1. Chapter 34 Opener Chapter 34: Neurons and The Nervous System

2. Concept 34.1 Nervous Systems Consist of Neurons and Glia Parts of a neuron Define EACH of the following terms regarding a neuron. Be sure to include the function of each: Axon Axon hillock Axon terminal Cell body Dendrite Nucleus Presynaptic cell Postsynaptic cell Synapse

3. Concept 34.1 Nervous Systems Consist of Neurons and Glia What do axons do? a. The major function of an axon is to transmit electrical signals from one location to another. b. Axons are the primary location where a neuron receives information from other neurons. c. Axons manufacture neurotransmitter. d. Axons are the primary location where a neuron releases neurotransmitter. e. All of the above
