Document Summary
Chapter 6: neuronal signaling and the structure of the nervous system. These cells communicate with each other by electrical and chemical signals. They maintain homeostasis by coordinating functions of internal organs, as well as mediating. Together they regulate most internal functions and organize and control the activities we know collectively as human behavior. Nervous system is composed of trillions of nerve cells distributed in a network throughout the brain, spinal cord, and periphery sensation, controlling movements, and encoding the mind. 2 parts cord with the body"s muscles, glands, and sense organs. The basic unit of the nervous system is the individual nerve cell, or neuron. Neurons operate by generating electrical signals that move from one part of the cell to another part of the same cell or to neighboring cells. In most neurons, the electrical signals causes the release of chemical messengers (neurotransmitters) to communicate with other cells.
