give a brief explanation of working of human ear
Answers
Answer:
The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear or cochlea to move.
Explanation:
The parts of the ear include:
External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear. ...
Tympanic membrane (eardrum). The tympanic membrane divides the external ear from the middle ear.
Middle ear (tympanic cavity), consisting of: Ossicles. ...
Inner ear, consisting of: Cochlea.
Function of Human Ear:
The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone. It is spanned by a chain of three tiny bones—the malleus (hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles.
