Q

Pons

A

responsible for alerting the brain of incoming information.

23
Q

Cerebellum

A

in the back of the brain, responsible for coordination and balance

24
Q

Brain plasticity

A

when one area is damaged than the brain compensates for that.

25
Q

4 main scanning techniques

A

EEG, Pet Scan, MRI, and CT

26
Q

EEG

A

connect sensors to the brain, this test gives you brain waves. It is used for sleep studies

27
Q

Pet Scan

A

inject a dye in blood stream that lights up parts of the brain

28
Q

MRI

A

gives you the best image of the brain. It’s just a big magnet

29
Q

CT

A

“X-Ray” of the brain

30
Q

2 main parts of the nervous system

A

Central & Peripheral

31
Q

Central

A

brain & spinal cord

32
Q

Peripheral

A

everything that connects to your spinal cord

33
Q

Symatic

A

controlled by motor cortex

34
Q

Autonomic

A

controlled by the medulla

35
Q

Autonomic is split again

A

Sympathetic & Parasympathetic

36
Q

Sympathetic

A

Fight or flight

37
Q

Parasympathetic

A

calming of your body

38
Q

Main vessel of the Central & Peripheral nervous system is the _______

A

neuron

39
Q

Neuron

A

Send messages

40
Q

DENDRITES

A

branch like extensions, extend from the cell body. receive messages for the neuron

41
Q

CELL BODY/SOMA-

A

the brain of the neuron

42
Q

AXON-

A

tail looking structure takes the message away from the cell body, Releases message to another neuron through the end bulbs at the end of the axon

43
Q

Myelin Sheath

A

covers the axon helps to speed process up

44
Q

Synaptic Gap

A

space between neurons

45
Q

receptocites

A

They open the gate to the new neuron

46
Q

Reuptake.

A

Once the message is sent the neurotransmitters return to the sending neuron.

47
Q

6 main neurotransmitters

A

Acetocoline (ACH), Dopamine, Glutamate, Gabba, Norepinephrine, and Serotonin

48
Q

Acetocoline (ACH)

A

helps in muscle movement. In our peripheral nervous system. Overdose can be toxic to the body and can lead to Parkinson’s disease.

49
Q

Dopamine

A

helps the body feel well. mood elevator.

50
Q

Dopamine hypothesis-

A

shortage of dopamine can lead to schizophrenia.

51
Q

Glutamate

A

major excitatory neurotransmitter in the brain. Help neurons interact with each other

52
Q

Gabba

A

a major inhibitory transmitter in the body

53
Q

Norepinephrine

A

similar to adrenaline, speeds the body up

54
Q

Serotonin

A

mood elevators SSRI’s are antidepressants which boost serotonin levels in the body
