When both ovary of rat are removed then which hormone is decreased in blood
When both ovary of rat are removed then which hormone is decreased in blood
- Oxytocin
- Prolactin
- Estrogen
- Gonadotrophic releasing factor
The Correct Option is C
Solution and Explanation
The correct option is (C) : Estrogen
A neuropeptide secreted by the posterior pituitary is called oxytocin. Milk production mostly utilises prolactin. The anterior pituitary produces GnRH, which promotes the release of LH and FSH. The blood plasma level of oestrogen will be impacted if both ovaries are removed because theca interna cells of Graafian follicles generate oestrogen. The hormone known as oestrogen is primarily responsible for controlling how female accessory reproductive organs, secondary sexual characteristics, and sexual behaviour grow and develop.

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Human Endocrine System
The human endocrine system is a messenger system that balances or controls distant target organs through feedback loops of hormones released by the internal glands of an organism right into the circulatory system. The hypothalamus is the neural control node for all endocrine systems, in invertebrates.
Functions of the Human Endocrine System are:
The endocrine system controls a variety of body functions through hormone release. Hormones are built by the endocrine system's glands and pass throughout the bloodstream to various organs and tissues in the body. Hormones then command these organs and tissues about how to act.
The Endocrine System is in charge of the following bodily functions:
- Metabolic rate
- Development and growth of a human being
- Reproduction and sexual function
- Heart Rate
- Blood pressure
- The appetite is the need to eat
- Controls cycles of sleep and wakefulness
- Controls the temperature of the body
