15-2 Is Sensation Different from Perception? Sensation is any stimuli the body is aware of What are we not aware of? X-rays, ultra high frequency sound waves, UV light We have no sensory receptors for those stimuli Perception is the conscious awareness & interpretation of a sensation. precisely localization & identification memories of our perceptions are stored in cortex

15-3 Sensory Modalities Different types of sensations touch, pain, temperature, vibration, hearing, vision Each type of sensory neuron can respond to only one type of stimuli Two classes of sensory modalities general senses somatic are sensations from body walls visceral are sensations from internal organs special senses smell, taste, hearing, vision, and balance

15-4 Process of Sensation Sensory receptors demonstrate selectivity respond to only one type of stimuli Events occurring within a sensation stimulation of the receptor transduction (conversion) of stimulus into a graded potential vary in amplitude and are not propagated generation of impulses when graded potential reaches threshold integration of sensory input by the CNS
Image of page 4
15-5 Sensory Receptors Selectively respond to only one kind of stimuli Have simple or complex structures General Sensory Receptors (Somatic Receptors) no structural specializations in free nerve endings that provide us with pain, tickle, itch, temperatures some structural specializations in receptors for touch, pressure & vibration Special Sensory Receptors (Special Sense Receptors) very complex structures---vision, hearing, taste, & smell

15-6 Classification of Sensory Receptors Structural classification Type of response to a stimulus Location of receptors & origin of stimuli Type of stimuli they detect
Image of page 6
15-7 Structural Classification of Receptors Free nerve endings bare dendrites pain, temperature, tickle, itch & light touch Encapsulated nerve endings dendrites enclosed in connective tissue capsule pressure, vibration & deep touch Separate sensory cells specialized cells that respond to stimuli vision, taste, hearing, balance

15-8 Structural Classification Compare free nerve ending, encapsulated nerve ending and sensory receptor cell
Image of page 8
15-9 Classification by Response to Stimuli Generator potential free nerve endings, encapsulated nerve endings & olfactory receptors produce generator potentials when large enough, it generates a nerve impulse in a first-order neuron Receptor potential vision, hearing, equilibrium and taste receptors produce receptor potentials receptor cells release neurotransmitter molecules on first- order neurons producing postsynaptic potentials

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
