Document Summary
Sound - the interpretation of vibrations in the air. Packet of compressed air followed by a packet of less compressed air. Hit ear and cause vibrations --> hearing (leads to action potentials) Sticking out part - auricle - gathers sound waves from environment and direct them towards ear canal. Tube that runs towards middle and inner ear. Once it reaches the bone, it"s a hole or opening in your temporal bone. Temporal bone has tunnels - where all these structures are found. Contains hair, ear wax - protective (protect from debris, water, dust) Border between external and middle ear is the tympanic membrane (thin) (ear drum) drum) When the sound waves come in, they hit this ear drum and vibrate it. The external ear directs soundwaves towards ear drum. Oval window - brings soundwaves in the inner ear. Round window - the soundwaves come out of inner ear.
