FOCUS QUESTION

How is the nervous system organized and how does it send signals?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Nervous System divided into Central Nervous System.
  • Nervous System divided into Peripheral Nervous System.
  • Central Nervous System includes Brain.
  • Central Nervous System includes Spinal Cord.
  • Nervous System made of Neurons.
  • Neurons transmit Nerve Impulses.
  • Peripheral Nervous System gathers Senses.

How to read this map

Split the system into central and peripheral divisions, then see how neurons transmit impulses and the senses gather information.

Learning objectives

  • Distinguish the central and peripheral nervous systems.
  • Identify the brain and spinal cord’s roles.
  • Explain how neurons transmit impulses.
  • Connect the senses to the nervous system.
Review standard: Divisions were checked against standard secondary-school anatomy descriptions. Sources: OpenStax Anatomy & Physiology — The Nervous System.
