Question

Identify the proper hormonal release-response from the list below:(Choose the best answer)

A. FSH release- stimulates oogenesis and estrogen release

B. Inhibin- directly controls progesterone secretion

C. Relaxin- inhibits oxytocin secretion

D. FSH- directs formation of corpus luteum

E. Progesterone- stimulates ovulation

F. Both A and C

G.Both D and E

2. All are true of the myometrium:(Choose the best answer)

A. It is composed of smooth muscle in three layers

B. It is the site of implantation of the zygote after fertilization

C. It is the middle layer of the uterus and contracts vigorously during labor/delivery

D. It is thickest at the superior most region of the organ called the fundus

E. It is thinnest at its inferior most region called the cervix

3.In the female, estrogens:(Choose the best answer)

A. Have little effect on the uterine wall

B. Inhibit the secretion of LH and FSH during most of the cycle

C. Increase vascularization of the skin

D. Stimulate milk ejection from the breast

E. Both B and C correct

4.During spermatogenesis, haploid cells form at the ________ stage. (Choose the best answer)

A. Primary spermatocyte

B.Secondary spermatocyte

C. Spermatid

D. Spermatozoan

E. Spermatogonium

5. If pregnancy occurs, the endometrium is maintained by the___________ during the first few months until the placenta fully forms and takes over. (Choose the best answer)

A. Anterior pituitary

B. Hypothalamus

C. Corpus Albicans

D. Corpus Luteum

E. Myometrium

Answer 1

1. Both A& C are true.

The FSH has action to stimulate the oogenesis and the level of estrogen.

2. C. It is the middle layer of the uterus and contracts vigorously during labor/delivery. The layer comes in between endometrium and the perimetrium. In delivery it's the contraction of this muscle that pushes baby out.

3. Both B and C correct. Estrogen inhibit the secretion of the LH and FSH on the days other than ovulation. It also increase vascularization and skin thickness.

4. B.Secondary spermatocyte

Meosis l occurs to primary soermatocyte and secondary soermatocyte with haploid number is formed.

5. D. Corpus Luteum

The corpus luteum produce the progesterone that takes care of the uterine thickness and allow it to be in the same thickness throughout.
