MICROANATOMY

Detailed explanation-1: -Hypothalamus: The hypothalamus (hi-po-THAL-uh-mus) is in the lower central part of the brain. It links the endocrine system and nervous system. Nerve cells in the hypothalamus make chemicals that control the release of hormones secreted from the pituitary gland.

Detailed explanation-2: -The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body.

Detailed explanation-3: -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-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.
