Question

Which of the following hormone plays a direct and important role in the growth and development of humans?

• A. Thymosin
• B. Somatotrophin
• C. Insulin
• D. Both A and B

Answer 1

The correct option is B Somatotrophin

• Somatotrophin is a growth hormone secreted by the anterior pituitary gland.
• It promotes growth in children and adolescents. It also helps to regulate body composition, body fluids, muscle and bone growth, sugar and fat metabolism, and possibly heart function.
• Over-secretion of Somatotrophin stimulates abnormal growth of the body leading to gigantism and low secretion of Somatotrophin results in stunted growth resulting in pituitary dwarfism.
  
• Hence Somatotrophin hormone plays a direct and important role in the growth and development of humans.
• So, the correct answer is 'Somatotrophin'.
