Define motor learning | set of processes that bring about change in motor performance |
What is difference between neuroanatomy and neurophysiology? | anatomy-structure; physiology-function |
What are 2 anatomical divisions of the nervous system? | CNS and PNS |
What are the 2 physiological divisions of the nervous system? | somatic and autonomic |
What part of brain responsible for higher brain function? | cerebral cortex |
Frontal lobe | reasoning, planning, speech, movement, emotions, problem-solving |
Temporal lobe | perception, recognition of auditory stimuli, memory, speech |
Parietal lobe | movement, orientation, recognition, perception of stimuli |
Occipital lobe | visual processing |
Cerebellum | regulation and coordination of movement, posture, balance |
Brain stem | basic vital life functions (heart rate, respirations, etc.) |
Name two methods of synaptic communication | electrical and chemical (most common) |
Define neuron | unit of structure of nervous system |
Part of neuron that conducts toward cell body | dendrite (receives) |
Part of neuron that conducts away from cell body | axon (sends) |
Cell bodies inside the CNS | gray matter |
Axons inside the CNS | white matter |
Cell bodies outside the CNS | ganglia |
Two primary functions of the spinal cord | connect parts of PNS to the brain; responsible for simple reflexes |
How many pairs of spinal nerves | 31 pairs |

Is Post Polio Syndrome a LMN or UMN dysfunction? | LMN |
What symptoms are associated with Post Polio Syndrome? | fatigue, increased weakness of muscles, atrophy, joint pain, deformities |
Is Guillain-Barre a LMN or UMN dysfunction? | LMN |
What symptoms are associated with Gullain-Barre? | pain/tenderness of muscles, weakness, atrophy, sensory loss |
Is Myasthenia Gravis a LMN or UMN dysfunction? | LMN |
What symptoms are associated with Myasthenia Gravis? | weakness and abnormal fatigue of skeletal muscle (especially eyes) but may involve limbs, death usually results due to respiratory complication |
Are muscular dystrophies LMN or UMN dysfunction? | LMN |
What symptoms are associated with muscular dystrophies? | vary by type, severity and prognosis look different case by case |
Is Alzheimer's Disease a LMN or UMN dysfunction? | UMN |
What symptoms are associated with Alzheimer's? | dementia, slow degenerative disease, ultimately results in death, memory loss, inability to regulate emotions, personality shifts, difficulty with speech |
Is Multiple Sclerosis a LMN or UMN dysfunction? | UMN |
What symptoms are associated with Multiple Sclerosis? | autoimmune condition, course of disease variable and unpredictable, fatigue, visual/cognitive/emotional disturbances, decreased postural control, tremor, spasticity, heat intolerance |
Is Huntington's Disease a LMN or UMN dysfunction? | UMN |
What symptoms are associated with Huntington's Disease? | affects voluntary and involuntary movement, chorea, rigidity, cognitive/behavioral/psychological changes, depression, death |

Do UMN or LMN dysfunction result in weakness? | LMN |
Collection of nerve cells inside CNS | nuclei |
Collection of nerve cells outside the CNS | ganglia |
Excitable cell that receives/ sends signals | neuron |
Chemical substance that transmits impulses between neurons | neurotransmitter |
Portion of a neuron that transmits signals | axon |
