Cranial Nerves
What cranial nerve is responsible for hearing and equilibrium?
Vestibulocochlear
The cerebrum includes:
MCA, PCA, and ACA
What are the primary cortices by lobe
Frontal- primary somatomotor
Parietal- Primary somatosensory
Occipital- primary visual
Temporal- primary auditory cortex
What part of the ear protects the middle ear and keeps it at a constant temperature
Outer
What is elasticity?
When we restore something to it's natural shape
A lesion to this nerve will cause the eye to deviate superiorly and laterally
Trochlear
What blood supply goes to the Midbrain
PCA
What is the difference between the left and the right hemisphere
left: better at linguistic and local processing
Right: facial recognition, visa-spatial, global processing, prosopagnosia, neglect
What are the Ranges of hearing loss:
Normal -10-25
Mild 26-40
Moderate 41 to 55
Mod. Severe 56 to 70
Severe 71 to 90
Profound 91 and greater
What is a condensations versus rarefaction?
Condensation is when the density of air molecules is increased and rarefaction is when it is decreased.
A lesion to this nerve will cause the eye to deviate medially
Abducens
What area of the brain is does the vertebral artery supply blood to
Medulla
What is the dorsolateral prefrontal association
self-awareness and executive-functions
What part of the ear contains the TM, Eustachian tube, ossicular chain and is responsible for impedance matching.
Middle
What is intensity?
The amount of acoustic energy
What is a pneumonic for the cranial nerves?
Oh, Oh, Oh, To, Touch, and, Feel, Very, Good, Vans, AH!
The spinal cord
What is the ventral and medial prefrontal responsible for?
impulse control and personality
What type of fluid does the inner ear contain?
perilymph-endolymph-perilymph
What is the amount of time that is takes to complete a cycle
Period
What is a pneumonic for S versus M cranial nerves?
Some, Say, Mary, Money, But, My, Brother, Says, Big, Brains, Matter, More
CNS versus PNS
CNS-brain and spinal cord
PNS- cranial and spinal nerves
What is the temporal association cortex responsible for?
Discriminating sound
What are the types of hearing loss:
conductive: normal bone, air is poor by at least 10
Sensorineural: difference is less than 10
Mixed: a combination of both
What is the # of times a waveform repeats itself
Frequency
