Components needed to respond to stimuli
When responding to a stimuli 5 components are needed: 1) receptors, 2) sensory nerves (afferent peripheral nerves), 3) central nervous system, 4) motor nerves (efferent peripheral nerves), 5) effectors
Receptors convert information such as light, sound and heat to action potentials. The sensory nerves (afferent peripheral nerves) transfer the action potentials to the central nervous system. The central nervous system processes the information (saving, thinking, judging, ordering, etc). The motor nerves (efferent peripheral nerves) transfer the information to the effectors. The effectors do the job according to the order.
