Short explanation
In the subtopic Structure and function, this learning objective focuses on explain why reflex actions are automatic and rapid protective responses that do not require conscious thought. Within The human nervous system, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include reflex action. reflex action means an automatic and rapid response to a stimulus that occurs without conscious thought, designed to protect the body. Avoid students often think that reflex actions require conscious thought and decision-making; instead emphasize that reflex actions are automatic responses triggered by stimuli, allowing for rapid reactions without the need for conscious processing. For exam answers, memorize the characteristics of reflex actions, focusing on their automatic nature and speed.

- Describe the nervous system as a system that enables humans to react to their surroundings and coordinate behaviour.
Structure and function
- Describe the pathway in which receptor cells detect stimuli, sensory neurones carry impulses to the CNS, the CNS coordinates a response and motor neurones carry impulses to effectors.
Structure and function
- Explain that the brain and spinal cord form the central nervous system.
Structure and function
- Describe muscles and glands as effectors that bring about responses, with muscles contracting and glands secreting hormones.
Structure and function
- Describe a reflex arc using the sequence stimulus, receptor, sensory neurone, relay neurone, motor neurone and effector.
