Document Summary

1. 2 the individual neuron and the organzation of the nervous. Several organ systems are important for biological basis of psychology: motor, digestive, endocrine, nervous system is particularly important, neurons are nerve cells, the basic cellular units of the nervous system, parts of the neurons: Soma: cell body, largest part, dendrite: Receiving pole: taking info in from other parts: types of info: physical or chemical, axon (can be covered with myelin): Very long extension of the nerve cell. At the neon of each branch, there are terminal. About 70 billion neurons in our brain. Interconnected: neurons are electrically and chemically active, generate electrical impulses, can measure electrical activity, electrical activity. Action potentials : neurons go into hyper extensive state. Chemical signaling release of chemicals on other neurons: signal to each other using chemical transmission, chemicals usually neuro transmitters. The synapse is the point of functional connection between two neurons: there is a gap called the synaptic cleft, which separates two neurons.
