Q

WHAT ARE THE DIVISONS OF THE NERVOUS SYSTEM?

A

Central Nervous System
Peripheral Nervous System
Autonomic Nervous system
Somatic Nervous System

22
Q

WHAT IS THE CENTRAL NERVOUS SYSTEM?

A

made up of the brain and spinal cord

23
Q

WHAT IS THE PERIPHERAL NERVOUS SYSTEM?

A

a network of nerves that runs throughout the head, neck, and body

24
Q

WHAT IS AUTONOMIC NERVOUS SYSTEM?

A

a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure

25
WHAT IS PARASYMPATHETIC NS?
responsible for the body's rest and digestion response when the body is relaxed, resting, or feeding
26
WHAT SYMPATHETIC NS?
responding to dangerous or stressful situations
27
WHAT IS THE SOMATIC NERVOUS SYSTEM?
made up of nerves that link the brain and spinal cord to voluntary or skeletal muscles that are under conscious control as well as to skin sensory receptor
28
WHAT ARE THE TYPES OF NEURONS?
motor neuron, sensory neuron, inter neuron
29
WHAT ARE THE PARTS OF A NEURON?
dendrites, cell body, axon, myelin sheath, axon terminals, terminal buttons, synapse.
30
WHAT IS AN ABI?
the result of damage to the brain that occurs after birth, at any time during life.
31
WHAT IS APHASIA?
A language disorder that affects a person's ability to communicate.
32
WHAT IS BROCA'S APHASIA?
a non fluent aphasia in which the output of spontaneous speech is diminished and there is a loss of normal grammatical strcuture.
33
WHAT IS A CONCUSSION?
brain injury caused by a blow to the head or violent shaking of the body or head.
34
WHAT IS A STROKE?
an interruption to the blood supply in brain or bleeding from blood vessels in the brain.
35
WHAT IS A TBI?
Brain dysfunction caused by an outside force, usually a violent blow to the head.
36
WHAT IS WERNICKE'S APHASIA?
an impaired language comprehension, despite this speech may have normal rate, rhythm and grammar.
37
WHAT IS SPATIAL NEGLECT?
a neurological disorder whereby individuals are unable to notice anything on either left or right side even though there may be no sensory loss.
38
WHAT IS CTE?
a progressive and fatal neurodegenative disease linked to repeated impacts to the head
39
WHAT IS EPILEPSY?
disorder in which nerve cell activity in the brain is disturbed, causing seizures.
40
WHAT ARE NEUROLOGICAL DISORDERS?
disorders that affect the brain as well as the nerves found throughout the human body and the spinal cord
41
WHAT IS NEURODIVERSITY?
the range of differences in individual brain function and behavioural traits
42
WHAT IS EXPERIENCE-DEPENDENT PLASTICITY?
changes that occur die to your individual experiences. like learning and instrument.
43
WHAT IS EXPERIENCE- EXPECTANT PLASTICITY?
changes that occur due to specific environmental cues that the brain expects to be exposed to at particular times.
44
WHAT IS EXPERIENCE-INDEPENDENT PLASTICITY?
changes to the brain that occur regardless of experience, pre-determined by genetics.
45
WHAT IS LONG TERM DEPRESSION?
an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer following a long patterned stimulus
46
WHAT IS LONG TERM POTENTIATION?
the long lasting strengthening of neural connection due to repeated stimulation. when a pathway is stimulated it encourages more neurotransmitters to be released to bind to the post synaptic neuron, making the signal stronger and more likely to fire again in future.
47
WHAT IS A NEURODEGENERATIVE DISEASE?
disease in which cells of the central nervous system stop working or die.
48
WHAT IS NEUROPLASTICITY?
brains ability to grow and change throughout lifespan. when individuals neurons and their connections can be modified.
49
WHAT IS REROUTING?
an undamaged neuron that has lost a connection with an active neuron may seek a new active neuron and connect with it instead.
50
WHAT IS SPROUTING?
the growth of additional branches on axons or dendrites to enable new connections.
51
WHAT IS SYNAPTIC PRUNING?
process where brain eliminates extra neurons and synapses.
52
WHAT IS SYNAPTOGENESIS?
growth of axons, synapses and dendrites
