Question

devi is riding a motorcycle to work. when devi hears the honking of a truck trying to overtake her, she gives way to the truck. in the context of the pathways in the nervous system, which type of nerves communicated information from devi’s brain to her muscles and made her move the motorcycle?

○ olfactory nerves

○ pyramidal nerves

○ efferent nerves

○ afferent nerves

Explanation:

• Olfactory nerves are for smell, not motor control.
• Pyramidal nerves are part of motor pathways but the broader category for carrying signals from brain to muscles (effector organs) is efferent nerves.
• Efferent (motor) nerves transmit signals from the central nervous system (brain) to muscles/glands to produce action (like moving the motorcycle).
• Afferent nerves carry sensory info to the brain, not motor commands out.

Answer:

C. efferent nerves
