Nervous System Structure and Function

Explain how the structural adaptations of the human nervous system enable the coordination of behaviour and reactions to surroundings.
Describe the pathway of information from receptors to the central nervous system (CNS) via electrical impulses along neurones.
Outline the role of the CNS (brain and spinal cord) in coordinating the responses of muscular or glandular effectors.
Detail the sequence of events in a nervous response: stimulus, receptor, coordinator, effector, and response.
Explain the function and relationship of structures within a reflex arc, including sensory neurones, synapses, relay neurones, and motor neurones.
Understand the importance of reflex actions as rapid, automatic responses that bypass the conscious areas of the brain.
Extract, interpret, and translate numerical and graphical data concerning nervous system functioning and reaction times.
Plan and conduct a practical investigation to determine the effect of a specific factor on human reaction time.
