Document Summary

Part a communication & organization in the nervous system. Biological basis of behaviour: chapter 3 contains eight main sections, 1 . Evolution of behaviour: chapter 3 contains eight main sections, 1 . Hardware of the brain: neurons: brain cells that facilitate all processes by communicating via networks. The soma, or cell body, contains the cell nucleus and much of the chemical machinery common to most cells: 2. Dendrites are the parts of a neuron that are specialized to receive information. The axon is a long, thin fibre that transmits signals away from the soma to other neurons or to muscles or glands: 4. The myelin sheath is insulating material, derived from glial cells, that encases some axons. Terminal buttons are small knobs that secrete chemicals called neurotransmitters: 6. A synapse is a junction where information is transmitted from one neuron to another. The resting potential of a neuron is its stable, negative charge when the cell is inactive.
