ANATOMY

Detailed explanation-1: -Hyperprolactinemia can be caused by hypothyroidism. Thyrotropin-releasing hormone (TRH) from the hypothalamus stimulates prolactin and TSH release.

Detailed explanation-2: -Hyperthyroidism occurs when there is excessive thyroid hormone synthesis or release.

Detailed explanation-3: -It communicates with your posterior lobe by tissue called the pituitary stalk. Your hypothalamus sends signals in the form of releasing hormones to tell the anterior and posterior pituitary when to release (secrete) its hormones.

Detailed explanation-4: -The pituitary gland and hypothalamus both control the thyroid. When thyroid hormone levels drop too low, the hypothalamus secretes TSH Releasing Hormone (TRH), which alerts the pituitary to produce thyroid stimulating hormone (TSH). The thyroid responds to this chain of events by producing more hormones.
