PSYA01H3 Chapter Notes - Chapter 3: Autonomic Nervous System, Neuroglia, Peripheral Nervous System
Document Summary
Neurons work by forming circuits and pathways in the brain, which in turn influence circuits and pathways in other areas of the body. Neurons are the building blocks that form nerves, or bundles of axons and the glial cells that support them. Nervous system an interacting network of neurons that conveys electrochemical information throughout the body. The spinal cord branches down from the brain; nerves that process sensory information and relay commands to the body connect to the spinal cord. Peripheral nervous system (pns) connects the central nervous system to the body"s organ and muscles o. The peripheral nervous system is itself composed of two major subdivisions. The somatic nervous system a set of nerves that conveys information into and out of the central nervous system. Humans have conscious control over this system and use it to perceive, think, and coordinate their behaviours.
