neuro questions Flashcards
The ventral cochlear nucleus functions to process sound based on
location
The efferent (olivocochlear) bundle arises from neuron cell bodies located in the
superior olivary nucleus
The large midbrain nucleus associated with the auditory system is the
inferior colliculus
The large diencephalic nucleus associated with the auditory system is the
medial geniculate nucleus
- The static labyrinth helps to provide balance by monitoring the
gravity vector
Fibers that originate from the horizontal canal in support of the vestibulo-ocular reflex terminate in the
Vestibular nuclear complex
Excitatory signals from the horizontal semicircular canal via a relay and in support of the vestibulo-ocular reflex reach the
Contralateral abducens nucleus
The primary vestibular cortex is believed to include the
posterior insular cortex
The cilia that express receptors for odors represent the
Processes of specialized olfactory receptor cells
Head trauma can sever the olfactory
nerve fibers
The olfactory tract consists of
mitral cell afferent and efferent axons
The thalamic nucleus that relays olfactory signals is the
mediodorsal nucleus
Olfaction is believed to reach the level of consciousness in the
posterior orbitofrontal cortex
visual images are reversed in the
pupil
The term ‘magnocellular’ with respect to the eye refers to
ganglion cells in the peripheral retina
fibers that make up the optic tract and nerve are from the
ganglion cells
A lesion of the optic nerve will result in
ipsilateral unilateral blindness
A lesion of the optic tract will result in
contralateral homonymous hemianopsia
The primary visual area (Brodmann’s area 17) is locate
above and below the calcarine fissure
The dorsal visual pathway (stream) that runs across the cortex has its origin from signals processed through retinal
parasol (magnocellular) ganglion cells
A lesion of the postcentral gyrus results in an initial loss of
contralateral touch and pain
The primary output of the parietal lobe is directed to the:
frontal lobe
The cortical area that registers the direction and velocity of visual targets is located in the
junction of the occipital and inferior parietal lobes
Diagnosed with a stroke, the patient speaks with normal emphasis and rhythm. You can make out an occasional word but the speech makes no sense. You suspect the stroke damaged the patient’s
Left posterior superior temporal lobe (BA 22)
Working memory (the ability to organize thoughts in space and time) takes place in the:
dorsolateral prefrontal cortex
The patient suffered a stroke. He appears normal in all aspect but cannot recognize a picture shown him of Presidents Obama and Reagan. You suspect the stroke damaged his
Inferior temporal-occipital region
The 16-year old patient was a well-behaved, all-A student. Following a motorcycle accident that resulted in minor head trauma (he wasn’t wearing a helmet) his classroom work plummeted and his newly acquired loud and brash behavior has landed him repeatedly in the discipline room. You suspect the head trauma affected his
prefrontal lobes
