1

Autonomic nervous system

Division of the PNS that controls glands & muscles of internal organs

2

Peripheral nervous system

Sensory & motor neurons connect the CNS to the rest of the body

3

Parasympathetic nervous system

Division of the autonomic nervous system that calms the body

4

Occipital lobes

Back of the head

5

Corpus callosum

Neural fibers connecting the two brain hemispheres & carrying messages between them

6

MRI

Use of magnetic fields & radio waves to produce computer generated images

7

Wernicke's Area

Language reception; left temporal lobe

8

PET

A visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task

9

cerebellum

Processes sensory input & coordinating movement output & balance

10

neuron

A nerve cell

11

amygdala

Component of the limbic system linked to emotion

12

endorphins

Opiate like neurotransmitters linked to pain control and pleasure

13

Frontal lobes

The portion of the cerebral cortex lying just behind the forehead

14

electroencephalogram

Amplified recording of the waves of electrical activity that sweep across the brain�s surface

15

Motor cortex

Rear of frontal lobes

16

Neural networks

Interconnected neural cells

17

Parietal lobes

Top of the head towards the rear

18

myelin

Layer of fatty tissue segment ally encasing the fibers of many neurons

19

Sensory neurons

Neurons that carry incoming information from the sense receptors to the CNS

20

Somatic nervous system

The division of the PNS that controls the body�s skeletal muscles

21

brainstem

Responsible for automatic survival functions

22

synapse

Junction between axon tip of the sending neuron and the dendrite of the receiving neuron

23

Glial cells

Cells in the nervous system that support, nourish and protect neurons

24

Biological psychology

A branch of psychology concerned with the links between biology & behavior

25

Split brain

Two hemispheres of the brain are isolated by cutting the connecting fibers

26

Adrenal glands

Glands that release epinephrine & norepinephrine

27

Action potential

Brief electrical charge that travels down the axon

28

Association areas

Areas not involved in primary motor or sensory functions

29

lesion

Tissue destruction

30

hypothalamus

Directs several maintenance activities, governs endocrine system via pituitary gland & is linking to emotion
