Human Ear

Your ear helps you hear.

  • Ears are located in the middle of either side of a human’s head.
  • Ears are the only hearing organs in the human body, functioning mainly to receive sound, but also help maintain balance.
  • The visible portion of an ear is part of the outer ear, and is called an ‘ear flap’, ‘auricle’ or ‘pinna’.
  • The ear flap or pinna provides protection for the internal parts of the ear, and it also collects and helps to transport sound to the inner ear.
  • Ears consist of three main sections – the inner ear, middle ear, and outer ear.

  • Human’s hear due to sounds being channeled through the ear to the eardrum, which vibrates three small bones that cause vibrations into a fluid in the cochlea, where 20,000 nerve cells send messages to the brain.
  • Earaches and sometimes other pains in the ears, are caused when the tube that removes mucus and helps control pressure, the Eustachian tube, is blocked by cold.
  • Rough treatment of the visible ear can cause deformation, or a ‘cauliflower’ appearance, due to blood cutting off nutrients, killing parts of the organ.
  • Glands in the ear create earwax or cerumen, which is a yellow substance that helps clean and protect the organ.
  • Piercing the earlobe, visible at the bottom of the ear flap, is and has been a common practise in the past millenniums, although too much pressure on the earlobe can cause it to tear.
