The human body has two signaling systems, the hormone system andthe nervous system to control body functions.
a) Describe the two systems
b) Why do we need two communication systems?
c) Do the two systems have evolutionarily the same origin?Justify your answer and give clear examples.
My teacher graded this with an E, saying that I am notidentifying and explaining in detail, clearly, and correctly, forthe two systems. And that I don't use correct and relevantterminology throughout. They are also saying that I don't have awell-developed and problematized justification with examples forboth communication systems. Additionally, in the discussion Ididn't present well-founded and nuanced arguments and give adetailed and nuanced account of the consequences of severalpositions, and didn't highlight relevant new question at issuesthat will guide the discussion forward.
What can I add to get a higher score?
My answer:
The nervous system causes information to be disseminated to thebrain by means of the nerves in the body that send signals to thebrain in the form of electrical stimulation, what can be sent tothe brain is that in case you are injured, the nerves signal to thebrain that you have been damaged itself. The nervous systemconsists of two parts, which are central and peripheral. The brainand spinal cord form the central nervous system, and there arevarious parts of the brain that cooperate with the nerves. Theperipheral nervous system is the nerves found in the body thatconnect to the brain and spinal cord and consists of the motor andsensory nerves, motor nerves are the nerves that are connected tomuscles, and sensory nerves convey signals from the sensory organsto our brain.
The hormone system is glands (e.g., thyroid glands,ovaries/testicles) that form substances that signal and sendinformation in the body and are transported with the blood. Thehormone system determines a person's growth, metabolism, sex drive,reproduction. Examples of hormones may be cortisol, which isproduced in the adrenal glands in stressful situations and causesblood pressure and pulse to rise and the trachea to open more,leading to the body being ready to handle dangerous situationswhere life is in danger. An important part of the hormone system isthe pituitary gland that controls the remaining glands and itshormone production and which sits in a small part of the brain, andbecause the pituitary gland forms its hormones, the remainingglands are stimulated to produce their hormones. It is said thathormones only affect certain cells and act as chemical informationsignals. In the testes, men have their sex hormones, and that isnecessary for men to develop the genitals, the hormone thatdevelops there is called testosterone while the woman has herhormones in the ovaries and there she has her estrogen, the femalehormones.
The communication systems are important because one needs toknow the body's need for survival, and this is where the hormoneand nervous systems help by sending signals from and to the brain,for example, Are hungry and need food or you are injured, the bodymust quickly send white blood cells to fight potential infections.For example, cortisol is important to produce in potential dangerwhile the brain signals the heart to pump blood faster via cortisolto send oxygen-rich blood to the muscles in order to strain them inanticipation of a potential threat to a dangerous animal. Theperipheral nervous system helps man to move joints and muscles, andfrom this, you can move, see things around and interpret thingswith the organs of the senses.
The nervous and hormone systems have the same origin because thenervous system records the body that is exposed to and the hormoneshelp to solve any problems the body is exposed by secretingimportant hormones that prepare the body for dangers such as thehormone cortisol, for example, everything that affects the nervoussystem causes a release of different hormones, and it is importantthat there is a balance with these hormones or else you can haveproblems in the body.
