Document Summary

1) let"s look at signal transmission in a simple neural circuit: knee jerk reflex loop. Cns sends command out to tell our body. Sensory neuron brings in the tapping signal. In the center of the spinal cord it will make a synapse with the motor neuron to tell the motor neuron something has happened by releasing the skills. Motor neuron gets the signal chemical signal transmitted into electrical signal. Within the neuron is an electrical signal, receiving from other neurons is a chemical signal. Motor neuron will have the electrical signal down reaches the end interacts with muscle which is chemical. Neurons are separated must solve gap problem. Electrical and chemical are two forms of signal transmission. Chemical signal will turn into an electrical signal. If there is enough postsynaptic potential it will become an action potential and that will send down.
