PSY 750 Chapter Notes - Chapter 1: Autonomic Nervous System, Peripheral Nervous System, Myelin
Document Summary
The human nervous system, the central and peripheral nervous systems. Differentiate between the somatic and autonomic nervous systems. Which autonomic nervous system would activate responses under times of relaxation: building blocks of nervous system: neurons. Describe the three different types of neurons and their primary function. Describe the four functional structures of a neuron (dendrite, soma, axon, and terminal buttons), and describe what they do. Distinguish between depolarization and hyperpolarization, and relate them to the electrical potential of the neuron. Differentiate between the absolute and relative refractory periods. Describe what happens at the synaptic cleft as an action potential travels along the pre-synaptic neuron. Name 3 different neurotransmitters found in the nervous system, and briefly describe their function. The brain control of behavior: brain structures and their function. In general, describe the function of the midbrain structures. Describe and briefly summarize the function of each of these forebrain structures: the cerebral cortex, thalamus, hypothalamus and limbic system (amygdala and hippocampus).
