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 diagram of the ear is important from Class 10 and 12 perspectives and is usually asked in the examinations. A brief description of the human ear along with a well-labelled diagram is given below for reference.
Well-Labelled Diagram of Ear
- 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 contain the receptors that help in maintaining balance.
- Vestibule also contains the receptors for body balance.

Frequently Asked Questions on Diagram of Ear
What is the function of the external ear?
The external ear receives the sound waves and transmits them down the ear canal to the eardrum.
What is the function of the middle ear?
Middle ear transmits sound waves to the inner ear with the help of three tiny bones called stapes, malleus, and incus.
What is the function of cochlea?
Cochlea is a part of the inner ear and it comprises the nerves of hearing.
What is the function of semicircular canals?
Semicircular canals are present in the inner ear and they contain the receptors that help in maintaining balance.
What is the function of the vestibule?
Vestibule is present in the inner ear and it senses the position of the body.
