WebA receptor or receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes. Some transmembrane receptors are activated by chemicals called ligands. WebDifferent sensory receptor cells are specialized for different types of stimuli, and are categorized by the type of stimulus they detect. Sensory receptor cells include (but are not limited to!)
