Study Notes
Types of Receptors
- Thermoreceptors detect changes in temperature.
- Mechanoreceptors detect mechanical compression or stretching.
- Nociceptors detect painful or damaging stimuli.
Specialized Receptors
- Photoreceptors detect light.
- Chemoreceptors detect changes in taste, smell, O2 level, CO2 level, and osmolality of body fluids.
Sensory Principles
- The principle of specificity states that each type of receptor is highly sensitive to one type of stimulus and almost nonresponsive to other types.
- The labeled line principle states that nerve fibers are specific to transmitting only one modality of sensation.
- The four primary modalities of sensation are pain, touch, sound, and sight, and are described as the principle types of sensation that humans can experience.
