The basal ganglia functions as a bridge between what two parts of the nervous system?

• A. Right and left hemispheres.
• B. Frontal and temporal lobes.
• C. Parietal and occipital lobes.
• D. Motor regions and spinal cord.

Answer: (D)

Verified step by step guidance

1. Understand the role of the basal ganglia in the nervous system. It is primarily involved in the regulation of voluntary motor movements, procedural learning, and routine behaviors or habits.
2. Recognize that the basal ganglia acts as a relay station, processing information from various parts of the brain and sending it to the motor regions to coordinate movement.
3. Identify the two main components involved in motor control: the motor regions of the brain, which plan and initiate movement, and the spinal cord, which executes these movements by transmitting signals to the muscles.
4. Consider the options given: Right and left hemispheres, Frontal and temporal lobes, Parietal and occipital lobes, and Motor regions and spinal cord.
5. Conclude that the basal ganglia functions as a bridge between the motor regions of the brain and the spinal cord, facilitating the smooth execution of movements.
