Document Summary
It is the study of psychological, evolutionary and developmental mechanisms. Biological psychology includes neuroscience, behavior genetics, neuropsychology and evolutionary psychology. All of these explore how the nature of mind and behavior is rooted in our biological heritage. Our study of the biology of the mind begins with the neurons. Are neurons that carry incoming information from the sensory receptors to the brain and spinal cord: interneuron. Are neurons within the brain and spinal cord that communicate internally and process information between the sensory inputs and motor outputs. Neurons are formed of: soma, the cell body. It is made of: nucleus, ribosomes, mitochondria, dendrites, greek word for tree. Are the branching fibers that get narrower near the end, they receive information via synaptic receptors from other neurons: axon, greek word for axis. The sequences of chemical events are: synthesis. Transmitter molecules are stores in synaptic vesicles, in the axon terminal: release. Transmitter molecules move from synaptic vesicles across the cleft: binding.
