Chapter 2.6 The Cerebral Cortex

Question 1

The cortex can be “mapped” in three ways: ______, _____ , ____

Answer 1

gross anatomy, microscopic anatomy,
neurological function

Question 2

The cerebrum is consists of: ____ , ____ , ____

Answer 2

Sulci, Gyri, Fissure

Question 3

______ They are the hill/clefts

Answer 3

Sulci (singular: sulcus)

Question 4

______ They are the ridges/valleys formed along the sulci

Answer 4

Gyri (singular: gyrus)

Question 5

______ The large sulcus

Answer 5

Fissure

Question 6

What are the six distinct layers of cerebral cortex?

Answer 6

Layer I (molecular), Layers II and IV (external & internal granular), Layers III and V (external & internal pyramidal), Layer VI (multiform layer)

Question 7

_______ it is a layer that consists of small neurons with no cell bodies at all. Instead, it is made up
of the nerve fibers of cells forming connections with other layers.

Answer 7

Layer I (molecular)

Question 8

______ it is a layer that contain large numbers of small cells known as
granule cells.

Answer 8

Layer II and IV (external & internal granular)

Question 9

________ it is a layer that characterized by large numbers of the
triangular-shaped pyramidal cells.

Answer 9

Layer III and V (external & internal pyramidal)

Question 10

______ It is a layer that has many types of neurons, which merge into the white matter that lies below the cortical layers.

Answer 10

Layer VI (multiform layer)

Question 11

The cerebral cortex can be divided into four lobes: _____ , ____ , ____ , ______

Answer 11

occipital, parietal, temporal, and frontal lobes

Question 12

______ it is a lobe that its main target is for visual information. Damage to any part of primary visual
cortex (posterior part) causes cortical blindness in the related part of the visual field. And a
tumor in the occipital lobe ordinarily evokes only simple sensations, such as flashes of light

Answer 12

Occipital lobe

Question 13

______ it is a lobe that monitors all the information about eye, head, and body positions and passes
it on to brain areas that control movement, spatial information and numerical information.

Answer 13

Parietal lobe

Question 14

______ it is a lobe that e primary cortical target for auditory information. A tumor in the temporal
lobe may give rise to elaborate auditory or visual hallucinations.

Answer 14

Temporal lobe

Question 15

______ it is a lobe that is the “control panel” of our personality and our ability to communicate.

Answer 15

Frontal lobe

Question 16

What are different functions located in each lobe divided based on functional areas namely: _____ , _____ , _______

Answer 16

sensory cortex, motor cortex, and association cortex.

Question 17

_______ It is a functional areas that is found in the occipital, temporal, and parietal lobes. It processes incoming
information from the sensory systems.

Answer 17

Sensory cortex

Question 18

The occipital lobe contains the _____

Answer 18

primary visual cortex

Question 19

The primary auditory cortex is located in the ________

Answer 19

temporal lobe

Question 20

The postcentral gyrus of the parietal lobe contains the _______ , which is the highest level of processing for information about touch, pain, position, and skin temperature.

Answer 20

primary somatosensory
cortex

Question 21

The precentral gyrus is the ________ that provide the highest
level of command for voluntary movements. The primary motor cortex is located in the ___________

Answer 21

motor area of the cortex : located in the precentral gyrus of the frontal lobe

Question 22

The __________ are areas located primarily in the frontal,
temporal, and inferior parietal lobes. Association are the areas for connecting and integrating
sensory and motor functions. For example, combining visual and auditory information which
allows us to see the world as an integrated whole rather than discrete bits.

Answer 22

association cortex
