brain psych test

Question 1

dendrites

Answer 1

branching extensions of a neuron that listens for incoming information and conducts impulses toward the cell body

Question 2

axon terminal

Answer 2

end point of neuron where neurotransmitters are stored

Question 3

axon

Answer 3

extension of a neuron through which neural impulses are sent

Question 4

myelin sheath

Answer 4

covers the axon of some neurons and helps speed neural impulses

Question 5

synapse

Answer 5

tiny fluid filled gap between axon terminus of one neuron and dendrite of another; send messages to targeted neuron

Question 6

neurotransmitters (dopamine, seratonic, etc.)

Answer 6

chemical messengers that travel across synapse from one neutron to the next and influences if a neutron will generate action potential

Question 7

central nervous system

Answer 7

brain and spinal cord

Question 8

autonomic nervous system

Answer 8

division of peripheral nervous system that controls the glands and muscles of internal organs

Question 9

sympathetic division

Answer 9

part of the autonomic nervous system that arouses the body to deal with perceived threats

Question 10

Answer 10

part of autonomic nervous system that calms the body

Question 11

endocrine system

Answer 11

set of glands that produces hormones

Question 12

old brain/new brain

Answer 12

the brainstem

Question 13

central core

Answer 13

stands on top of the brainstem; regulates basic survival functions

Question 14

cerebral cortex

Answer 14

the outer layer of your brain’s surface, located on top of the cerebrum; carries out essential functions of your brain

Question 15

occipital lobe

Answer 15

lying at the back of the head, includes primary visual processing areas of the brain

Question 16

temporal lobe

Answer 16

lying roughly above the ears, includes auditory areas of the brain

Question 17

parietal lobe

Answer 17

lying at the top of the head and toward the rear; includes somatosensory cortex and general association areas used for processing Information

Question 18

frontal lobe

Answer 18

portion of cerebral cortex lying behind the forehead involved in planning and judgement; includes motor cortex

Question 19

limbic system

Answer 19

ring of structures at the border of brainstem and cerebral cortex (amygdala, hippocampus, hypothalamus and thalamus)

Question 20

limbic system function

Answer 20

helps regulate memory, fear, aggression, hunger and thirst

Question 21

master gland

Answer 21

pituitary gland

Question 22

neuroplasticity

Answer 22

the lifelong capacity of the brain to change and rewire itself in response to the stimulation of learning and experience
