Question 1

The ovarian cycle consists of which two main phases?

Accepted Answer

Follicular and luteal

Answer

The ovarian cycle is divided into the follicular phase (dominant follicle matures) and the luteal phase (corpus luteum forms after ovulation).

Question 2

Which hormone surge directly triggers ovulation?

Accepted Answer

Luteinizing hormone (LH)

Answer

A midcycle LH surge from the anterior pituitary triggers final follicular maturation and rupture, releasing the oocyte.

Question 3

The fallopian tube is divided into which four anatomical segments from proximal to distal?

Accepted Answer

Interstitial, isthmus, ampulla, infundibulum

Answer

From uterus outward, the four segments are interstitial (within the uterine wall), isthmus (narrow), ampulla (wide, site of fertilization), and infundibulum (funnel-shaped opening with fimbriae).

Question 4

The corpus luteum forms from which structure following ovulation?

Accepted Answer

Graafian (mature) follicle

Answer

After the Graafian follicle releases its oocyte, the remaining granulosa and theca cells luteinize to form the corpus luteum, which secretes progesterone.

Question 5

Which ligament directly connects the ovary to the lateral wall of the uterus?

Accepted Answer

Ovarian (utero-ovarian) ligament

Answer

The ovarian ligament (utero-ovarian ligament) runs within the broad ligament to attach the medial pole of the ovary to the uterine cornua.
