Question

Thick skin, long arms and legs are due to hypersecretion of hormone from
A. Thyroid
B. Thymus
C. Anterior pituitary
D. Posterior pituitary

Answer 1

Hypersecretion occurs when there is excess of one or more hormone secreted from a gland. Endocrine glands are responsible for releasing hormones into the bloodstream. The endocrine glands include; ovaries, testes, thyroid, adrenal, pineal, pituitary, parathyroid and hypothalamus. Many disorders are linked to little or more secretions of a hormone.

Complete answer:

Option A: Thyroid: - When thyroid gland is unable to produce sufficient amounts of thyroid hormone, a condition called hypothyroidism occurs. This is very commonly seen in many people. Symptoms like fatigue, weight gain and dry skin are the early indications.

Option B: Thymus: - It is a gland located between a person’s lungs. This gland is only said to be active till puberty. After that it shrinks and fat takes the place of it. Thymus produces T cells which are very important in destroying infected or cancerous cells.

Option C: Anterior pituitary: - Thick skin, long arms and legs are due to hypersecretion of the growth hormones. These growth hormones are secreted by anterior pituitary. So this is the most appropriate answer.

Option D: Posterior pituitary: - The posterior pituitary hormones are mainly synthesized by the hypothalamus. It also secretes oxytocin which is very important when child birth is concerned. It also secretes vasopressin due to which an increase in water reabsorption in kidneys occurs.

Hence, the correct answer is option (C).

Note: Hormones are the chemical messengers of the body. As we know that hormones are very important in terms of reproduction, they also help in the regulation of biological processes like hunger and blood pressure and many others. There are times when hormones become out of balance. This can lead to severe problems such as diabetes, infertility issues, bone related problems and so on.
