HBS Essential Questions 2.1

1. What is communication?
Communication is by definition the exchange of information between different places. In today’s society, people may relay information on the phone or in a conversation. Similarly, in the body, it is common that information needs to travel in order to make decisions or carry out decisions. For example, a person may touch something. The cells that sense contact would communicate the signal for what is being felt across the body to the brain; the person who touches a certain substance would then feel what was touched. This can happen in an instant and often times the body will use reflexes instead. Touch occurs so quickly, however, that time is vital if someone’s life is in danger. If a person were to touch a very hot substance, the body would immediately pull away before they can even have time to react or think. This evolutionary advantage can save someone’s life. Other areas of the body relay information as well. The brain is like the AT&T Headquarters of the body; it oversees all information passing between cells, by means of the blood stream, and often tells a certain area to release a signal or secrete a hormone – a chemical signal that allows for certain body functions to occur. However, unlike the game Telephone, the information that is shared between parts of the body is rarely changed and can allow the body to function properly. 2. What are ways communication occurs in machines and in the human body? The brain is made up of neurons that pass communication through the body. This process can be likened unto that of a machine. A machine needs all parts to function. Similarly, the body needs all of its parts in order to work properly. Also, if a machine has all of its parts, yet some small part of it is malfunctioning, the whole system will fail. This is the same in the body. On rare occasion, something may be altered or fair to translate in the body, which can cause the whole system to be inoperable. Machines are also very efficient; one single machine can produce thousands of items of merchandise. The body is very productive as well and is able to transfer hundreds of thousands of hormones and signals and impulses every day. Machines can also produce waste of sorts, such as air pollution. Our bodies digest and use substances until they can no longer profit from them. After all the beneficial parts of a food particle is completely used up, the body dispels the waste. 3. What are consequences of miscommunication in the body?

Miscommunication consequences vary depending on the area. Certain parts of the brain are responsible for performing certain tasks. Depending on the area, different bodily functions may be afflicted. If the brain is unable to work properly, the whole body faces the consequences. Yet if something less extreme occurs, such as a single kidney breaking down, the body may still be able to continue without great difficulty. In certain areas of the brain, a specific task is performed. For example, Phineas Gage was working on a railroad when a rod completely shot through his head. His frontal lobe was severely damaged. Because of the area of the brain in charge of personality, decision making, planning, etc. was severely damaged, various sorts of miscommunication occurred and Gage was never the same person though his body was able to remain functioning in other ways.

4. How do the central nervous system and the peripheral nervous system work together to control the body?

5. What are the functions of the main regions of the brain?
The main regions of the brain include:
*Frontal Lobe: Part of the brain responsible for reason, planning, movement, emotion, planning, and problem solving. *Temporal Lobe: The section of the brain that stores memory, allows speech, and interprets sound. *Parietal Lobe: Brain segment accountable for recognizing stimuli, movement, position, and recognition. *Occipital Lobe: Allows for visual processing and...
