Definition

An exteroceptor is a sensory receptor that detects stimuli from the external environment, such as light, sound, touch, temperature, and chemicals. Think of them as the body's external sensors 📡, gathering information about the world around you. Unlike interoceptors, which monitor the internal environment, exteroceptors focus on the outside world. They enable us to interact with and respond to our surroundings. These play a huge role in movement.

Etymology

The word 'exteroceptor' combines 'extero-' (from Latin 'exterus', meaning 'outer' or 'external') and 'receptor' (from Latin 'recipere', meaning 'to receive'). The combined term indicates a receptor that receives external information. It emphasizes its role in sensing the outside world. It is relatively recent.
