GENERAL HISTOLOGY

Detailed explanation-1: -The thyroid–a butterfly-shaped gland in the front of your neck–makes hormones that control the way your body uses energy. Your thyroid controls your metabolism, which is how your body turns food into energy, and also affects your heart, muscles, bones, and cholesterol.

Detailed explanation-2: -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-3: -Your thyroid’s main job is to control the speed of your metabolism (metabolic rate), which is the process of how your body transforms the food you consume into energy. All of the cells in your body need energy to function. When your thyroid isn’t working properly, it can impact your entire body.

Detailed explanation-4: -The thyroid gland is a vital hormone gland: It plays a major role in the metabolism, growth and development of the human body. It helps to regulate many body functions by constantly releasing a steady amount of thyroid hormones into the bloodstream.
