Types of Receptors and Their Stimuli Match the receptor type with the environmental change that stimulates it. Type of stimulus Light energy Changes in concentrations of chemicals Any factor that causes tissue damage Changes in heat energy Changes in pressure or movement Type of receptor Chemoreceptor Mechanoreceptor Pain receptor Photoreceptor Thermoreceptor

Specialized sensory receptors detect five categories of stimuli. Pain receptors sense dangerous stimuli. Thermoreceptors detect heat or cold. Mechanoreceptors respond to mechanical energy (such as touch). Chemoreceptors respond to chemicals. Electromagnetic receptors respond to electricity, magnetism, and light.
The list below classifies sensory receptors by the stimulus that activates them. Using your textbook or other resource, name the receptor for each stimulus type. activated by touch, pressure, vibration, and stretch. activated by changes in temperature activated by light or changes in light wavelengths activated by changes in chemical concentrations in a solution activated by tissue injury or situations that may lead to tissue injury
