Document Summary

Week 7: chapter 4: biology of behaviour: 86-125. Brain has 3 major functions: controlling behaviour processing/retaining information from environmental stimuli regulating body"s physiological processes. Nervous system divides into 2 parts, the cns and pns. Central nervous system communicates with body through nerves. Vertebra: bones encasing spinal cord, consitutes vertebral column. Meninges: three-layered set of membrane enclosing brain & spinal cord. Cerebrospinal fluid (csf): liquid filling space between two of the meninges, in which brain & spinal cord float protecting/cushioning them. Divides into: autonomic nervous system (ans)- uncontrollable behaviour sympathetic nervous system- fight/flight response parasympathetic nervous system- state of calm/digestion skeletal nervous system. Dendrites: branch-like growths attached to nerve cell body transmit electrochemical impulses to the nerve cells neurons in the brain have nerve cells that contain dendritic spines on the surface of dendrites. Soma: cell body, largest part of the neuron controls metabolism and maintains the cell in most cells, receives messages from other neurons.
