10/8/09 Sensory systems: 1 st order sensory cells/receptor cells- cells that detect something in sensory environment motor cells -cells that do motor or gland actions, often as result of sensory input interneuron -everything that is not a primary afferent cell or an efferent cell 1 st order, 2 nd order, 3 rd order, higher order sensory cells transduction process: transforming one form of energy into another kind of energy (almost always membrane depolarization); receptor cell does this receptor cells in sensory systems are often categorized by type of location of sensory energy that they transduce -ex: extero-receptors vs. intero-receptors -extero: energy being transduced is coming from outside organism -intero: energy being transduced is coming from inside organism -further categorized by type of energy: -some extero-receptors -ex: mechano-receptors, auditory-receptors, photo-detectors, magnetic field detectors, electric receptors, hot/cold-receptors, last 4 can sometimes be categorized into 1: photon-detectors
