GENERAL HISTOLOGY

Detailed explanation-1: -Your hypothalamus releases thyrotropin-releasing hormone (TRH), which triggers your pituitary gland to release thyroid-stimulating hormone (TSH), which stimulates your thyroid to release T3 and T4.

Detailed explanation-2: -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-3: -The thyroid gland produces hormones that regulate the body’s metabolic rate, growth and development. It plays a role in controlling heart, muscle and digestive function, brain development and bone maintenance.

Detailed explanation-4: -Thyroid hormone (TH) regulates metabolic processes essential for normal growth and development as well as regulating metabolism in the adult (28, 40, 189). It is well established that thyroid hormone status correlates with body weight and energy expenditure (80, 127, 143).

Detailed explanation-5: -The thyroid keeps your metabolism under control through the action of thyroid hormone, which it makes by extracting iodine from the blood and incorporating it into thyroid hormones.
