Question

1. Animals have specialized neurons that detect the motion of the head as it moves through space. These mechanoreceptors are organized as neuroepithelia within the left and right vestibular:

apparatus

ganglia

nuclei

2. Rotational acceleration/deceleration of the head – as described by roll, pitch, and yaw – is detected by:

fluid-filled semicircular canals

the ampullae of the semicircular canals

otolith organs

3. Linear acceleration/deceleration of the head as well as the effect of gravity are detected by:

the semicircular canals

the ampullae of the semicircular canals

otolith organs

4. Balance requires the central integration of raw and processed sensory streams. Such integration occurs within the:

sensory cortex

cerebellar cortex

brainstem

5. The processed sensory stream that enables balance passes through one pair of peduncles. Which pair?

superior

middle

inferior

6. What do cerebellar neurons evaluate?

intent

body status

head status

all of the above
