Hyposecretion of ......................... in children causes dwarfism A Thyroxine hormone B Growth hormone C Adrenaline hormone D Vasopressin hormone

To address the question regarding what hormone's hyposecretion causes dwarfism in children, let's analyze the options:

1. Thyroxine hormone: This hormone is important for metabolism but primarily affects growth indirectly through its role in metabolism. Its deficiency can lead to growth issues, but it is not the direct cause of dwarfism.

2. Growth hormone (GH): This hormone is produced by the pituitary gland and is crucial for growth and development in children. Hyposecretion of growth hormone can directly lead to dwarfism, causing a significant reduction in growth and stature.

3. Adrenaline hormone: Primarily involved in the body’s 'fight or flight' response, it does not play a direct role in growth. Adrenaline deficiency is not associated with dwarfism.

4. Vasopressin hormone (Antidiuretic hormone, ADH): This hormone regulates water retention in the body. Its deficiency leads to conditions like diabetes insipidus, but it does not have a direct relation to height or growth.

Final Answer

The correct answer is B. Growth hormone. Hyposecretion of growth hormone in children can lead to dwarfism, characterized by significantly reduced growth and stature.
