Examples
- The motor fiber transmitted the brain's signal to the muscle, allowing it to contract and move the arm.
- Motor fibers are often bundled together in nerves to form larger pathways that enable coordinated movement.
- Damage to a motor fiber can result in muscle weakness or paralysis, depending on the location and severity of the injury.
- The motor fiber's job is to deliver the electrical signal from the central nervous system to the muscle, triggering a response.
- In reflex actions, motor fibers enable the body to react rapidly to stimuli by bypassing conscious thought and sending direct signals to the muscles.
