Document Summary
Sensory receptor organs act as lters of the environment. Stimulus capable of triggering a sensory response (ex) infrared isn"t a stimulus because we can"t pick it up. Receptor cells detect and convert environmental stimuli into electrical signals. Labeled lines different sensory modalities send action potentials along separate nerve tracts (info from skin to brain is different from info from eye to brain). * we talked about having a certain reality and how we react to this particular representation, and this isn"t as accurate because we don"t hear everything. Somatosensory receptors: sensitivity to different somatosensory stimuli is a function of the kinds of receptors, areas with larger numbers of receptors are more sensitive to stimulation than areas with relatively fewer receptors, humans have two kinds of skin: Glabrous skin: skin that does not have hair follicles but contains larger numbers of sensory receptors than do other skin areas.
