(28 cards)
Which structures, seen in a coronal section of the brain, are all white matter?
corpus callosum, cerebral peduncles & internal capsule
What are the four ‘landmarks’, visible on the lateral side of the human brain, that define the lobes?
lateral fissure, preoccipital notch, end of parieto-occipital sulcus & central sulcus.
The symptoms displayed by a patient with damage to the Supramarginal and Angular gyri would be:
unable to understand reading and writing
Which of the following lists contains ONLY forebrain structures?
a) lateral ventricles, third ventricle, cerebral aqueduct
b) cerebellum, medulla, pons
c) thalamus, cerebral hemispheres, medulla
d) corpus callosum, thalamus, hypothalamus
e) cerebral hemispheres, cerebellum, superior colliculus
d) corpus callosum, thalamus, hypothalamus
A student views a plastinated RIGHT brain hemisphere from the lateral side. Which of the following would be visible to her?
superior temporal gyrus
Which of the following landmarks does NOT serve as a boundary separating lobes of the human brain?
a) lateral fissure
b) parieto-occipital sulcus
c) pre-occipital notch
d) central sulcus
e) calcarine sulcus
e) calcarine sulcus
In the human brain, the gyrus containing the primary auditory cortex is:
superior temporal
The following pairs link function to structure. Which pair is INCORRECT?
a) primary somatosensory cortex - postcentral gyrus
b) Broca’s speech area - inferior frontal gyrus
c) primary motor cortex - precentral gyrus
d) primary visual cortex - superior frontal cortex
e) primary auditory cortex - superior temporal gyrus
d) primary visual cortex - superior frontal cortex
What separates the frontal lobe of the brain from the temporal lobe?
lateral fissure
Which of the following structures, which are involved in the production of cerebrospinal fluid or its flow through the brain, is closest to the midbrain?
a) Third ventricle
b) Lateral ventricle
c) Cerebral aqueduct
d) Central canal
e) Choroid plexus
c) Cerebral aqueduct
A student studies a plastinated specimen of a human brain sectioned on the midline. Viewing the medial surface, all of the following would be visible, except for the:
a) calcarine sulcus
b) cerebral aqueduct
c) corpus callosum
d) tail of the caudate nucleus
e) temporal lobe
e) temporal lobe
True or false - Pons contains grey and white matter
True
Information received by the primary auditory cortex is interpreted and processed by
Wernicke’s area
Exner’s area does what…?
controls hand movements for writing
Broca’s speech area does…?
controls larynx and tongue for speech
Wernicke’s speech area
is the main processing centre for spoken language
Supramarginal and angular gyri
interpret visual symbols as written words
Primary motor cortex is in
the pre-central gyrus or frontal lobe
The primary somatosensory cortex
is in the post central gyrus or parietal lobe
Primary auditory cortex is in the
temporal lobe
Primary visual cortex is
in the occipital lobe
a white matter tract carrying information between the hemispheres
corpus callosum
relays almost all sensory input to the cortex
thalamus
controls internal body functions and the autonomic nervous system
hypothalamus
