Document Summary
Senses: systems though out our bodies allow us transform energy and information into neural impulses. Perceptions: the process of organization and interpretation of genetically transmitted knowledge and knowledge gathered from experience. Transduction: the conversion of stimuli detected by receptor cells to electoral impulses that are transported to the brain: vision, audition, smell (olfaction, taste (gustation, touch, balance. Transduction: process of turning energy detected around us into nerve impulse. Photoreaction: reaction of a chemical in a nerve cell due to light. Molecular reactions: taste buds on our tongues. Respond to molecules in the substances we put in our mouths: smell is based on specialized detectors that detect kinds of molecules in the air. 1. auditory which occurs through the transduction of movement of hair cells in the ear: touch occurs through the transduction of pressure and heat. Thalamus: all the senses (except smell) send the action potential to this area. Smell goes to olfactory nerve and the limbic system.
