Document Summary
Terms/concepts/names which you should know (organized by topic): Initial coding of messages from the senses. Various human senses: vision, hearing, touch, taste, smell, balance ( vestibular sense), limb. Position and movement (kinesthesis), temperature, and pain. receptors, sensory neurons, sensory areas. Receptors : specialized structures that respond to a physical stimulus by producing electrical changes that can initiate neural impulses. (specialized neurons convert energy in the environment into neural energy. ) React directly to stimulation from the environment. Sensory neurons : carry neural impulses from the receptor to the central nervous system. Sensory areas : sensory neurons and pathways lead to specific sensory areas in the cortex. The conversion of energy from a physical stimulus (e. g. , light) to neural responses (action potentials). Sensory receptors translate the object into signals for the brain. A stronger stimulus (e. g. , more intense light) => larger electrical changes in the receptors =>faster rates of action potentials in sensory neurons.
