Definition

Control of the neck is exerted primarily by two sensory systems, the vestibular system in response to the signals received by the vestibular end organs (the otoliths and the semicircular canals within the vestibular labyrinths) and the proprioceptors of the cervical spine. Two automatic and stereotypical responses can be elicited by direct stimulation of these receptors. The vestibulocollic reflex (VCR) is a compensatory response of the neck muscles when head motion is sensed by the vestibular organs in the inner ear. The cervicocollic reflex (CCR) is a compensatory response of the neck muscles that is driven by neck proprioceptive inputs during motion of the body.

Description of the Theory

The function of the VCR is to stabilize the position of the head in space and thereby stabilize gaze in space [1]. The function of the CCR is to stabilize the head on the body and, thereby, provide information about motion of the head with respect to the trunk [2]. These reflexes are...
