Describe the role of the nervous system in facilitating reflex actions.

The nervous system facilitates reflex actions by providing a pathway that includes sensory neurones, relay neurones, and motor neurones. When a stimulus is detected, sensory neurones transmit impulses to the central nervous system, where the response is coordinated and sent through motor neurones to the effectors, resulting in a rapid response.

This answer effectively outlines the sequence of events in a reflex action, demonstrating an understanding of the nervous system's role. The question tests the student's ability to apply their knowledge of the nervous system's structure and function in the context of reflex actions.
