NERVOUS SYSTEM

• sensory neuron- carry information from receptors to CNS
• motor neuron- carries impulse from the CNS back out to an effector
• neurones- long and thin, carry electrical impulses, branches connecting to either end passing messages
• neurone - neurotransmitter - neurone
• synapse- connection between cells, chemical diffuses, triggering another electrical impulse
• CP: drop ruler, measure distance fallen before caught, repeat and calculate a mean
• reflex arc- bypasses brain, rapid, automatic
