What is the role of the motor homunculus in the brain?
It regulates emotions.
It maps motor control to different body parts.
It controls balance and posture.
It facilitates sensory feedback.
What part of the brain controls rapid eye movements (like when you're reading)?
Primary motor cortex
Frontal eye fields
Prefrontal cortex
Cerebellum
What is the term for the muscle contraction that occurs without conscious thought, like the knee-jerk reflex?
Involuntary movement
Reflex arc
Muscle tone
Proprioception
Which motor system dysfunction causes involuntary, repetitive movements like tics?
Dystonia
Chorea
Tourette syndrome
Ataxia
What is the term for a motor condition where a person has difficulty initiating movement?

What is the role of the pyramidal tract in the motor system?
It controls involuntary movements.
It refines motor actions.
It controls voluntary movements.
It balances the body.
Which side of the body does the left hemisphere of the brain control?
The left side of the body.
The right side of the body.
Both sides of the body equally.
The body's sensory functions.
In addition to movement, what other aspect of motor control does the basal ganglia influence?
Sensory input
Attention and motivation
Memory formation
Visual processing
What happens in the brain when you experience "writer's cramp" (a form of dystonia)?
The cerebellum becomes overactive, leading to uncontrollable movements.
The basal ganglia fails to regulate voluntary movements, causing muscle contractions.
The motor cortex stops sending signals to the muscles.
The spinal cord overcompensates for motor deficiencies in the legs.
What does the term "dyskinesia" refer to?
The inability to initiate movement.
Abnormal, involuntary movements often resulting from medication or brain disorders.
Difficulty with balance and coordination.
The process of learning motor tasks.
Why do people who have had a stroke sometimes experience weakness on one side of the body?
The motor cortex on the affected side of the brain is damaged.
The cerebellum is unable to coordinate movements.
The spinal cord can no longer send signals to the muscles.
The basal ganglia cannot regulate movement properly.
