What neurotransmitter is crucial for smooth motor function and is deficient in Parkinson’s disease?

• Dopamine

• Serotonin

• GABA

• Acetylcholine

What is the name of the motor pathway responsible for precise, fine motor skills like writing?

• Rubrospinal tract

• Corticospinal tract

• Reticulospinal tract

• Vestibulospinal tract

What is the term for the reflex that occurs when you touch something hot and immediately withdraw your hand?

• Patellar reflex

• Stretch reflex

• Withdrawal reflex

• Crossed extensor reflex

Which cranial nerve controls the movement of most of your eye muscles?

• Optic nerve

• Oculomotor nerve

• Trigeminal nerve

• Facial nerve

What is the name of the condition where damage to motor neurons leads to muscle weakness or paralysis?

• Huntington's disease

• Amyotrophic lateral sclerosis (ALS)

• Multiple sclerosis

• Parkinson’s disease

What is the term for the inability to perform coordinated movements, often caused by cerebellar damage?

• Ataxia

• Dysarthria

• Apraxia

• Dystonia

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
