Question

The hormone which regulates the basal metabolism rate (BMR) of the body:-
A. Thyroid hormone
B. Thymosin
C. Corticoids
D. Pituitary hormone

Answer 1

The basal metabolism rate is known as the number of calories required by the body, during the resting time when also the digestive system is inactive from the last 12 hours.

Complete answer: 1. The thyroid hormone is secreted by the thyroid gland.
The thyroid gland synthesizes two hormones tetraiodothyronine or thyroxine (T4) and triiodothyronine (T3). The synthesis of these hormones is regulated by the amount of iodine in the body.
They are regulated by the negative feedback mechanism. The thyroid hormone is responsible for the Basal metabolism rate of the body. The thyroid hormone is mainly responsible for the metabolism of carbohydrates protein and fats. Water and electrolyte balance is also maintained by the thyroid hormone.
2. Thymosin hormone is secreted by the thymus gland.
Thymosin has an important role in the differentiation of T- lymphocytes to provide cell-mediated immunity as well as it also has it’s a major role to improve the production of antibodies in the body to provide humoral immunity.
3. Corticoids are secreted by the adrenal gland from the outer adrenal cortex.
In our body, it mainly controls the balance of water and electrolyte balancing.
Aldosterone is the main mineralocorticoid in our body.
4. There are different hormones secreted by the pituitary which stimulates the production of different hormones in our body. Hence BMR is regulated by the thyroid hormone.

So, the correct answer is “Option A ”.

Note: Pituitary hormones are growth hormone, prolactin, thyroid-stimulating hormone, luteinizing hormone, follicle-stimulating hormone, etc. which regulates different functions of the body.
