fractionation allows us to
ability to activate individual muscles independently of or muscles
Dysmetria
Over- or under-shooting a traget
Dydiadochokinesia
Inability to perform rapid alternating movements like pat-a-cake
Cerebellum
action tremor
Basal Ganglia
resting tremor
The Basal Ganglia exerts it regulatory control over movement through regulating:
inhibition
Controls lower motor neurons that innervate distally located muscles; primary tract for voluntary movement
Medial Upper neuron tracts
The cerebellum receives all types of sensory information in order to:
make movement adjustments
Key neurotransmitter deficiency in Parkinsons Disease:
dopamine
Movement disorder that is common to ALL lesions in the cerebellum
ataxia
Spasticity, also termed muscle hyperstiffness or hypertonia, is a sign of:
UMN lesion
Clonus is characterized by what?
Involuntary, repetitive, and rhythmic muscle contractions in response to muscle stretch
Area of cerebellum functionally related to balance control/equilibrium:
Vestibulocerebellum
There are four pathways that carry information between the cerebellum and other structures. What is the name of the high fidelity tract that carries information between the upper extremities, neck and upper trunk proprioceptors about a movement?
Cuneocerebellar
Parkinsons Plus is a _____ disorder whereas Huntingtons Chorea is a ______ disorder.
hypokinetic;hyperkinetic
Dysarthria is seen in ______________cerebellar lesions:
cerebro
Signs and symptoms of Parkinson’s Disease or Parkinsonism
akinetic/rigid, tremors, “mask-like face”
The cerebellum controls and refines our movements by determining timing, intensity, coordination, balance and ___________________. (HINT: Did you create a mnemonic for this?)
accuracy
Example of a pathological reflex:
Babinski
The Basal Ganglia is made of five nuclei: putamen, globius pallidus, substantia nigra, subthalamic nucleus and ____________:
Caudate
