Structure and Function of Neurons
- The nervous system. (n.d.). Retrieved from http://www.sparknotes.com/psychology/psych101/thebrain/section1.rhtmlThe nervous system is a complex, highly coordinated network of tissues that communicate via electro chemical signals. It is responsible for receiving and processing information in the body and is divided into two main branches: the central nervous system and the peripheral nervous system.

Retrieved from http://allpsych.com/psychology101/neurotransmitters/#.VgITkJ2qqkoA Neuron is a specialized nerve cell that receives, processes, and transmits information to other cells in the body. We have a fixed number of neurons, which means they do not regenerate. About 10,000 neurons die everyday, but since we start out with between ten and 100 billion (Hooper & Teresi, 1987), we only lose about 2% over our lifetime.

Neurons - Key Terms
- axon noun - the appendage of the neuron that transmits impulses away from the cell body.
- cell body noun - the compact area of a nerve cell that constitutes the nucleus and surrounding cytoplasm, excluding the axons and dendrites.
- dendrites noun - the branching process of a neuron that conducts impulses toward the cell.
- myelin sheath noun - a wrapping of myelin around certain nerve axons, serving as an electrical insulator that speeds nerve impulses to muscles and other effectors.
- neuron noun - a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites.
- neurotransmitter noun - any of several chemical substances, as epinephrine or acetylcholine, that transmit nerve impulses across a synapse to a postsynaptic element, as another nerve, muscle, or gland.
- receptors noun - Cell Biology. any of various specific protein molecules in surface membranes of cells and organelles to which complementary molecules, as hormones, neurotransmitters, antigens, or antibodies, may become bound.
