 * [[file:Savannah, Kierra, Melissa's project.ppt]]**__Neuron__** is a nerve cell and the basic structure of the nervous system.
 * What are the parts of a neuron and what do they do?
 * Cell bodies - The center for receiving and sending nerve pulses.
 * The Axon - Specialized to carry messages.
 * The Dendrites - Specialized for receiving impulses. Mostly from axons and axons from other neurons.
 * Myelin Sheath - Fatty cells that wrapped around the axon many times.


 * What are neurotransmitters / What do they do?
 * Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses.


 * Sketch a basic neuron and label the parts. [[image:http://www.enchantedlearning.com/subjects/anatomy/brain/gifs/Neuron.GIF width="535" height="308"]]


 * **__ Nerves __** are bundles of axons or dendrites bound together by connective tissue. They are composed of several neurons. There are three main types (check you text book) of neurons. What are they and how are they different from each other?
 * the three main types of neurons are sensory neurons, interneurons, and motor neurons.
 * ===Sensory:run from the various types of stimulus receptors===
 * ===Interneurons:are found exclusively within the spinal cord and brain. They are stimulated by signals===
 * ===Motor neurons:transmit impulses from the central nervous system to the muscles and glands===
