  • What does equilibrium allow us to do?

    Maintains our balance and be aware of our orientation in the space around us.

  • What ear structure separates the external and middle ear.

    The tympanic membrane (ear drum)

  • What structures are in the inner ear?

    - cochlea

    - vestibule

    - semicircular canals

  • What is the external ear made of?

    Elastic cartilage

  • What does the external ear do?

    Collects sound waves and channels them into the typanic membrane.

  • What is the function of the tympanic membrane?

    Vibrates as sound waves hit it which allows the middle ear ossicles to transfer the waves to the middle ear.

  • What is the function of the auditory tube?

    Equalize air pressure.

  • What are the differences between adult and infant auditory tubes?

    Adults - long and angled; opens only during swallowing and yawning

    Infants - short and straight; always open

  • What are the 2 divisions of the inner ear?

    - Bony labyrinth

    - Membranous labyrinth

  • What do the semicircular canals have?

    Receptors for dynamic equilibrium.

  • What receptors does the cochlea have?

    Hearing

  • What receptors does the membranous labyrinth have?

    Hearing and equilibrium

  • What receptors does the vestibule have?

    Static equilibrium

  • What structures of the semicircular canals contain receptors for dynamic equilibrium?

    Ampulla > crista ampullaris

  • Describe the pathway of equilibrium.

    Equilibrium receptors > vestibular branch of CN VIII > cerebellum (for balance) > up the brainstem > cerebral cortex
