Our ear consists of
1 Outer ear (pinna) which passes through auditory canal leading to the ear drum (tympanum)
2 The middle ear consists of three tiny bones malleus, incus and stapes. the three bones are collectively called ear ossicals.
3 Inner ear or membranous labyrinth has two main parts-- cochlea and spiral-shaped, and semicircular canals.
The pinna collects the sound waves and conducts them through the external auditory canal. They finally strike on the ear drum which is set into vibration.
