GENERAL HISTOLOGY

Detailed explanation-1: -Nerve cells in the hypothalamus make chemicals that control the release of hormones secreted from the pituitary gland.

Detailed explanation-2: -Endocrine glands (EN d uh k rin) produce and release their chemical products directly into the blood stream. The blood then carries those chemicals throughout the body.

Detailed explanation-3: -Endocrine glands, situated at various sites around the body, and in specialised areas of the brain. The cells in these glands secrete specific chemicals called hormones.

Detailed explanation-4: -Hormone receptors are found either exposed on the surface of the cell or within the cell, depending on the type of hormone. In very basic terms, binding of hormone to receptor triggers a cascade of reactions within the cell that affects function.

Detailed explanation-5: -The secretory products of endocrine glands are called hormones and are secreted directly into the blood and then carried throughout the body where they influence only those cells that have receptor sites for that hormone.
