Document Summary

Describe the anatomical and functional divisions of the nervous system. Describe the structure of a typical neuron, describe the functions of each component, and classify neurons on the basis of their structure and function. Describe the functions of the various types of neuroglia. Describe the structure of a synapse, and explain the mechanism involved in synaptic activity. Explain how the resting potential is created and maintained. Describe the events involved in the generation and propagation of an action potential. Discuss the factors that affect the speed with which action potentials are propagated. Neural tissue contains two kinds of cells: neurons, cells that send and receive signals, neuroglia (glial cells, cells that support and protect neurons. Sensory receptors of sense organs (eyes, ears, etc. ) Nerves connect nervous system with other systems. Anatomical divisions of the nervous system: central nervous system (cns, peripheral nervous system (pns) Consists of the spinal cord and brain. Contains neural tissue, connective tissues, and blood vessels.
