystokinin

insulin

Osteoporosis

inadequate bone protein matrix

b. Numerious overactive osteoclasts

Hyperparathyroidism

In order for an embryonic ovary to develop one needs

a. The absence of Mullerian Inhibiting Hormone

development of the embryonic brain in the male direction is determined by

testosterone

During a Human Female reproductive cycle when pregnancy does not occur the corpus luteum survives

12 days

29. Theca Internal Cells are stimulated by

LH-only

28. Which of the following can mature in any endocrine environment?

primodial follicle

30. Estrogens Stimulate

synth of androgens by granulose cells

If extra FSH is given to a woman during the follicular phase

it will rescue follicles from atresia

human corpus luteum does not produce

a. human chorionic gonadotrophin

trophoblast cells in the embryo make

human chorionic gonadotrophin

48. An enlarged endocrine organ could be an indication of

a. excessive hormone production by the organ b. inadequate hormone production by the organ c. a tumor that secretes the trophic hormone for the organ

hypoendocrine condition of hormone “a” could be the result of

d. The absence of a precursor for hormone “A”

51. The liver contributes to endocrine balance by

a. producing preprohormones b. metabolizing hormones c. producing carrier proteins for hormones

The prostaglandins found in seminal fluid are produced in the

Epididymus

The production of hormone receptors and enzymes needed to synthesize testosterone is stimulated by

normal male levels of prolactin ```

not an action of testoterone

the initial differentiation of the embryonic gonad into a testis

development to the revelatory stage

atresia

Which of the following can cause ovarian follicular atresia?

All of these

primary oocytes complete the 1st meiotic division

at ovulation

What saves the corpus luteum from going through luteolysis in a fertile reproductive cycle?

HCG

Which of the following hormones only functions in the female and has no functions in the male?

none

hormones competes with Aldosterone for its receptors in the kidney and changes in its levels influences water retention prior to menstruation

progesterone

49. Estrogen stimulates

A. contactions of the fimbria of the oviduct of the of oxidation B. production of cervical menicus that prolongs sperm survival C. Ke of vaginal epithelium that produces the femal reproductive tract from infections and damage

The highest levels of HCG in maternal blood are observed during

first trimester
