Neuroanatomy Exam Questions And Correct Answers
What sulcus separates the frontal and parietal lobes? - ANSWER central sulcus
Which lobe is said to be hidden beneath the lateral sulcus? - ANSWER insular lobe
AKA insula
Which lobe is the motor cortex a part of? - ANSWER frontal lobe
Which major gyrus is very important in motor control, and serves as the origin of all
corticospinal and corticonuclear fibers? - ANSWER precentral gyrus
(just anterior to the central sulcus)
T/F The paracentral lobule surrounds the central sulcus on the medial surface of the
cerebrum, it contains parts of the precentral and postcentral gyri so it has both motor
AND sensory function. - ANSWER True
Which gyrus is between the cingulate sulcus and the corpus callosum and connected to
the limbic system? - ANSWER cingulate gyrus
Which major gyrus is situated between the calcarine and parieto-occipital sulcus? -
ANSWER cuneus
Where is CSF produced? - ANSWER choroid plexus in ventricles
Which ventricle is contained within the open cavity of the diencephalon? - ANSWER third
ventricle
, The amount of cortex devoted to sensory and motor function of a particular body part is
dependant on what principle? - ANSWER it's determined by the COMPLEXITY/functional
importance of that structure!
for example, more cortex is devoted to the lips and hands than the thigh, even though
the thigh is a much larger structure.
What functional area of the cerebrum develops programs for skilled motor activity and
coordinates the primary motor area in the execution of movements? - ANSWER
premotor cortex
A lesion in the right hemisphere that involves the primary sensory area would result in a
loss of sensation on which side of the body? -ANSWER: loss of sensation on LEFT side
the primary sensory area receives sensation from the contralateral side of the body.
Stereognosis requires cooperation between what brain areas? - ANSWER between the
somesthetic association cortex and the primary sensory (somatosensory) cortex. the
primary sensory cortex receives sensations of pain, touch, temp, and proprioception,
and then the association cortex integrates data to bring about recognition.
What is the role of Wernicke's area? - ANSWER comprehension of what one is hearing or
reading
"sensory speech" whereas broca's is motor speech
T/F Smell and taste are integrated together because they do not possess association
cortexes. - ANSWER True
The close proximity of the olfactory cortex to the gustatory (taste) cortex is important for
integrating the two senses.
Patient X suffered from a head injury and is unable to form new, short term memories.
He does however have very ease of memories of his childhood. Patient X would most
likely have a lesion in what part of his brain? - ANSWER hippocampus
Which functional area of the brain would allow for the appreciation of shapes, color and
