Document Summary
General senses have receptors throughout the whole body: somatic: located in skin, muscle, joints. Touch, pressure, proprioception, temperature, pain: visceral: located in internal organs. Special senses: receptors located within specific organs: smell, taste, sight, hearing, balance, take light, chem signals, sound waves, etc and make it into an action potential. Mechanoreceptors: compression, bending, stretching of cells; physically changing something about the ion channels to open the gates: touch, pressure, proprioception, hearing, balance. Chemoreceptors: binding a chemical or molecule to have a response to cause ions to move through the membrane and cause depolarization; chemicals become attached to receptors on their membranes; smell and taste. Nociceptors: extreme mechanical, chemical, or thermal stimuli; pain receptors.
