These automatic postural adjustments can be explained in terms of two reflexes similar to the righting reflex: the vestibulo-ocular reflex (VOR) and the vestibulocollic reflex (VCR). [10] The VOR involves movement of the eyes while the head turns to remain fixated on a stationary image, and the VCR involves control of neck muscles for ...
The vestibulo-ocular reflex (VOR) is a reflex that acts to stabilize gaze during head movement, with eye movement due to activation of the vestibular system, it is also known as the cervico-ocular reflex. The reflex acts to stabilize images on the retinas of the eye during head movement. Gaze is held steadily on a location by producing eye ...
Hanger reflex - reflex of unclear purpose that causes the head to rotate to the right when the top sides of the head are under pressure, named because it can be easily activated with a coat hanger; Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung
The righting reflex is another type of reflex. This reflex positions the head or body back into its "normal" position, in response to a change in head or body position. A common example of this reflex is the cat righting reflex, which allows them to orient themselves in order to
The vestibular-ocular reflex (VOR) is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement, thus preserving the image on the center of the visual field. For example, when the head moves to the right, the eyes move to the left, and vice versa.
The vestibulo-ocular reflex. A rotation of the head is detected, which triggers an inhibitory signal to the extraocular muscles on one side and an excitatory signal to the muscles on the other side. The result is a compensatory movement of the eyes. The oculomotor nerve (III), trochlear nerve (IV) and abducens nerve (VI) coordinate eye movement.
CHICAGO (CBS) -- Seventy years after the racist murder of Chicago teen Emmett Till in Mississippi helped inspire the civil rights movement, a new exhibit on Emmett Till at the Chicago History ...
A nonconscious reaction is seen in the human proprioceptive reflex, or righting reflex—in the event that the body tilts in any direction, the person will cock their head back to level the eyes against the horizon. [15] This is seen even in infants as soon as they gain control of their neck muscles.
