Module 5- The Brain

Question 0

What is the thalamus

Answer 0

The brains sensory switchboard, located on top of the brainstem it direct messages to the sensory receiving areas in the cortex

Question 1

What is the brain stem?

Answer 1

The oldest part and central core of the brain. It begins where the spinal cord swells as it enters the skull. It includes the medulla, reticular formation, thalamus and cerebellum.

Question 2

What is the cerebellum?

Answer 2

The little brain attached to the rear of the brainstem and help coordinate voluntary movement and balance if damage the person could perform basic movements but would lose fine coordination skills

Question 3

What is the Medulla?

Answer 3

Located at the base of the brainstem controls basic life support functions like heartbeat and breathing

Question 4

What is the reticular formation

Answer 4

A nerve network in the brainstem that plays an important part in control and wakefulness and arousal damage can cause a coma

Question 5

What is the frontal lobe

Answer 5

The portion of the cerebral cortex lying just behind the four head that is involved in planning and judgment it includes the motor cortex

Question 6

What might happen if you cerebellum is damaged

Answer 6

If damaged you could perform basic movements but would lose fine coordination skills

Question 7

What is the limbic system?

Answer 7

The limbic system is a ring if structures at the border of the brainstem and cerebral cortex. The limbic system helps to regulate important Functions such as memory fear aggression hunger and thirst

Question 8

What does the limbic system include?

Answer 8

The limbic system includes the hypothalamus the hippocampus and the amygdala

Question 9

What is the hypothalamus?

Answer 9

The hypothalamus is a neutral structure lying below the Salamis. It helps regulate many of the bodies maintenance activities, such as eating, drinking and body temperature and is linked to emotion

Question 10

What is the hippocampus

Answer 10

The hippocampus is a neural center located in the limbic system that wraps around the back of the Thalamus; it helps process new memories for permanent storage. Resembles a seahorse

Question 11

What is the brains wrinkled outer surface called?

Answer 11

The cerebral cortex

Question 12

What is the cerebral cortex?

Answer 12

And intricate fabric of interconnected neurons that make up the bodies ultimate control and information processing center

Question 13

What is the most dramatic feature of the cortex

Answer 13

The longitudinal fissure

Question 14

What is a longitudinal fissure

Answer 14

A crevice that divides the cerebral cortex into two halves called hemispheres

Question 15

What is the corpus callosum?

Answer 15

The carpets Kausen is a large band of neural tissue that connects the two brain hemispheres and allows them to communicate with each other

Question 16

How many lobes does the brain have and what are they called?

Answer 16

The brain has four lopes frontal parietal and temporal and occipital.

Question 17

What is the parietal lobe?

Answer 17

The portion of the cerebral cortex lying at the top of the head and toward the rear; includes the summer sensory cortex and general association areas use for processing information

Question 18

What is the occipital lobe?

Answer 18

The portion of the cerebral cortex lying at the back of the head includes the primary visual processing areas of the brain

Question 19

What is the temporal lobe

Answer 19

The portion of the cerebral cortex lying roughly above the ears; it includes the auditory areas of the brain

Question 20

What is the spinal cord

Answer 20

Tail that extends down from the brain

Question 21

What is the amygdala

Answer 21

And almond shaped neutral cluster in the limbic system that controls emotional responses, such as fear and anger

Question 22

What is the motor cortex

Answer 22

The motor cortex is a strip of tissue on the rear edge of the frontal lobe controls voluntary movement of your body parts

Question 23

What type of pattern does the motor cortex control

Answer 23

Different points on the motor cortex control different parts of your body but they do so in a curious cross wired pattern. Thus the motor cortex of your right hemisphere takes care of moving on the left side of your body, and the motor cortex in your left hemisphere controls movement on the right side of your body.

Question 24

What is the somatosensory cortex

Answer 24

A brain area that registers and processes body sensations along the front edge of the parietal loves

Question 25

What is brain plasticity

Answer 25

Through the cortex can actually reprogram it’s up to compensate for a problem. This remarkable ability is called plasticity. The brain also adapts to it’s environment, molding its function to the circumstances it experiences.

Question 26

How do our two hemispheres communicate

Answer 26

They communicate constantly via the corpus callosum

Question 27

What is the difference between the left and the right hemispheres of our brains

Answer 27

And most people, language functions are located primarily in the left hemisphere.

Question 28

What are two particularly important regions in the left hemisphere

Answer 28

Brocas area and Weirnickes area

Question 29

What is the Broca’s area?

Answer 29

It is located in the left frontal lobe and directs the muscle movement involved in expressive language or speech. Damage to the Brokas area, which often happens to victims of strokes, results and difficult difficulty with spoken language. The stroke victim before I get the cannot turn those ideas and coherent words.

Question 30

What is the Weirnickes area?

Answer 30

Is located in the left temporal lobe and is involved with receptive language or your ability to understand what someone else says. Damage the weirneckes area might lead a person able to hear words but I need to look comprehend the meaning of the sentence is created with the words.

Question 31

What does the right hemisphere do?

Answer 31

The right hemisphere houses most of your brain spatial abilities. This includes judging distance understand geometric objects or packing cars truck. The right insight to help us make connections among words.

Question 32

What is the split brain operation

Answer 32

An operation in which surgeons cut the corpus Callison to prevent seizures from spreading from one side of the brain to the other in severe cases of epilepsy.

Question 33

What is a C a T scan

Answer 33

A series of x-rays taken from different angles and combined by computer into a cop is it representation of a slice through the body

Question 34

What is an M are I

Answer 34

Magnetic resonance imaging and uses magnetic field and radio waves to produce computer-generated images that distinguish among different types of soft tissue. This allows us to see different structures within the brain.

Question 35

What do you psychologist used to study brain structure

Answer 35

Computerized axial Tom tomography or CAT scan or magnetic resonance imaging and I also known as MRI

Question 36

What do you researchers used to study brain function

Answer 36

And electroencephalogram EEG, a functional MRI, or a position in mission tomography pet scan

Question 37

What is an EEG

Answer 37

And amplified recording of the waves of electrical activity that sweep across the brain surface. These electrical waves are measured by electrodes placed on the scalp. EEGs are often the choice for diagnosing sleep disorders and seizures.

Question 38

What is a functional MRI

Answer 38

I knew technology based on magnetic resonance imaging that looks that brain function instead of structure as in the original MRI.

Question 39

What is a pet scan

Answer 39

A visual display of brain activity. Researchers inject radioactive form of glucose into a person and the pet scan the text where goes in the brain while the person performs a given task.
