PATHOLOGY

Detailed explanation-1: -Cell membrane – The cell membrane contains receptors for protein hormones and adrenal medullary hormones (catecholamines) Cytoplasm – Steroid hormone receptors are found in the cytoplasm of target cells.

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: -Receptors for peptide hormones tend to be found on the plasma membrane of cells, whereas receptors for lipid-soluble hormones are usually found within the cytoplasm.
