1The extrapyramidal system is the system involved in execution of movement.
- ARichtig
- BFalsch
2The planning area for movement is a region of the cortex anterior to the primary motor cortex.
- ARichtig
- BFalsch
3In the somatosensory cortex homunculus, the neurons that initate movement in the [blank_start]leg and foot[blank_end] lie in the medial cortex and the neurons that initiate movement in the [blank_start]face and arm[blank_end] lie in the lateral cortex.
- Aleg and foot
- Barms and hands
- Cface and arm
- Dfoot and leg
4Which area is not represented with an increase in size in the somatosensory homunculus?
- ATongue
- BFingers
- CTrunk
- DNose
5A single anterior horn cell (AHC) and all the muscle fibers it innervates is called a "motor unit."
- ARichtig
- BFalsch
6Label Corticospinal tract
- ACorticospinal Fibers
- BUpper motor neurons
- CAnterior horn
- DCorticospinal Fiber
- ELateral corticospinal tract
- FMuscle Fibers
- GCervical vertebrae
- HAHC
- ICaudal medulla
- JLower motor neuron
- KUpper motor neuron
- LLateral spinal tract
- MPyramidal decussation
- NAnterior horn cells (AHC)
- OMedulla
- PPrimary motor cortex
- QPrimary motor fiber
- RPyramidal Decussation
7Neurons in the primary motor cortex initiate movement of the contralateral side of the body.
- ARichtig
- BFalsch
8A lesion of the lateral corticospinal tract at the upper cervical cord results in [blank_start]ipsilateral[blank_end] weakness of the whole left side of the body. A lesion involving the corticospinal tract in the right hemisphere of the brain results in [blank_start]left-sided[blank_end] weakness.
- Aipsilateral
- Bcontralateral
- Cright-sided
- Dleft-sided
9Upper motor neuron lesions result in:
- ABabinsky sign
- BSpasticity
- CHypotonia and hyporeflexia
- DHypertonia and hyperreflexia
- EClonus
- FFasciculations
10Which of the following is NOT a typical result of a lower motor neuron lesion?
- AFasciculations and fibrillations
- BCan affect a single muscle
- CToe goes up on touching bottom of foot
- DDecreased muscle tone
11Extrapyramidal motor system is similar to the pyramidal system in that both send projections to anterior horn cells in the spinal cord.
- ARichtig
- BFalsch
12Nuclei in the extrapyramidal motor system include:
- AMedial pre-optic area
- BSubstantia nigra
- CSubthalamic nucleus
- DBasal ganglia
- ESeptal nuclei
13What is an autosomal dominant genetic disease that causes a loss of neurons in the caudate and putamen involved in the indirect pathway?
- AHuntington's chorea
- BHemiballismus
- CParkinson's disease
- DMyasthenia gravis
14Hemiballismus is caused by:
- AA decreased excitatory drive of the cortex
- BThe subthalamic nucleus stops working resulting in less activation of the globus pallidus, less inhibition of the motor nuclei of the thalamus (VA/VL), and excessive excitatory input to the motor cortex
- CDisinhibition via decrease in GABA and increase in glutamate in the motor cortex
15Loss of dopamine from substantia nigra can result in which of the following clinical features?
- ABradykinesia
- BResting tremor
- CFlinging arm movements
- DShuffling gait
- ETranscortical motor aphasia
- FDecreased affect
