Document Summary

Chapter 2: structure and function of the nervous system. How do we understand drug action: need to know about individual nerve cell structure and electrochemical function, have an essential understanding of how these individual cells form the complex circuits that represent the anatomical basis for behavior. Characteristics of the cells determine the structure and function of the tissue or organ: how did they become specialized, we look at embryonic stem cells. Nervous system is composed of embryonic stem cells that become nerve cells (neurons) and supporting glial cells (metabolic support, protection, & insulation for neurons) Neuron transmit info in the form of electrical signaling: sensory neurons sensitive to environmental stimuli convert the signal to electrical and transmit it to circuits of interneurons (nerve cells within the brain and spinal cord) Interneurons conscious sensations, recognition, memory, decision making, and cognition. Motor neurons direct a biobehavioral response.
