MICROANATOMY

Detailed explanation-1: -In endocrinology, target cells can refer to the cells where hormones have an effect. Target cells are capable of responding to hormones because they display receptors to which the circulating hormone can bind. Modulation of these factors can control target cell response.

Detailed explanation-2: -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.

Detailed explanation-3: -The “target” cells for a particular hormone have receptors, either on the cell membrane, or the case of lipid soluble hormones that can pass through the membrane, inside the cell. Only the cells that have the special receptors for that hormone will respond to exposure.

Detailed explanation-4: -Definitions of target cell. any cell that has a specific receptor for an antigen or antibody or hormone or drug, or is the focus of contact by a virus or phagocyte or nerve fiber etc. type of: somatic cell, vegetative cell.

Detailed explanation-5: -All classes of hormones elicit the majority of their physiological effects via specific receptors which are located in three separate compartments of target cells: cell membranes (peptide and glycopeptide hormones), cytoplasm (steroid hormones) and nucleus (thyroid and steroid hormones).
