General SensesHuman sense that have simple neural pathways. They are touch, temperature, pain, chemical and pressure detection, and body positions. Have simple neural pathways. Special SensesHuman sense that have complex pathways. Receptors for these senses are housed in specialized organs. Include: gustation, olfaction, vision, audition, and equilibrium. Have complex neural pathways. GustationTaste OlfactionSmell AuditionHearing Receptive FieldA specific region that is monitored by a sensory neuron Labeled lineNeural link between receptor and cortical neurons of the central nervous system Sensory codingThe pattern of action potentials. Provides the CNS with such information as intensity, duration, variation, and movement of the stimulus Referred painPart of the body where pain is felt is different from the part of the body at which the painful stimulus is applied. When the body projects a sensation, usually pain, to another part of the body. Tonic and phasic receptorsWhat are the 2 types of sensory receptors? Tonic receptorSensory receptors that are always active. Example: pain receptors Phasic receptorsSensory receptors that are usually inactive and are "turned on" with stimulation. These receptors provide information on the rate of change of a stimulus. Examples: touch receptors; wearing clothes; braces ThermoreceptorsSensors for changes in temperature. Have wise distribution in the body, being found in the dermis, skeletal muscles, and hypothalamus.
