Document Summary
Neurons and the nervous system: nervous system chart, neurons, action potential, synapses. To illustrate this system in action, consider the following two situations: touching a hot iron sensory neurons detect the heat and send an excitatory message to inter-neurons in the spinal cord or brain. These inter-neurons then send excitatory signals to the motor neurons to retract the hand immediately: carrying a hot casserole dish again, the heat may make you want to drop the dish via the same process described above,
