Proprioception

Defined as the ability for us to know how our body is positioned without having to confirm it via any normal sense (vision, touch, etc.). Sensors called spindles in all muscles can detect if a muscle is stretched or relaxed. This information is relayed to the brain to enable us to know, without conscious thought, if we are walking, sitting, or standing. These receptors are also an essential part of our ability to retain balance. If we begin to fall off balance these receptors indicate which muscles are stretching or relaxing, allowing use to make unconscious corrective movements to maintain good balance.
