This comprehensive lesson explores the structure and function of the nervous system, introducing learners to neurons, nerve pathways, the central and peripheral nervous systems, and the major regions of the brain.

Students investigate how messages are transmitted throughout the body, examine the different types of neurons, and compare the sympathetic and parasympathetic divisions of the autonomic nervous system. The lesson then develops understanding of brain anatomy, including the forebrain, midbrain and hindbrain, before exploring the functions of key brain structures and cerebral lobes.

A range of diagrams, labelling activities, discussion tasks and retrieval exercises are included to support understanding of complex anatomical concepts.

Learning Objectives:
Describe the structure and function of neurons.
Identify the components of the central nervous system (CNS) and peripheral nervous system (PNS).
Differentiate between sensory, relay and motor neurons.
Explain the roles of the sympathetic and parasympathetic nervous systems.
Identify major regions of the brain.
Describe the functions of key brain structures and cerebral lobes.
