Labyrinthine sense is a sensory system situated in the inner ear which perceives the position and movement of the body. This complex sense is prompted by the vestibular system and semicircular canals. It is important in the perception of balance.
For example, your labyrinthine sense helps you manage your equilibrium when spinning. You may also notice that you tend to walk towards the left when you tilt your head towards the left and vice versa. Hence, looking straight ahead helps you walk on a straight line. Moreover, passengers (like in a bus) are advised to face the way they are going to prevent motion sickness.
