ANATOMY

Detailed explanation-1: -Thyroid hormone (TH) regulates metabolic processes essential for normal growth and development as well as regulating metabolism in the adult (28, 40, 189).

Detailed explanation-2: -Growth hormone (GH), a master regulator of somatic growth, also regulates carbohydrate and lipid metabolism via complex interactions with insulin and insulin-like growth factor-1 (IGF-1).

Detailed explanation-3: -Metabolism: thyroid hormone increases the basal metabolic rate. It increases the gene expression of Na+/K+ ATPase in different tissues leading to increased oxygen consumption, respiration rate, and body temperature.

Detailed explanation-4: -Final Answer: The rate of growth and metabolism is controlled in the body by thyroid hormone.

Detailed explanation-5: -Thyroxin is an iodine-containing hormone which is secreted by the thyroid gland. It regulates the metabolic rate of the body. Increase in the secretion of thyroxin results in increase in metabolism. It also influences the general growth of the body, mental development, body temperature, etc.
