Question 5 of 19

1

Select from the dropdown lists to complete the text.

Therefore, damage to Wernicke's area will cause ( receptive, expressive ) dysphasia/aphasia whereas damage to Broca's area will cause ( expressive, receptive ) dysphasia/aphasia

Explanation

Question 6 of 19

1

Strangely, Wernicke's & Broca's areas tend to only exist unilaterally (on one side of the brain). In most people, they tend to both be found on the right side of the brain.

Select one of the following:

True
False

Explanation

Question 7 of 19

1

Select from the dropdown lists to complete the text.

In terms of the visual pathway, after the optic nerves cross at the optic ( chiasm, nucleus, radiation ) they become optic tracts. These optic tracts move up into the Thalamus where they synapse with optic radiations at the ( lateral geniculate, medial geniculate, lentiform, solitary ) nuclei, which then radiate towards and into the primary visual cortex.

Explanation

Question 13 of 19

1

Select from the dropdown list to complete the text.

The ( inferior, superior ) colliculus is the principal midbrain nucleus of the auditory pathway.

Explanation

Question 14 of 19

1

The superior colliculus plays a large role in which of the following?

Select one of the following:

It helps to provide motor innervation to the neck muscles, facilitating rotation of the neck
As a part of the visual pathway it co-ordinates the movement of the eyes
Forms the fine touch part of the dorsal column/medial lemniscus pathway

Explanation
