How do the CNS and PNS differ?
Expert Solution & Answer
Summary Introduction
To analyze:
The difference between CNS and PNS.
Introduction:
The nervous system is defined as the system, which controls all the body movements of a living organism. In humans, the nervous system is divided into two main division, central nervous system and peripheral nervous system.
Explanation of Solution
The components of the nervous system are located throughout the body. The brain is regarded as the central processing unit of the nervous system. The differences between the central nervous system and peripheral nervous system is given below:
| Central nervous system (CNS) | Peripheral nervous system (PNS) |
| It is composed of spinal cord and brain. Responsible for integrating and coordinating the information. It is the location of functions such as learning, memory, emotions, and intelligence. The damage to the CNS can affect all the body. | It is composed of network of nerves present outside the brain and spinal cord. It is spread throughout the body. It is responsible for detecting the stimulus and link the CNS to the body. The damage to the PNS causes local damage. |
Conclusion
The CNS is the central processing unit of the nervous system. The PNS is the link between the CNS and body.

What objects or events has the team chosen to analyze?
How does your team wish to delineate the domain or scale in which these objects or events operate? How does that limited domain facilitate a more feasible research project?
What is your understanding of their relationships to other objects and events? Are you excluding other things from consideration which may influence the phenomena you seek to understand? Examples of such exclusions might include certain air-born pollutants; a general class of water bodies near Ottawa, or measurements recorded at other months of the year; interview participants from other organizations that are involved in the development of your central topic or issue.
In what ways do your research questions follow as the most appropriate and/or most practical questions (given the circumstances) to pursue to better understand…
The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2).
Which of the following claims is most consistent with the data shown in Figure 2 ?
A Esp expression is necessary to prevent the overproduction of insulin.
B Esp protein does not regulate blood-s
