Brain - Cerebrum

The Brain - 4 Major Parts - Cerebrum

QuestionAnswer
The WHAT is the largest part of the brain? Cerebrum
The cerebrum is divided into WHAT and WHAT hemispheres? Right and left
The cerebral hemispheres are joined together by bands of white matter that form a large fiber tract called the WHAT? Corpus Callosum (the corpus callosum allows the right and left sides of the brain to communicate with each other)
The cerebrum contains a thin layer of gray matter called the WHAT? Cerebral cortex
The WHAT forms the outermost portion of the cerebrum? Cerebral cortex
The gray matter of the WHAT allows us to perform higher mental tasks such as learning, reasoning, language and memory. Cerebral cortex
The bulk of the cerebrum is composed of WHAT matter located directly below the cortex? White
The bumpy surface of the cerebrum has numerous markings. The surface of the cerebrum is folded into elevations that resemble speed bumps - the elevations are called WHAT? Convolutions or gyri (singular gyrus)
The extensive folding arrangement on the surface of the cerebrum called WHAT increases the amount of cerebral cortex or thinking tissue. Convolutions or gyri
Convolutions or gyri are separated by grooves called WHAT? Sulci (singular sulcus).
A deep sulcus is called a WHAT? Fissure
Sulci and fissures separate the cerebrum into WHAT? Lobes
The WHAT sulcus and the WHAT sulcus separate the lobes. Central and lateral
The longitudinal WHAT separates the left and right cerebral hemispheres. Fissure
This lobe is responsible for voluntary motor activity, personality, behavioural expression, high performance tasks such as learning, thinking (aka executive functions). Frontal lobe
This lobe also contains the primary motor area (cortex). Nerve impulses that originate in the primary motor cortex control voluntary muscle movement. Frontal lobe
When you decide to move your leg, the nerve impulse originates in the WHAT gyrus, or WHAT motor cortex of the frontal lobe. The axons of these motor neurons form the voluntary motor tracts that descend down the spinal cord. Precentral gyrus or primary motor cortex
The WHAT represents the amount of brain tissue that corresponds to a function of a particular body part? Homunculus
Movements of the hand are much more delicate and complicated than the movements of the foot. Therefore, the amount of brain tissue devoted to hand and finger movement is much WHAT than the amount devoted to foot and toe movement. Greater
In addition to its role in voluntary motor activity the WHAT plays a key role in motor speech? Frontal lobe
The part of the frontal lobe concerned with motor speech is call WHAT? Broca's area (in most people is in the left hemisphere)
Just above Broca's area is an area called the frontal WHAT? It controls voluntary movements of the eyes and lids. Eye field
Because the parietal lobe receives sensations from the body it is called the WHAT? Primary somatosensory area (temp, pain, touch, sense of where your body is)
The parietal lobe is also concerned with reading, speech and WHAT? Taste
Both the parietal and temporal lobes interpret the sensation of WHAT? Taste
The temporal lobe receives sensory info from the ears and allows you to hear. What is this area called? Primary auditory cortex
The temporal lobe also receives sensory info from the nose and allows you to smell. This area is called WHAT? Olfactory area
This lobe contains the visual cortex. What is this lobe called? Occipital lobe
The speech area spans 3 what three lobes? Temporal, parietal, occipital lobes
For most people, the speech area is located in the WHAT hemisphere? Left
Large areas of the cerebral cortex are called association areas. These areas are concerned with analyzing, interpreting and integrating information. Name 3 association areas. auditory assoc. area, visual assoc. area, somatosensory assoc. area

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
