Motor System Quiz

Which part of the brain is responsible for initiating and executing movements?

• Cerebellum

• Basal Ganglia

• Motor Cortex

• Reticular Formation

What is the primary motor cortex responsible for?

• Controlling core body muscles

• Inhibiting unwanted movements

• Relaying commands to lower motor neurons

• Planning voluntary actions

Which pathway carries voluntary movement information from the cerebral cortex to the spine?

• Vestibulospinal tract

• Rubrospinal tract

• Corticospinal tract

• Reticulospinal tract

What is the function of the rubrospinal tract in humans?

• Direct torso and trunk muscles

• Carry voluntary movement signals to the limbs

• Compensate for changes in balance

• Control of muscle tone

Which motor pathways are responsible for posture and balance?

• Vestibulospinal, Tectospinal, and Reticulospinal tracts

• Corticospinal and Rubrospinal tracts

• Dorsal Column Medial Lemniscus System

• Anterolateral System

What is the role of the basal ganglia in movement?

• Initiating and executing movements

• Facilitating smooth and fluid movement

• All of the above

• Suppressing unwanted movements

Which diseases are associated with damage to the basal ganglia?

• Epilepsy and Schizophrenia

• Alzheimer's disease and Multiple sclerosis

• Parkinson's disease and Huntington's disease

• Stroke and Traumatic brain injury

What is the function of the vestibulospinal tract?

• Compensate for changes in spin or force on the head

• Direct torso and trunk muscles

• Control facial muscles for voluntary movement

• Provide information about gravity and body position

Which brain structure is responsible for coordinating sequences of movements?

• Motor Cortex

• Cerebellum

• Basal Ganglia

• Reticular Formation

What is the primary function of the cerebellum?

• Initiating and executing movements

• Controlling core body muscles

• Planning voluntary actions

• Coordinating and fine-tuning movements
