  • The outer ear is composed of the pinna, or ear lobe, and the external auditory canal.
  • The middle ear is an air filled space located in the temporal bone of the skull.
  • The inner has two functions; the first is hearing and the second is balance.
  • ...4 more annotations...
  • The bony labyrinth itself has three sections. 1) The cochlea is responsible for hearing, 2) the semicircular canals have function associated with balance, and 3) the vestibule which connects the two and contains two more balance and equilibrium related structures, the saccule and utricle.
  • Information from the vestibular system of the inner ear (semicircular canals, the saccule and the utricle) is sent to the brainstem, cerebellum, and spinal cord. Potential balance abnormalities do not require conscious input from the cerebrum of the brain.
  • There are three semicircular canals in the inner ear positioned at right angles to each other like a gyroscope. They are able to sense changes in movement of the body. With such changes, endolymph waves within the canals cause hair cells located within their base to move. Position of the head is sensed by hair cells of the utricle and saccule which is stimulated when the head moves and the relationship to gravity changes.
  • There are three small bones, or ossicles, that are located adjacent to the tympanic membrane. The malleus, incus, and stapes are attached like a chain to the tympanic membrane and convert sound waves that vibrate the membrane into mechanical vibrations of the three bones

  • The inner ear has two parts. The vestibular part has to do with balance. The other, the cochlea, plays an important role in hearing.
  • Movement of the cochlear fluid affects hair cells in the cochlea's Organ of Corti area. The hair cells respond according to what sounds come in to the ear, creating signals that become nerve impulses.
