Sensory Systems
Introduction
The sensory systems include vision, hearing, smell, taste, touch, balance, and internal body awareness. Sensory organs and nerves help the brain understand the body and environment.
This information is educational and is not intended to diagnose medical conditions. Symptoms can have many causes, and persistent or concerning symptoms should be evaluated by a qualified healthcare professional.
Primary Functions
Supporting balance, safety, communication, and daily activities
This function works together with other organs and body systems to support everyday health.
Helping regulate responses to internal and external conditions
This function works together with other organs and body systems to support everyday health.
Signs of Healthy Function
- Vision, hearing, balance, smell, taste, and touch that are stable for the individual
- Ability to navigate usual environments safely
- Sensory changes addressed with appropriate supports
Healthy function looks different across ages, disabilities, chronic conditions, and individual baselines. Changes from your usual function can matter more than comparison with someone else.
