Semicircular canal perceives ___________ 
Select and explain. 
A. Linear acceleration, B. Angular acceleration, C. Both, D. None
B: Angular acceleration
Answer: B: Angular acceleration 
Explanation: They respond to angular acceleration and deceleration. The three canals lie at right angles to each other but the one which lies at right angles to the axis of rotation is stimulated the most. Thus horizontal canal will respond maximum to rotation on the veical axis and so on. Due to this arrangement of the three canals in three different planes, any change in position of head can be detected.
