Balance & The Vestibular System



Proprioception - ability to know where our body parts are in relation to one another. Uses sensors on muscles, joints, skin, and tendons to figure out position. Can be disrupted temporarily by rapid growth or weight loss.

Kinesthesia - ability to know where our body is in relation to the world around us. Relies on vestibular system as well as sensors on muscles, joints, skins, and tendons.

Dizziness and nausea can be caused by inner ear infections.
