Nervous system cells. Nerve potentials. Synaptic transmission. Features of neurons. Neurons Neurons are cells that transfer information within the nervous system. Three classes of neurons: Sensory : Transmit information from sensory receptors to the brain. Motor : Transmit commands from the brain to the muscles and glands of the body. Interneurons : Interconnect neurons. Glia Glia support the neurons of the brain. Provide insulation. Remove waste products and foreign bodies. Recent research suggests their role may be more complex than previously thought. There are about 10 times as many glia as neurons. A glial cell is only about 1/10 the size of a neuron. Components of the Neuron: Functions Dendrites : receive information from other neurons. Cell body : creates transmitter molecules. Axon Myelin insulates the nerve cell, speeds up conduction of nerve messages. Terminal buttons
