Physiological Psychology Summary Chapter 2 On this chapter, we can find more detailed information about the nervous system, and its different structures and functions. There are three different types of neurons discussed in this chapter. Those neurons are the Sensory Neuron, which is a neuron that detects changes in the external or internal environment and sends information about these changes to the central nervous system. The motor neuron that is a neuron located within the central nervous system that controls the contraction of a muscle or the secretion of a gland. It also sends information away. And the Interneuron that is a neuron located entirely within the central nervous system. The peripheral nervous system is the nervous system that is immediately outside of the brain and the spinal cord, which in turn, is the central nervous system. The structure of a neuron is that of a soma (the cell body), the dendrite (receives information from the terminal buttons and from other neurons), the synapse (the junction between a terminal button and a axon), and an axon (relays information from the soma to its terminal button). Furthermore, there are multipolar neurons, a neuron with one axon and many dendrites. Bipolar neuron is a neuron with one axon and one dendrite attached to its soma and unipolar neuron which is a neuron with one axon attaches to its soma; the axon divides one branch receiving sensory information and the other sending information into the central nervous system. We also identified the Corpus Callosum as a bundle of nerve fibers running to various organs and tissues of the body, uses electrical and chemical signals to transmit sensory and motor info. Connection, it makes it or breaks it, spread or disorder. A solution for severe seizures is to separate the corpus callosum.
