PATHOLOGY

Detailed explanation-1: -The thyroid gland produces three hormones: Triiodothyronine, also known as T3. Tetraiodothyronine, also called thyroxine or T4.

Detailed explanation-2: -The thyroid gland, anterior pituitary gland, and hypothalamus comprise a self-regulatory circuit called the hypothalamic-pituitary-thyroid axis. The main hormones produced by the thyroid gland are thyroxine or tetraiodothyronine (T4) and triiodothyronine (T3).

Detailed explanation-3: -The pituitary gland (located near the base of the brain) makes, stores, and releases thyroid-stimulating hormone (TSH). When TSH is secreted by the pituitary gland, it causes the thyroid gland to release more T3 and T4.

Detailed explanation-4: -The thyroid gland, the largest endocrine gland, is responsible for the production of the hormones T3, T4, and calcitonin.
