Problem:

Question 1: How do the semicircular canals determine the direction of acceleration of the head?

a. The otoliths deflect hair cell cilia preferentially in one direction
b. The ampullae deflect hair cell cilia preferentially in one direction
c. The input from the three semicircular canals, each oriented in a different plane, are compared
d.The input from the outer and the inner ampullar hair cells are compared

Question 2: Why is the eardrum larger in area than the oval window?

a. It allows for sound localization (determining where a sound is coming from) due to the difference in vibration amplitude between the two membranes
b.The eardrum responds better to lower frequencies, while the oval window responds better to higher frequencies
c.The eardrum responds better to higher frequencies, while the oval window responds better to lower frequencies
d.It allows for amplification of vibrations between the eardrum and the fluid of the inner ear
