Explain human ear with the help of diagram

Answer 1

The ear canal sends the sound waves to the ear drum and send it to middle ear. The hammer,anvil and the stirrup amplify the sound waves and send it to the cochlea. The cochlea receives the vibrations and converts it into electric impulse and sends it to the auditory nerve.

Answer 2

Answer:

Human ear is a sense organ responsible for hearing and body balance. The outer ear receives the sound waves and transmits them down the ear canal to the eardrum. This causes the eardrum to vibrate and sound is produced.

The External ear or the outer ear consists of :-

=>Pinna/auricle is the outermost section of the ear.

=>The external auditory canal links the exterior ear to the inner or the middle ear.

=>The tympanic membrane, also known as the eardrum, separates the outer ear from the inner ear.

The Middle ear comprises :-

=> Ossicles are the three tiny bones connected to each other that transmit sound waves to the inner ear. => These three tiny bones are stapes, malleus, and incus.

=>Eustachian Tube is a tube that connects the middle ear to the back of the nose. It helps to maintain equal pressure in the middle ear which facilitates the proper transmission of sound waves.

The Inner ear consists of :-

=>Cochlea that comprises the nerves of hearing.

=>Semicircular canals that contain the receptors that help in maintaining balance.

=>Vestibule also contains the receptors for body balance.
