Circadian Rhythm Quiz

Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place

| Which of the following represents the largest region of the brain?1. the cerebellum2. the hindbrain3. the midbrain4. the forebrain

Axons that decussate between the pyramids of the medulla oblongata belong to the ________ tracts.

A. Which of the four major areas of the brain (cerebrum, diencephalon, cerebellum and brain stem) was obviously much larger in the human brain in the diagram than in the sheep brain? Why do these structures differ so dramatically?

1b. List and describe briefly the major structures of the brain, as presented in your textbook, including the function of those elements that are most related to psychoactive drug reaction.

4. A tract in the spinal cord would most likely be found in the white matter.

You may choose to respond to this assignment yourself or interview another person. We often hear people commenting that their “biological” or “social clock” is ticking. What are the settings on your social clock? At what age do (did) you expect to be married? Have children? If you do (did) not marry by this time, what would you do? If you were told that you could not have children, what would you do? How would the absence of a spouse and/or children impact your plans for the future?

Circadian rhythms occur every 24 hours; an example of a circadian rhythm is the sleep-waking cycle. We are diurnal animals who are active during the daytime and asleep at night, other animals are nocturnal they are active at night but asleep during the day. The circadian rhythm depends on the interaction of physiological and psychological processes to be tuned into the sleep-waking cycle so energy is provided when needed. As diurnal humans we have a fairly stable sleep pattern with the time we go to sleep and the time we wake up, this consistency suggests an internal mechanism controls sleep, endogenous pacemaker. However, this can be overridden by external factors, exogenous zeitgebers.

b.) What is the role of cortical brain regions (i.e., cerebellum, the anterior cingulate cortex, the supplementary motor area, and the right frontal operculum)

Dave Phillips - He says that we we created like a circle for ourselves during the winter and try to hide from the snow instead of embracing it like most countries and we do that by hiding indoors and hibernating. Hes canadasa weather man and he said that 2009 was Canada's warmest winter and he was surprised by all the canadians that were full of joy because they all did not want a cold snowy winter. There were interviews on people on what they think of this year's winter and they were all happy, most of them were not even wearing winter jacket. Dave Phillips suspecting everyone to be disappointed but

“As some of the ice melts permanently and the quality of the remaining ice worsens, the penguins’ breeding grounds become endangered. If the ice melts before the chicks have had a chance to grow their waterproof adult feathers, the chicks won’t survive.” It proves that sea ice in Antarctica greatly affects the penguin population.

Describe the four lobes of the brain. Include the following information in your essay. (250 words)

Mothers care for their young chicks and protect them with the warmth of their own brood pouches. Outside of this warm cocoon, a chick could die in just a few minutes. In December, Antarctic summer, the pack ice begins to break up and open water appears near the breeding site, just as young emperor penguins are ready to swim and fish on their own.

The general argument made by MANNVI SINGH in her work is to providing informations and warning parents or teachers to be able to pick up early symptoms of teenagers are lack of sleep time. More specifically, the author is trying to make a point that's most of the kids have this are because of the environmental interaction that they lived in, it's typically like saying it's not the kids fault to have Circadian Rhythms. In the author work, she said that "depression symptoms weren't only showed in teens are engaging in risky behaviors"(by SINGH). In this passage, the author is suggesting that parents should have a dark room. This will likely to help the kids to not having mental problems in their early teens by cutting out their way to associate

The part of the brain that caught my attention that made me want to learn more was the Hypothalamus. The Hypothalamus is an almond shaped part of the brain that is quite intriguing as it has many different types of jobs that help us function in our everyday life. Do not let the size of the Hypothalamus fool you as it plays a huge part in our body’s internal balance system. In this paper I would like to talk about a few different topics on the hypothalamus. I would like to talk about the location of the hypothalamus, what the hypothalamus’s responsibilities are, how the hypothalamus sends and receives messages and how the hypothalamus communicates with other parts of the brain. I was in shock when I found out that something as small as an almond, played such a huge part in our day to day life.
