Short explanation
In the subtopic The eye (biology only), this learning objective focuses on identify the retina, optic nerve, sclera, cornea, iris, ciliary muscles, suspensory ligaments and lens in the eye. 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 ciliary muscles, cornea, eye, iris, and lens. retina means the light-sensitive layer at the back of the eye that contains receptor cells sensitive to light intensity and color. Avoid students often confuse the functions of the cornea and the lens, thinking both are responsible for focusing light; instead remember that the cornea is primarily responsible for refracting light as it enters the eye, while the lens adjusts its shape to fine-tune the focus for near or distant objects. For exam answers, create a labeled diagram of the eye, including all key structures such as the retina, optic nerve, sclera, cornea, iris, ciliary muscles, suspensory ligaments, and lens.

- 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
- Explain why reflex actions are automatic and rapid protective responses that do not require conscious thought.
