Question

For Module #2 our insight into Psych assignment will revolve around the biological processes that relate to the study of psychology. We've covered a lot of ground during this module and I would like to take a moment to connect some of the concepts we've discussed. Based on what you've learned during this module, answer the following questions. Each question is worth 10 points. The word count for each of the five questions should be at least 200 words. 1. Explain how communication occurs within neurons and between neurons 2. In your own words, describe the subdivisions of the nervous system and what they do. . Describe at least five (5) ways in which biology influences human behavior. 4 Popular culture has taken many psychological experiments out of context. For example, Sperry's "Split Brain" experiment has led many to inaccurately believe that the right side of the brain is "creative," while the left side of the brain is "logical." Explain why people would have come to that conclusion. In other words, what was it about Sperry's experiment that pointed to that outcome? 5. The medical use and legalization of marijuana has sparked ongoing debate about how the drug affects the brain. Explain how marijuana affects human cognition and behavior. What are possible consequences of the use of marijuana as it relates to our employment, education, and general behaviors and cognitions?

Explanation / Answer

2.The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. The central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system. Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component; and the autonomic, or involuntary, component. The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort. The autonomic nervous system is further subdivided into the sympathetic and the parasympathetic nervous systems. The sympathetic nervous system is activated in cases of emergencies to mobilize energy, while the parasympathetic nervous system is activated when organisms are in a relaxed state. The enteric nervous system functions to control the gastrointestinal system. The somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin. The somatic nervous system is the system that helps the body adjust to the external environment through the voluntary movement of the skeletal system. Some examples of the somatic nervous system include: the blinking reflex, knee jerk reflex, gag reflex, and the startle reflex and rooting reflex in infants.
