Match the pituitary hormone with its principal action: List I | List II A. Growth hormone (GH) | 1. Stimulates secretion of glucocorticoids B. Prolactin (PRL) | 2. Stimulates synthesis and secretion of thyroid hormones C. Thyroid-stimulating hormone (TSH) | 3. Regulates growth of mammary glands and milk formation D. Adrenocorticotrophic hormone (ACTH) | 4. Stimulates body growth Select the correct answer using the code given below

The correct Answer is A-4, B-3, C-2, D-1 Explanation The pituitary gland, often referred to as the master gland, secretes various hormones that regulate the functions of other endocrine glands and several physiological processes in the body. These hormones include Growth Hormone (GH), Prolactin (PRL), Thyroid-Stimulating Hormone (TSH), and Adrenocorticotrophic Hormone (ACTH), each with specific target organs and actions. Statement-wise Analysis 1. A. Growth hormone (GH): - Correct. Growth hormone (GH) primarily stimulates body growth. It promotes protein synthesis, cell proliferation, and bone growth, particularly during childhood and adolescence. - Matches with List II, item 4: "Stimulates body growth". 2. B. Prolactin (PRL): - Correct. Prolactin (PRL) regulates the growth of mammary glands and milk formation (lactation) in females after childbirth. - Matches with List II, item 3: "Regulates growth of mammary glands and milk formation". 3. C. Thyroid-stimulating hormone (TSH): - Correct. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to synthesize and secrete thyroid hormones (thyroxine and triiodothyronine). - Matches with List II, item 2: "Stimulates synthesis and secretion of thyroid hormones". 4. D. Adrenocorticotrophic hormone (ACTH): - Correct. Adrenocorticotrophic hormone (ACTH) stimulates the adrenal cortex to secrete glucocorticoids, such as cortisol. - Matches with List II, item 1: "Stimulates secretion of glucocorticoids". The correct matching is A-4, B-3, C-2, D-1. Key Takeaway Pituitary hormones regulate diverse physiological functions, including growth, lactation, thyroid activity, and adrenal cortex function, through specific target gland stimulation.

Solution

The correct Answer is A-4, B-3, C-2, D-1

Explanation

The pituitary gland, often referred to as the master gland, secretes various hormones that regulate the functions of other endocrine glands and several physiological processes in the body. These hormones include Growth Hormone (GH), Prolactin (PRL), Thyroid-Stimulating Hormone (TSH), and Adrenocorticotrophic Hormone (ACTH), each with specific target organs and actions.

Statement-wise Analysis

A. Growth hormone (GH):
- Correct. Growth hormone (GH) primarily stimulates body growth. It promotes protein synthesis, cell proliferation, and bone growth, particularly during childhood and adolescence.
- Matches with List II, item 4: "Stimulates body growth".
B. Prolactin (PRL):
- Correct. Prolactin (PRL) regulates the growth of mammary glands and milk formation (lactation) in females after childbirth.
- Matches with List II, item 3: "Regulates growth of mammary glands and milk formation".
C. Thyroid-stimulating hormone (TSH):
- Correct. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to synthesize and secrete thyroid hormones (thyroxine and triiodothyronine).
- Matches with List II, item 2: "Stimulates synthesis and secretion of thyroid hormones".
D. Adrenocorticotrophic hormone (ACTH):
- Correct. Adrenocorticotrophic hormone (ACTH) stimulates the adrenal cortex to secrete glucocorticoids, such as cortisol.
- Matches with List II, item 1: "Stimulates secretion of glucocorticoids".

The correct matching is A-4, B-3, C-2, D-1.

Key Takeaway

Pituitary hormones regulate diverse physiological functions, including growth, lactation, thyroid activity, and adrenal cortex function, through specific target gland stimulation.
