General Senses Definitions

Matching: ____ Adaptation ____ Sensory Receptors ____ Stimulus ____ Type A Fibers ____ Sensation ____ Perception ____ Receptor Specificity ____ Receptive Field ____ Type C Fibers ____ Receptor Potential ____ Generator Potential ____ Transduction ____ General Senses ____ Special Senses ____ Sensory Pathways A. Series of neurons that relay sensory info. from the initiating point (sensory receptor) to its destination inside the CNS B. An area of the body monitored by a receptor cell C. Decrease in sensitivity of a constant stimulus that occurs at a sensory nucleus along the pathway (Ex: filter out old stimulus and allow new stimuli) D. A change in the resting membrane potential of the receptor cell E. Sensation of touch & vibration, temperature, pain, pressure, and some chemoreception F. These receptors are ALWAYS releasing neurotransmitters G. Specialized cells that can detect stimuli H. A decrease in sensitivity to a stimulus due to a CONSTANT stimulus I. These receptors have an on and off phase J. Fibers that detect slow/dull pain, unmyelinated, small diameter (slow AP) ____ Peripheral Adaptation ____ Central Adaptation ____ Phasic Receptors ____ Tonic Receptors ____ Labeled Line K. Olfaction, gustation, vision, audition, equilibrium (balance) L. The conversion of a stimulus into a physiological response M. Pathway from receptor cell to the brain N. The unique type of stimulus to which a receptor is sensitive O. Any detectable change in the environment P. Any stimulus processed by the Central Nervous System or anything that alters the resting membrane potential of the second order neuron Q. Decrease in sensitivity of a constant stimulus that occurs at the receptor R. The conscious awareness of a sensation S. Fibers that detect fast/sharp pain, myelinated, large diameter axons T. A receptor strong enough to cause an action potential in the first order neuron ANSWER KEY: H. G. O. S. P. R. N. B. J. D. T. L. E. K. A. Q. C. I. F. M.
