An introduction to the human nervous system including the central nervous system (brain and spinal cord), peripheral nervous system, and including the reflex arc and response time experiments Doc Brown's biology exam revision study notes This page will answer many questions e.g. What do we mean by a sensory organ? What are your five sense organs? How are signals from sensory organs sent to the brain? What is a synapse? What is a sensory neuron? Sub-index for this section on the nervous system
See also The brain - what the different parts do and the dangers if damaged Any practical work and investigations you did should also be revised (which should also be revised, helps in understanding 'how science works' and context examination questions):
