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
Q

WHAT IS PARASYMPATHETIC NS?

A

responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding

26
Q

WHAT SYMPATHETIC NS?

A

responding to dangerous or stressful situations

27
Q

WHAT IS THE SOMATIC NERVOUS SYSTEM?

A

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
Q

WHAT ARE THE TYPES OF NEURONS?

A

motor neuron, sensory neuron, inter neuron

29
Q

WHAT ARE THE PARTS OF A NEURON?

A

dendrites, cell body, axon, myelin sheath, axon terminals, terminal buttons, synapse.

30
Q

WHAT IS AN ABI?

A

the result of damage to the brain that occurs after birth, at any time during life.

31
Q

WHAT IS APHASIA?

A

A language disorder that affects a person’s ability to communicate.

32
Q

WHAT IS BROCA’S APHASIA?

A

a non fluent aphasia in which the output of spontaneous speech is diminished and there is a loss of normal grammatical strcuture.

33
Q

WHAT IS A CONCUSSION?

A

brain injury caused by a blow to the head or violent shaking of the body or head.

34
Q

WHAT IS A STROKE?

A

an interruption to the blood supply in brain or bleeding from blood vessels in the brain.

35
Q

WHAT IS A TBI?

A

Brain dysfunction caused by an outside force, usually a violent blow to the head.

36
Q

WHAT IS WERNICKE’S APHASIA?

A

an impaired language comprehension, despite this speech may have normal rate, rhythm and grammar.

37
Q

WHAT IS SPATIAL NEGLECT?

A

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
Q

WHAT IS CTE?

A

a progressive and fatal neurodegenative disease linked to repeated impacts to the head

39
Q

WHAT IS EPILEPSY?

A

disorder in which nerve cell activity in the brain is disturbed, causing seizures.

40
Q

WHAT ARE NEUROLOGICAL DISORDERS?

A

disorders that affect the brain as well as the nerves found throughout the human body and the spinal cord

41
Q

WHAT IS NEURODIVERSITY?

A

the range of differences in individual brain function and behavioural traits

42
Q

WHAT IS EXPERIENCE-DEPENDENT PLASTICITY?

A

changes that occur die to your individual experiences. like learning and instrument.

43
Q

WHAT IS EXPERIENCE- EXPECTANT PLASTICITY?

A

changes that occur due to specific environmental cues that the brain expects to be exposed to at particular times.

44
Q

WHAT IS EXPERIENCE-INDEPENDENT PLASTICITY?

A

changes to the brain that occur regardless of experience, pre-determined by genetics.

45
Q

WHAT IS LONG TERM DEPRESSION?

A

an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer following a long patterned stimulus

46
Q

WHAT IS LONG TERM POTENTIATION?

A

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
Q

WHAT IS A NEURODEGENERATIVE DISEASE?

A

disease in which cells of the central nervous system stop working or die.

48
Q

WHAT IS NEUROPLASTICITY?

A

brains ability to grow and change throughout lifespan. when individuals neurons and their connections can be modified.

49
Q

WHAT IS REROUTING?

A

an undamaged neuron that has lost a connection with an active neuron may seek a new active neuron and connect with it instead.

50
Q

WHAT IS SPROUTING?

A

the growth of additional branches on axons or dendrites to enable new connections.

51
Q

WHAT IS SYNAPTIC PRUNING?

A

process where brain eliminates extra neurons and synapses.

52
Q

WHAT IS SYNAPTOGENESIS?

A

growth of axons, synapses and dendrites
