Nerve+Transmission+and+the+Reflex+Arc

The nervous system is a network of nerve cells that carry messages called impulses. The region where nerve impulses pass from one neuron to another is the synapse. A receptor are the specialized structures that are sensitive to certain stimuli. Effectors respond to a stimulus. The axon is a long, thin fiber that extends from the celll body. They are surronded by the schwann cells. The axon carries impulses away from the cell body.

The reflex are is is a neural pathway that controls an action reflex. There are two types of reflex arc - autonomic reflex arc (affecting inner organs) and somatic reflex arc (affecting muscles).
