  1. 2. The _____ is the structure that is responsible for static equilibrium
  2. 6. The ability to sense rotation or spinning of your head is called _____ equilibrium
  3. 8. A _____ frequency results in a low pitch
  4. 13. The tube that connects the middle ear to the throat and is responsible for the popping sensation we feel in our ears is called the...
  5. 15. The ______ membrane changes the fluid waves of the cochlea into nerve signals as it gets shaken by them
  6. 19. At the ______ of the basilar membrane the hairs are longer and the membrane is looser, making it easier to shake
  7. 20. The inner part of the ear that includes the tympanic membrane and ossicles is called the ____ ear
  8. 21. People tend to ______ their ability to hear higher pitches sooner because shorter hairs die first as they are at the base
  9. 22. The most superficial part of the ear is referred to as the ____ ear
  10. 24. The second ossicle of the ear that is attached to the malleus and recieves vibrations second is called the...
  11. 25. The _____ of the basilar membrane get shaken, pushed upward, and bend, which causes a signal to be sent to the brain
  12. 26. The _____ is the structure of the ear that looks like a snail, has hearing receptors, and changes the vibrations into actual action potentials
  13. 27. The ______ window acts as a gate, letting fluid move inside the cochlea

  1. 1. The ability to sense the position of your head in relation to gravity is called ______ equilibrium
  2. 3. The ______ membrane is a bongo-shaped membrane that vibrates when a sound wave hits it
  3. 4. The sounds we hear start out as ____ of air and later cause vibration
  4. 5. A ____ frequency results in a high pitch
  5. 7. The ______ canals are fruit-loop-like structures that have fluid in them and can sense changes in dynamic equilibrium
  6. 9. The ____ window is a hole that gets vibrations from the stapes and causes fluid to move in the cochlea
  7. 10. At the _____ of the basilar membrane the hairs are shorter and the membrane is stiff, making it harder to shake
  8. 11. The tympanic ______ refers to the space where the ossicles are located
  9. 12. The part of the outer ear that channels sound waves into the external acoustic meatus is called the...

  12. 17. The tube of the outer ear that sends sound waves from the auricle to the tympanic membrane is called...
  13. 18. The first ossicle of the ear that is attached directly to the ear drum AND receives vibrations first is called the...
  14. 23. Once the tympanic membrane and ossicles begin to vibrate, the _____ in the cochlea turns into actual waves
