Question

Answer

Corpus luteum secretes Progesterone (pregnancy hormone) ..option D

Answer

Corpus luteum secrets progestrone and estrogen .They are critical in causing changes in the uterus making it more suitable for embroy implantation in case of fertilization and otherwise it becomes inactive after 14 days causing masturation

Answer

¥¥Corpus luteum of the ovary secretes progesterone, and relaxin.

--)Prolactin is secreted by anterior lobe of pituitary gland.

--》Aldosterone is a principal mineralocorticoid secreted by the adrenal cortex and testosterone is secreted by the Leydig's cells in the testes.

Answer

After ovulation the remaining graffian follicles changes to corpus luteum it secretes only progesterone. because it is a pregnancy hormone  so it maintains pregnancy that occurs after ovulation

Answer

So answer is option D.....

Answer

Corpus luteum secrets 'progesterone'..progesterone maintains pregnancy, and acts on mammary glands stimulates the formation of alveoli and milk secretion..

Answer

Corpus luteum is temporary endocrine gland it secret mainly progesterone (pregnancy hormone) and inhibin in small amount

Answer

Progesterone

Answer

Corpus luteum produces Progesterone hormone which is responsible for maintenance of endometrium lining... ie .. its also important for pregnancy So, opt. (D) is correct

Answer

The correct answer is option 'D' - Progesterone.

The corpus luteum is a temporary endocrine structure that is formed in the ovary after the release of an egg during ovulation. It plays a crucial role in maintaining pregnancy by secreting the hormone progesterone. Let's understand this in detail:

1. Corpus Luteum Formation:
- After ovulation, the ruptured follicle transforms into the corpus luteum.
- The corpus luteum is composed of granulosa and theca cells, which were present in the follicle.
- These cells undergo a series of biochemical and structural changes to form the corpus luteum.

2. Progesterone Secretion:
- The corpus luteum is responsible for secreting the hormone progesterone.
- Progesterone is a steroid hormone that prepares the uterus for pregnancy and helps in maintaining the pregnancy.
- It is involved in the thickening of the endometrium (uterine lining) to provide a suitable environment for the implantation of the fertilized egg.
- Progesterone also inhibits the contraction of the uterine muscles, preventing premature contractions that could lead to miscarriage.

3. Role in Pregnancy:
- If fertilization occurs, the fertilized egg implants into the thickened endometrium.
- The corpus luteum continues to secrete progesterone, which supports the early stages of pregnancy.
- Progesterone helps in the development of the placenta, which is crucial for the exchange of nutrients and waste products between the mother and the developing fetus.
- It also helps in the growth and development of the mammary glands in preparation for breastfeeding.

4. Lifespan of Corpus Luteum:
- If fertilization does not occur, the corpus luteum undergoes degeneration after about 14 days.
- This degeneration leads to a decrease in progesterone levels, causing the shedding of the uterine lining, which results in menstruation.

In conclusion, the corpus luteum secretes the hormone progesterone, which is essential for maintaining pregnancy and preparing the uterus for implantation. It plays a crucial role in supporting early pregnancy and preparing the body for breastfeeding.
