Document Summary
Biol 273-chapter 8: neurons: cellular and network properties notes. Nervous system: a network of billions of nerve cells linked together in a highly organized manner to form the rapid control system of the body. Neurons: carry electrical signals rapidly and in some cases over long distances. Emergent properties: complex properties, such as consciousness, intelligence, and emotion that cannot be predicted from what we know about properties of individual nerve cells and their specific connections. Enteric nervous system: a network of neurons in the walls of the digestive tract. Multipolar: has many dendrites and branched axons. Pseudounipolar: neurons have the cell body located off one side of a single long process that is called the axon. Bipolar: neurons have a single axon and single dendrite coming off the cell body. Anaxonic: neurons lack an identifiable axon but have numerous branched dendrites. Varicosity: swollen regions along autonomic axons that store and release neurotransmitters.
