PATHOLOGY

Detailed explanation-1: -The thyroid gland secretes two main hormones, thyroxine and triiodothyronine, into the bloodstream. These thyroid hormones stimulate all the cells in the body and control biological processes such as growth, reproduction, development, and metabolism.

Detailed explanation-2: -Pituitary. The pituitary gland is located below the brain. Usually no larger than a pea, the gland controls many functions of the other endocrine glands.

Detailed explanation-3: -Long-term changes include growth and development. Produces hormones, such as thyroxine, that control energy-related reactions and other functions in cells. Release adrenaline, which triggers a response to emergencies or excitement.

Detailed explanation-4: -The endocrine system is regulated by a feedback loop involving the hypothalamus, pituitary gland and peripheral target tissues. Growth hormone, IGF-1 and several other hormones travel through the circulation to the growth plate to regulate linear growth.

Detailed explanation-5: -The hypothalamus is the master switchboard. It’s the part of the brain that controls the endocrine system. That pea-sized structure hanging below it is the pituitary gland. It’s called the master gland because it regulates the activity of the glands.
