Name of the corticospinal tract fibers traveling through diencephalon to reach thalamus.
What the internal capsule?
100
This part of there cerebellum is used for motor planning of the extremities.
What is lateral part?
100
Name the three cerebellar peduncles and the function of each one.
What is
1. Superior- output
2. Middle- input cortex
3. Inferior- input spinal cord
100
Purposeless movements that are rhythmic and oscillatory
What is a tremor?
100
Quick, random hyperkinetic movements stimulating fragments of normal movement this can be seen in Huntington's disease.
What is chorea?
200
The caudate and the putamen make up this structure and they focus on ________.
What is striatum and input?
200
This part of the cerebellum is used for distal limb coordination.
What is intermediate part?
200
This term means slow movement and results from damage to the basal ganglia resulting in Parkinson's disease.
What is bradykinesia?
200
1. This form of tremor occurs at rest in patients with Parkinson's disease.
2. This form of tremor occurs with movement, worsens with movement trajectory in many patients with ataxia.
What is
1. Resting tremor
2. Intention tremor
200
Slow irregular writhing or squirming movement seen is patients with cerebral palsy.
What is athetosis?
300
This part of the basal ganglia is associated with outputs.
What is globus pallidus?
300
This part of the cerebellum is used for proximal control such as balance, standing up, posture, vestibular-ocular reflex.
What is the vermis?
300
This term results in slowed thinking and there is a lesion to the basal ganglia resulting in parkinson's
What is bradyphrenia?
300
Tonic muscle spasms and exaggerated reflexes caused by a lesion to the upper motor neuron
What is spasticity?
300
General incoordination; staggering, reeling gait that is caused by a cerebellar lesion.
What is ataxia?
400
The putamen and the globus pallidus make up this area.
What is Lenticular nucleus?
400
The structure of the cerebellum has the same function as the vermis but is more primitive.
What is Flocculonodular lobe?
400
1. A lesion to the UMN may cause the limb to catch but eventually give way during passive movement.
2. A lesion to the basal ganglia may result in increased rigidity causing it to be maintained throughout passive movements.
What is
1. Clasp-knife rigidity
2. Lead pipe rigidity
400
Shortening of strike and quacking of gate normally seen in PD patients.
What is festinations?
400
Inability to gage the distance, speed and power of movement; causing overshooting or undershooting of motor goal. This is caused by a cerebellar lesion.
What is dysmetria?
500
What are the five layers of the basal ganglia?
What is caudate, putamen, globis pallidus, subthalamic nucleus, and substantia nigra?
500
This part of the cerebellum is triangle shaped and beyond the pons.
What is the fourth ventricle?
500
The terms that stands for increased muscle tone.
What is rigidity?
500
Excess tone in selected parts of the body causing distorted, static positions. Comes from a lesion within the basal ganglia.
