Overview of nervous system (chapter 9 of textbook) Central nervous system (cns): consists of brain and spinal cord. Peripheral nervous system (pns): nerve fibers that transmit signals between the cns and organs in other parts of the body. Fibers grouped into bundles called nerves: 43 pairs of nerves. Grey matter contains of cell bodies of neurons. White matter in the sc consists of nerve fibers carrying information to and from the brain. Tracts: carry bundles of nerve fibers with common purpose. Parietal lobe: interprets sensory information from skin, contains primary sensory centre. Temporal lobe: interprets auditory information, comprehends language, perceptual judgment. Frontal lobe: initiates motor activity, responsible for speech, conscious thought.
