Reveal answer Fill a bubble to check yourself
D Correct answer

The ovary is an ovum-producing reproductive organ, often found in pairs as part of the vertebrate female reproductive system. Ovaries in females are analogous to testes in males, in that they are both gonads and endocrine glands.

Multiple choice

Which of the following does not happens during the ovulatory phase of menstruation cycle?

  1. Formation of the corpus luteum.

  2. Egg is released

  3. Fimbri captures the egg

  4. The amount and thickness of mucus increases

A Correct answer
Explanation

During the leutal phase the empty follicle develops into a new structure called the corpus luteum. The corpus luteum secretes the hormones estrogen and progesterone. Progesterone prepares the uterus for a fertilized egg to implant.

  1. Shedding of uterus linning

  2. FSH & LH are released

  3. One follicle in one ovary becomes dominant

  4. The estrogen levels rise

  1. skin as pain receptor

  2. brain to connect cerebral hemisphere

  3. ovary for secretion of progesterone

  4. heart to initiate the heart beat

C Correct answer
Explanation

Yellow mass of tissue called corpus luteum in mammals is present in ovary for secretion of progesterone. It is formed after ovulation.

Multiple choice

In females, the linings of the uterus and fallopian tubes are formed by

  1. Stratified Epithelium

  2. Glandular Epithelium

  3. Ciliated Columnar Epithelium

  4. Simple Columnar Epithelium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

These are simple columnar epithelial cells, but in addition, they posses fine hair-like outgrowths, cilia on their free surfaces. These cilia are capable of rapid, rhythmic, wavelike beatings in a certain direction. This movement of the cilia in a certain direction causes the mucus, which is secreted by the goblet cells, to move (flow or stream) in that direction. Ciliated epithelium is usually found in the air passages like the nose. It is also found in the uterus and fallopian tubes of females. The movement of the cilia propels the ovum to the uterus.
