Process incoming sensory information

Question 19

What happens when a body area is more sensitive

Answer 19

If a body area is more sensitive a larger of the somatosensory cortex is devoted to it

Answer 22

causes language impairment

Question 22

What side of the brain is language

Answer 22

Language is in the left side of the brain

Question 23

What does aphasia in Wernickkes area cause (speech comprehension)

Answer 23

causes a lack of comprehension but not production of speech

Question 24

Aphasia

Answer 24

The loss of ability to understand speech/language

Question 25

Contralateral organization

Answer 25

Left hemisphere controls right side of the body and vice versa

Question 26

Cell body (Neurons)

Answer 26

Coordinates information processing and keeps cell live

Question 26

Dendrites (Neurons)

Answer 26

Receives information from other neurons and relays it to the cell body

Question 27

Axon (Neurons)

Answer 27

Long slender projection that conducts electrical impulses away from cell body

Question 28

Synapse (Neurons)

Answer 28

The region between the axon of one neuron and dendrite of another

Question 29

Myelin Sheath (Neurons)

Answer 29

Fatty sheath that insulates axon resulting in increased speed of and efficiency of neural communication

Question 30

How do neurons send and receive messages

Answer 30

When a neuron is at rest / resting potential

Question 31

What happens when the axon is stimulated

Answer 31

Depolarization when stimulated sodium channels open and + ions rush in

Question 32

Repolarization

Answer 32

After the sodium gates closes. Potassium moves out

Question 33

Actional potential

Answer 33

An electrical signal is conducted along the length of a neuron's axon to synapse

Question 34

Synaptic Cleft

Answer 34

When the action potential reaches the terminal buttons it causes the release of neurotransmitters into the synaptic cleft

Question 35

Excitatory

Answer 35

increase the likelihood of an action potential (by causing the membrane potential to be less negative)

Question 36

Inhibitory

Answer 36

decrease the likelihood of an action potential (by causing the membrane potential to be more negative)

Question 37

Acetylcholine

Answer 37

Involved in a number of functions including voluntary motor control

Question 38

Dopamine

Answer 38

Regulates motor behavior, motivation, pleasure and emotional arousal

Question 39

What happens if there is degeneration in Dopamine

Answer 39

Degeneration of these neurons in a particular part of brain linked to parkinson's disease

Question 40

Serotonin

Answer 40

Involved in regulating sleep and wakefulness and eating behavior

Question 41

Agonist

Answer 41

drug that increases the action of neurotransmitter

Question 42

Antagonist

Answer 42

Drugs that diminishes the function of neurotransmitter
