Stimuli from the inner ear regarding head movement and position are sent to all of the following except the:

a. vestibular nuclei.

b. oculomotor nucleus.

c. parietal lobe.

d. cerebellum.

e. trigeminal nucleus.

Hi everyone. Let's take a look at this practice problem together, which structure is not concerned with the perception and processing of sound. The answer options are a superior temporal gyrus B. Parietal lobe, C, cerebellum and D trigeminal nucleus. So many parts of the brain have many different functions and not just one structure. It is responsible for the perception and processing of sound. So which of our answer options does not help with sound processing and perception. Option A the superior temporal gyrus, this is an area located in the temporal lobe just above the external ear and this gyrus contains the primary auditory cortex. Recall that the primary auditory cortex is the main area for auditory perception and processing. So option A cannot be the correct answer. Option B, the parietal lobe recall that the parietal lobe contains the somatosensory cortex and this cortex is vital for sensory processing and integration and that does include the sense of hearing. So, option B is also incorrect. Option C the cerebellum, the very first function I think of for the cerebellum is maintaining fluid co ordinated movement. However, the cerebellum has also been shown to participate in sound processing So we can eliminate option C as well. The structure that is not associated with sound perception and processing is the trigeminal nucleus. Recall that this nucleus receives sensory information from the surface of the face. So it is not a structure that is important for brain processing of sound. So the correct answer is option D trigeminal nucleus. All right, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
