Document Summary
The biology of behaviour: the brain and our genes. Perception is a function of our brain and nervous system. Constant exchange of information from our environment to our brain, our brain to our body, and back to the brain. Central nervous system the brain, the spinal chord. Cerebrospinal fluid protects cns from injury and nourishes the brain, the brain floats in it. Chemical stability rinses metabolic waste from cns to maintain ph levels. Spinal chord bundles of axons transmit neural impulses from brain to peripheral nerves and vise-versa. The brain the information processing center. Neurons cells of the nervous system that receive and relay information throughout the body. Dendrites pick up signals from other neurons. Axon (not all neurons have it) messages passed along it to other neurons. Myelin sheath makes brain tissue appear white, insulates the axon, makes electrical impulses move faster. Glial cells provide structural support for neurons.
