Quick explanation
Explain that the brain and spinal cord form the central nervous system
- This point belongs to The human nervous system, especially Structure and function.
- You need to be able to explain that the brain and spinal cord form the central nervous system.
- The key ideas to know are spinal cord, brain, and nervous system.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Structure and function to exam-style questions, flashcards, and revision notes for The human nervous system.
Quick student answer
How do you explain the brain and spinal cord form the central nervous system?
Direct answer
In Biology, this page helps you answer questions about the brain and spinal cord form the central nervous system within The human nervous system. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are central nervous system and spinal cord.
Key terms
- central nervous system: The part of the nervous system that consists of the brain and spinal cord, responsible for processing information and coordinating responses.
- spinal cord: A long, thin bundle of nervous tissue that extends from the brain down the back, transmitting signals between the brain and the rest of the body.
Common trap
Misunderstanding CNS Components: Emphasize that both the brain and spinal cord work together as the central nervous system, coordinating all nervous system activities.

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
- Describe muscles and glands as effectors that bring about responses, with muscles contracting and glands secreting hormones.
