A nerve cell that carries messages is called a neuron ( figure below ). Its function is to produce the myelin sheath that insulates axons in the peripheral nervous system. A neuron consists of two major parts: Learning and memory require the coupling of information from many different brain regions. Yet the synapses alone store recollections of only the most.

Neurons have a unique elongated shape and consist of three main parts: A synapse is the space between neurons. Nerve impulses such as pain signals travel slower at 0.61m/s. Large myelinated nerve fibres conduct impulses rapidly, whereas nonmyelinated fibres conduct impulses quite slowly (figure 10.1). Nerve impulses can travel very quickly because they are electrical impulses.
