PATHOLOGY

Detailed explanation-1: -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-2: -Nerve cells in the hypothalamus make chemicals that control the release of hormones secreted from the pituitary gland.

Detailed explanation-3: -A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.
