Pineal gland

endocrine system, it is made up of many different glands, but every gland still does a part in making sure that organs in the other body systems are well balanced. I liked the endocrine system when we went over it in class and thought it would be an excellent choice. Especially since most of it has to do with the brain and I love to study the brain. I will cover all the endocrine glands and many of the hormones they produce in this paper. The Endocrine glands carry secretions called hormones…

period. The hypothalamus is located in the brain and contains the superchiasmatic nucleus (SCN) which controls the circadian rhythm. The SCN controls sleep patterns by receiving visual cues from the visual system and passing signals to the pineal gland. The pineal gland, when signalled to, releases melatonin, a sleep hormone, which causes us to feel sleepy when it begins to get dark. This explains why we feel sleepy at night but feel more awake and alert during the day. Light, therefore,…

The human circadian rhythm is a vital part of a person’s internal clock system. “Circadian desynchrony, is a sleep disorder where there is a mismatch with the body’s natural circadian rhythm and external environment.” (Choy & Salbu, 2011) This argues the fact that by switching time zones and environments that the body is not accustomed to will lead to irregular sleep cycles. Specifically when the body is moved across over two time zones it will lead to the perceived symptoms of jet lag (Choy &…

Introduction to Philosophy (U73100) Title of essay: Is the Mind/Brain identity theory a defensible position? In this essay I will show that the mind/brain identity theory is the only logically defensible position when it comes to the mind/body problem. To do this I will be looking at the most popular arguments and positions concerning the mind body problem. I will begin by discussing what is meant by the term 'mind body problem', the mind body problem is a philosophical issue concerning…

Introduction The argument whether or not the mind and the body are distinct substances raises a still on-going debate. In this essay, I proceed to give evidence as to why the Cartesian dualism theory is flawed. First, I am going to introduce a few of Descartes’ arguments and his position on the matter. Then, I will try to pick his most appealing argument and put it up against logical reasoning and other philosophers’ viewpoints. Finally, I am going to conclude how Rene Descartes proposes…

difference between gyri and sulci. Some internal structures I struggled to point out was the hippocampus and the pineal gland, in the future, I would do a further analysis of the clear difference between these two features. Doing the dissection with my partners was very interesting and it was a lot easier to see the difference between most features on an actual sheep brain. We…

Case study one – (Explain how the musculo skeletal system structure is suited to the function it performs. (2.1) Mrs C is pregnant and wants to pick up a ball, describe in depth which parts of the musculo skeletal system are involved in this movement and which structural parts provide support and protection of the vital organs. The musculo skeletal system consists of bones of the skeleton, muscles, cartilage, tendons, ligaments and joints, they all work together to provide the body support,…

devalued. For example, Descartes believes that the body has no formal or final cause intrinsic to itself, which means that the body is just an organic machine meant to live and die. Secondly, the absence of causal powers means that the brain’s pineal gland, not the mind, (through interacting with “spirits” in the veins and a physiological union) controls bodily movements. This belief that the brain controls bodily movements is a difficulty with the Cartesian position of substance dualism because…

every 24 hour period. Our Circadian Rhythms reset about every 24 hours and sleep is needed during every one of these periods to keep our bodies working correctly. Our bodies are tired by night (or whenever our normal sleep time is) and our Pineal Gland (same gland that produces DMT)secretes Melatonin. Melatonin is a sleep hormone that our bodies produce when in it is time for us to go to sleep. Melatonin helps make us sleepy.…
