AP PSYCHOLOGY

Detailed explanation-1: -To understand thyroid disease, you have to understand that the thyroid gland, located in the neck, isn’t just an automatic, independent machine. It’s regulated by the brain. The pituitary gland, a part of the brain, makes an array of hormones, including the thyroid-stimulating hormone, TSH.

Detailed explanation-2: -There are two main parts of your thyroid: the two halves (lobes) and the middle of the thyroid that connects the two lobes (thyroid isthmus). Your thyroid is made of thyroid follicle cells (thyrocytes), which create and store thyroid hormone (mainly T3 and T4), and C-cells, which secrete the hormone calcitonin.

Detailed explanation-3: -The pituitary is an endocrine gland located at the base of your brain that controls your endocrine system, including your thyroid. The pituitary affects the thyroid by producing a hormone called thyroid stimulating hormone (TSH). TSH causes cells within your thyroid to make more T3 and T4 hormone.

Detailed explanation-4: -Many glands make up the endocrine system. The hypothalamus, pituitary gland, and pineal gland are in your brain. The thyroid and parathyroid glands are in your neck.
