PARTS OF THE EARS
- The outer ear is the part of the ear attached to the head. It is shaped like a cup to funnel sound into the rest of the ear. Without the outer ear's unique shape, what we hear would be much more faint.
Parts found in the middle ear include:
- The auricle, which is the visible part of the ear
- The middle ear contains one of the most vital parts of the ear: the ear drum.When sound comes into the middle ear, it causes the ear drum to vibrate. These vibrations cause three small bones, the hammer, the anvil, and the stirrup, to move.
Parts found in the middle ear include:
- The ear drum
- Three small bones, the hammer, the anvil, and the stirrup
- The ear canal (later becoming the Eustachian tube), which allows air to pass from your ear to the back of your nose
- The inner ear is the deepest portion of the ear. The movement of the three small bones from the middle ear, especially the stirrup, causes liquid in the cochlea to move around. Hairs lined along the walls of the cochlea sense the liquid's movement and send messages to your brain by way of the auditory nerve. Your brain then understands the sound!
Parts of the inner ear include:
- The vestube, which is like a small bag lined with tiny hairs
- The semicircle canals, shaped like half-circles, which are small tubes connected to the vestube that are filled with liquid and lined with hairs
- The cochlea, filled with liquid and over 15,000 hair cells
- The auditory nerve, a long nerve connecting the ear and the brain (not visible on diagram)
The ear itself is one of the most delicate parts of your body! That is why it is important to correct problems of the ears quickly.
