Usage: plural form; used in biology and neuroscience; contrasts with interoceptors (internal stimuli) and proprioceptors (body position)

Examples

• The exteroceptors in your skin allow you to feel temperature and pressure from the outside world.
• Eyes and ears contain exteroceptors that respond to light and sound waves.
• Exteroceptors enable us to detect and react to environmental changes around us.
• The sensory neurons connected to exteroceptors send signals to the brain about external stimuli.
• Touch receptors in the fingertips are examples of exteroceptors that provide detailed sensory information.
