Evidence is growing that glial cells also play an active role in the signaling and communication of info between neurons. 3 Types of neurons Sensory : they convey info about the environment, such as light or sound, from specialized receptor cells in the sense organs to the brain. Motor : communicate info to the muscles and glands of the body to relax or contract Interneurons (related to reflex arc and perception): communicate info between neurons.

Neurons: 3 main parts Cell body : provide energy for the neuron to carry out its functions Dendrites : receive info from other neurons & sensory receptors Axon ; carries neuron’s message to other body areas Myelin sheathing : is present on the axons of some neurons & increases neuron communication speed. Multiple sclerosis (MS): a disease that involves the degeneration of patches of the myelin sheath.
