Diagram of Ear

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 ear is important from Class 10 and 12 perspective 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.

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 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.
