L33 Psych 100B Chapter Notes - Chapter 3: Central Nervous System, Resting Potential, Peripheral Nervous System
Document Summary
Neurons the basic units of the nervous system; cells that receive, integrate, and transmit information in the nervous system. They operate through electrical impulses, communicate with other neurons through chemical signals, and form neural networks. Neurons communicate selectively with other neurons to form circuits, or neural networks. Central nervous system (cns) the brain and the spinal cord. Peripheral nervous system (pns) all nerve cells in the body that are not part of the central nervous system includes the somatic and autonomic nervous system. Sensory neurons one of the three types of neurons; these neurons detect information from the physical world and pass that information to the brain. Somatosensory nerves the sensory nerves that provide information from the skin and muscles. Motor neurons one of the three types of neurons; these neurons direct muscles to contract or relax, thereby producing movement. Interneurons one of the three types of neurons; these neurons communicate within local or short-distance circuits.
