Q.

Is there an egg in every follicle?

Q.

A dopamine tract from the hypothalamus plays an important role in regulating the release of prolactin. All of the following are true regarding prolactin except

1. It is produced by the anterior pituitary gland.

2. Secretion is inhibited by dopamine.

3. It stimulates milk production.

4. It is produced in the same area as oxytocin.

Q. produces ovum, estrogen and progesterone.

Q. Estrogen is secreted by

[Review question: Pg. No: 257]

1. Corpus luteum.
2. Anterior pituitary
3. Primary follicle
4. Graafian follicle

Q.

Which of the following statements is not true?

1. The largest follicle will have more FSH receptors and hence survives low levels of FSH

2. Follicles in the ovary produce estrogen

3. Primary follicle up to the antral stage is stimulated mainly by LH alone.

4. Heightened levels of estrogen will taper FSH production

Q.

How does the female body limit the number of follicles that would prepare for eggs to be released?

1. Lower oestrogen level triggers lesser follicle production

2. Higher oestrogen level stops follicle production

3. Higher progesterone level triggers follicle development

4. Lower progesterone level produces fewer follicles
