TERMS TO KNOW
  • Sound

    Mechanical energy that travels in the form of a wave detected by our ears.

  • Mechanoreceptors

    Sensory receptors located in the ear that aid in the process of hearing.

  • Cochlea

    A coiled fluid-filled sac located in the inner ear that plays a role in sorting sound waves.

  • Tympanic Membrane

    A membrane located in the ear that vibrates in response to incoming sound waves. Also known as the “eardrum”.

  • Organ of Corti

    A structure found in the cochlea that contains hair cells, which are mechanoreceptors for sound.

  • Hair Cells

    Mechanoreceptors in the ear for sound.

  • Tectorial Membrane

    A structure in the cochlea with which hair cells interact to produce action potentials.

  • Semicircular Canals

    Three structures of the inner ear that are involved with balance and equilibrium.

  • Vestibular Apparatus

    Composed of the three semicircular canals and two fluid-filled sacs, which monitor equilibrium.

  • Decibels

    Units used to measure the intensity of sound.

  • Otolith Organ

    A part of the vestibular apparatus that help detect changes in the position of the head in space.

  • Auditory Nerve

    A nerve that carries signals from the inner ear to the brain.

  • Round Window

    A membrane that acts as a release valve for pressure.

  • Auditory Canal

    A canal that funnels sound waves from outside the ear toward the middle ear.
