The Human Ear

The Human Ear

The Human Ear is an advanced sensory organ. The ear’s main function is to transmit and transduce sound to the brain through the three parts of the ear: the Outer ear, the Middle ear and the Inner ear. The ear also helps to maintain our sense of balance.

Each section of the ear has a specific function which helps sound to travel through the ear.

The sound waves travel from the outer ear and in through the auditory canal, causing the eardrum, or tympanic membrane, to vibrate. This, in turn, causes the three small bones in the middle ear, called the hammer, the anvil and the stirrup, ear to move. These three bones, collectively known as the ossicles, are the smallest bones in the human body and are full size at birth.

The vibrations move, via the oval window, through the fluid in the cochlea in the inner ear, stimulating thousands of tiny hair cells. This results in the transformation of the vibrations into electrical impulses finally perceived by the brain as sound.

The ear consists of many small parts, but can be divided into three major parts:

  • The Outer Ear
  • The Middle Ear
  • The Inner Ear
