ANATOMY

Detailed explanation-1: -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-2: -Cells that have receptors for a particular hormone are called target cells.

Detailed explanation-3: -Target cells are cells that are receptive to a secreted hormone. dependent on three factors; the hormone levels in the blood, the receptor levels on the target cell, and hormone–receptor affinity.

Detailed explanation-4: -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).

Detailed explanation-5: -Endocrine hormones travel throughout the body in the blood. However, each hormone affects only certain cells, called target cell s. A target cell is the type of cell on which a hormone has an effect. A target cell is affected by a particular hormone be ca use it has receptor proteins that are specific to that hormone.
