Motor System Disorders Flashcards
What does corticospinal tract do
EPS
Cerebellum
What is a major thing that would happen for each of there was a lesion (bonus)
—-
Upper motor neurone lesion
Where do these lesions lie
What are the signs of this
How do the limbs and sides differ
Pto
Tone and tendon reflexes?
Which extensors and flexors are stronger
Which system is responsible for:
Fast fluid movement
Smooth and learned movement
Purposeful movement
Posture ad valance control
What are they helped by
—
Increased limb tone, exaggerated reflexes, one sided, not able to do skilled movement. What is this
—
Extra-pyramidal lesion - what is it responsible for
What do you see here
—
Cerebellum lesion
What do you see here, what is it responsible for
What are the signs
Ataxia, posture and gait, tremor and ataxia, nystagmus, dysarthria, head tremor
Pt is unsteady on feet, has task directed tremor, has jerks and nystagmus horizontally. What rid this
—
What are some causes of cerebellar lesions. List a few examples of each of these
Tumours, vascular, infection, developmental, toxic, inherited, MS, hydroceph, hypothyroid
Cerebellum lesions
For differing causes, how would they present in terms of disease severity and time. Pto for promt
Vascular, infection, inflam, neoplasia, degenerative
What does a lower motor neurone lesion look like
Bonus — what are some examples of such lesions
Weakness, wasting, hypotonia, reflex loss, fasiculations, contracture
What is posture and balance mediated by and from where.
—-
What is voluntary movement mediated by and from where
—execution / planning
—-
How do reflex movements happen — mediated by what
—-
Myasthenia gravis — symptom and presentation
