IPA Neuro Exam Flashcards
Nerves vs ganglia
Nerves are bundles of peripheral axons
Ganglia are clusters of peripheral neuronal cell bodies
What do motor endings of neurons do
Innervate effectors (muscle fibers and glands)
What is Praxis
ability to perform a motor activity
What is apraxia
inability to perform a voluntary movement in the absence of deficits (motor strength, sensation, coordination)
What is dyspraxia
Decreased ability to perform an activity
What is constructional apraxia
unable to construct or draw a simple shape or design
What is paresis
impaired strength or weakness
What is hemiparesis
weakness of one half of the body
What is plegia
absent strength
Contrast hemiplegia, paraplegia, and quadraplegia
Hemiplegia- paralysis of 1/2 of body
Paraplegia- Paralysis of lower extremities
Quadriplegia- paralysis of all extremities
What does a continuous headache suggest
muscle spasm
What does a recurrent headache suggest
migrane or cluster headache
What does a throbbing headache suggest
vascular concerns
How do we classify a petit mal seizure
Absent seizures, loss of consciousness around 10 seconds
How do we classify a grand mal seizure
Tonic-clonic seizure with convlusions
How do we classify a myoclonic seizure
contractions of face and upper extremities, no loss of consciousness
What is ataxia
persistant unsteadiness while standing
What are the two changes of consciousness
Confusion- disturbed processing of information
Delirium- percieves information abnormally
What are the 2 types of dysphasia
Expressive (nonfluent or Broca’s aphasia)- Labored speech pattern, poor articulation, unaltered comprehension (Able to think, cant speak)
Receptive (fluent or Wernicke’s aphasia)- Speak fine but do not make any sense at all when speaking (cognition is impaired). Also have difficulty understanding what other people are saying
Most common cause of dementia
Alzheimer’s disease
Causes of CVA/Stroke by percentage
Thromboembolic (80% clot. Usually from DVT that goes to brain)
Hemorrhagic (20%- Hypertension is top cause)
Transient ischemic attacks (TIAs)- short episodes of neurological dysfunctions- Small bleeds or small clots that cause temporary deficits
