Document Summary

The study of the connection between biology and behavior. Your brain interprets that stimulus and signals are sent to other parts of your body. Your heart rate increases, you become more alert, muscular movements enable you to catch (or duck!) the candy. The point: behavior depends on rapid information processing within your nervous system. The nervous system is living tissue composed of cells. Neurons: nerve cells that receive, integrate, and transmit info. Basic building blocks of the nervous system. Carry messages from sensory organs to spinal cord or brain. Carry messages from the spinal cord to muscles and glands. Carry messages from one neuron to another. Tie us to others" actions and feelings. Axon: transmits info away from the soma to other neurons. Myelin sheath: insulates axons, speeds up transmission. Multiple sclerosis (ms) occurs when myelin layer is destroyed. Synapse: junction where info is transmitted from one neuron to another.
