The system for sensing the position and movement of individual body parts

A coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses.

The number of complete wavelengths that pass a point in a given time

(for example, per second)

The ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows us to judge distance.

Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the objects

the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground).

a coiled bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses.

(Think of a famous music festival, this tube will begin to react when music is being performed)

Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle or movement.

diminished sensitivity as a consequence of constant stimulation.
