The question asks which gland secretes melatonin. Let's check what each option is actually responsible for.
- Thyrotrophs: These are cells in the anterior pituitary gland that secrete thyroid-stimulating hormone (TSH), which controls the thyroid gland. They have no role in melatonin production.
- Gonadotrophs: These are also anterior pituitary cells, but they secrete LH and FSH to regulate the reproductive organs. This is unrelated to melatonin.
- Pineal gland: This is a small gland located deep in the brain that converts the neurotransmitter serotonin into melatonin, mostly during darkness. Melatonin release from the pineal gland signals the body that it is night time and helps set the sleep-wake cycle.
- Adrenal gland: This gland secretes cortisol, aldosterone, and catecholamines such as adrenaline, none of which is melatonin.
Of the four options, only the pineal gland is responsible for making and releasing melatonin.
Therefore, the correct answer is Pineal gland.

- In respect of female reproductive cyck, which of the following statements are correct
1. The female reproductive cycle consists of menstrual phase, a pre-ovulatory phase, ovulation and a post ovulatory phase.
2. During the menstrual phase, small secondary follicles in the ovary begin to enlargewhile the uterus is shedding its lining
3. During the pre-ovulatory phase, a dominant follick continues to grow and begins tosecret estrogen and inhibin while the uterine lining begins to rebuild
4. Ovulation results in the release of an ovum and the shedding of the uterus lining tonourish and support
the release ovum
5. After ovulation, a corpus luteum forms the ruptured follicks and begins to secreteprogesterone and estrogen, which it will continue to do throughout pregnancy if the eggis fertilized
6. If pregnancy does not occur, then the corpus luteum degenerates into a scar knownas corpus albicans and uterine lining is prepared to be shed again - Antidiabetic action of gliburidestart at molecular level by which mechanism
