Check reflex

Definition

The check reflex is a neurological mechanism that helps regulate muscle tension and ensures smooth coordination of movements by providing immediate feedback to the muscles during activity. It plays a crucial role in maintaining posture and balance by adjusting muscle activity in response to changes in body position.

Related terms

Muscle Spindle: A sensory receptor located within a muscle that detects changes in muscle length and contributes to the check reflex by initiating a response to stretch.

Gamma Motor Neurons: Specialized neurons that regulate the sensitivity of muscle spindles, playing a key role in modulating the check reflex and muscle tone.

Proprioception:

The sense of self-movement and body position, often referred to as the "sixth sense," which is closely tied to the function of the check reflex by providing necessary feedback about body position and movement
