Flashcards in neuro questions Deck (27):
1

The ventral cochlear nucleus functions to process sound based on

location

2

The efferent (olivocochlear) bundle arises from neuron cell bodies located in the

superior olivary nucleus

3

The large midbrain nucleus associated with the auditory system is the

inferior colliculus

4

The large diencephalic nucleus associated with the auditory system is the

medial geniculate nucleus

5

9. The static labyrinth helps to provide balance by monitoring the

gravity vector

6

Fibers that originate from the horizontal canal in support of the vestibulo-ocular reflex terminate in the

Vestibular nuclear complex

7

Excitatory signals from the horizontal semicircular canal via a relay and in support of the vestibulo-ocular reflex reach the

Contralateral abducens nucleus

8

The primary vestibular cortex is believed to include the

posterior insular cortex

9

The cilia that express receptors for odors represent the

Processes of specialized olfactory receptor cells

10

Head trauma can sever the olfactory

nerve fibers

11

The olfactory tract consists of

mitral cell afferent and efferent axons

12

The thalamic nucleus that relays olfactory signals is the

mediodorsal nucleus

13

Olfaction is believed to reach the level of consciousness in the

posterior orbitofrontal cortex

14

visual images are reversed in the

pupil

15

The term 'magnocellular' with respect to the eye refers to

ganglion cells in the peripheral retina

16

fibers that make up the optic tract and nerve are from the

ganglion cells

17

A lesion of the optic nerve will result in

ipsilateral unilateral blindness

18

A lesion of the optic tract will result in

contralateral homonymous hemianopsia

19

The primary visual area (Brodmann's area 17) is locate

above and below the calcarine fissure

20

The dorsal visual pathway (stream) that runs across the cortex has its origin from signals processed through retinal

parasol (magnocellular) ganglion cells

21

A lesion of the postcentral gyrus results in an initial loss of

contralateral touch and pain

22

The primary output of the parietal lobe is directed to the:

frontal lobe

23

The cortical area that registers the direction and velocity of visual targets is located in the

junction of the occipital and inferior parietal lobes

24

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)

25

Working memory (the ability to organize thoughts in space and time) takes place in the:

dorsolateral prefrontal cortex

26

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

27

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
