GENERAL HISTOLOGY

Detailed explanation-1: -Thyroxine hormone regulates the carbohydrate, protein and fat metabolism in our body. It is secreted by thyroid gland.

Detailed explanation-2: -Insulin is the key hormone of carbohydrate metabolism, it also influences the metabolism of fat and proteins. It lowers blood glucose by increasing glucose transport in muscle and adipose tissue and stimulates the synthesis of glycogen, fat, and protein.

Detailed explanation-3: -Thyroxine plays a crucial role in heart and digestive function, metabolism, brain development, bone health, and muscle control. It affects almost all of the body’s systems, which means proper thyroxine levels are vital for health.

Detailed explanation-4: -Insulin, GH and IGF-I play a dominant role in the day-to-day regulation of protein metabolism. In humans insulin appears to act primarily to inhibit proteolysis while GH stimulates protein synthesis.

Detailed explanation-5: -TH influences key metabolic pathways that control energy balance by regulating energy storage and expenditure (40, 127, 157). TH regulates metabolism primarily through actions in the brain, white fat, brown fat, skeletal muscle, liver, and pancreas.
