A
19
Q

Importance of three triangles

A
20
Q

The vestibular system send signals via the nervous system through an autonomic function known as

A

Vestibulo-ocular reflex

21
Q

Maintains balance and controls eye positions while the head moves

A

VOR

22
Q

When the head rotates, why does the eye rotates in the opposite direction?

A
23
Q

Vestibular system is responsible for:

A

Detecting linear and angular head movement and head position in space

Assisting gaze stabilization of the visual field

Maintaining balance and postural control

Providing spatial orientation or perception of body movement

24
Q

He described the VOR as a “synergistic” interaction between vestibular and ocular systems

A

Demer
