Health & Kinesiology
The nerve fiber that transmits information from the neuron is the: A) Dendrite B) Axon C) Synapse D) Myelin
Motor neurons are also called: A) Interneurons B) Afferent neurons C) Efferent neurons D) Impulse neurons
This type of neuron is most frequently found in the nervous system. A) Interneurons. B) Afferent neurons. C) Efferent neurons. D) Impulse neurons.
The forebrain consists of the A) Cerebrum and diencephalon. B) Cerebellum and brainstem. C) Cerebrum and cerebellum. D) Diencephalon and brainstem.
The __________ cortex is the location of the transition between the perception of sensory information and the resulting action. A) Sensory B) motor C) Sensorimotor D) Association
This area of the cerebral cortex is primarily responsible for organizing movements before they are initiated. A) Primary motor cortex B) Premotor area C) Supplementary motor area D) Parietal lobe
Parkinson's disease is the result of a dysfunction of this area of the brain. A) Cerebral cortex B) Cerebellum C) Basal ganglia D) Diencephalons
The copy of neural signals about an intended movement sent by the motor cortex to the cerebellum is known as the: A) motor output copy. B) sensorimotor copy. C) cortico-cerebellar copy. D) efference copy.
This part of the brain is not a part of the brainstem that is significantly involved in motor control. A) Substantia nigra B) Pons C) Medulla D) Reticular formation
The pyramidal and extrapyramidal tracts are two of which of the following types of tracts of the spinal cord? A) Ascending tracts B) Descending tracts C) Lateral tracts D) Anterior tracts
A motor unit consists of: A) the alpha motor neuron and all the muscle fibers it innervates. B) all the alpha motor neurons activated for a specific movement. C) the alpha and gamma motor neurons associated with each muscle involved in a specific movement. D) all the gamma motor neurons activated for a specific movement.
Carson and Kelso demonstrated that to fully understand the neural correlates of motor control, in addition to identifying brain region and muscle innervation characteristics, we need to know: A) Movement force characteristics B) Peripheral nervous system involvement C) Action goals of the movements D) Individual difference characteristics of the performer of the movements
The _____ are extensions from the neuron's cell body that are primarily responsible for receiving information from other neurons.
The thin tissue of nerve cells that covers the cerebral cortex is call _____ matter.
The most posterior lobe of the cerebral cortex, which is especially important for visual perception, is the _____ lobe.
The areas of the cerebral cortex that would interconnect the various cortex areas needed to perform a choice reaction time task are known as the _____ areas.
Parkinson's disease is caused by a lack of production of _____ by the substantia nigra.
The nervous system contains fewer sensory neurons than either motor neurons or interneurons.
The primary motor cortex is the area of the cerebral cortex primarily responsible for movement initiation and the coordination of movements for fine motor skills.
Most of the extrapyramidal tract fibers crossover in the brainstem to the opposite side of the body.
