Free Essays on Hobbit

The Hobbit The Hobbit by J.R.R. Tolkien takes place in a world of pure fantasy. This amazing new world has differences, as well as similarities, to our world. This fantasy world, Middle Earth has been created using both Tolkiens imagination and details of reality from our own world. By incorporating these realistic elements of our world into the book, the author allows the reader to find a common thread with the characters and their surroundings. Most of the differences between Middle Earth and today's world are found in creatures and their actions that can not be found or enacted in our world. One of the best examples of this in The Hobbit is the presence of magic. Gandalf, the wizard, is able to help the characters out of a large amount of dangerous situations by using his magical powers to hurt or destroy their enemies. He set Wargs on fire while they were trapped in a tree and made a bolt of lightening to kill many of the Goblins who had surrounded the group in a cave. The magical ring, which was an important in helping the group survive in the book, allowed he who was wearing it to become invisible to others. Also, there was a black stream in Mirk wood that made anyone that drank out of it suddenly very tired and forgetful of what had just happened. All of these examples of happenings and objects found in Middle Earth are impossible in the world as we know it. Several of the species in the book do not exist on Earth. Hob bits, of course, are fictional characters, along with the dwarves, elves, goblins, and trolls. Many species of animals are able to vocally communicate with humans and dwarves in the novel, which is not possible on our planet. Beorn, a human who is able to morph into other animals at an instant, is a good example of this kind of fiction. The dragon, Smaug, is the main adversary of the fourteen main characters. Dragons have been the evil focal point of stories for years. Although most of the characters' species a... Free Essays on Hobbit Free Essays on Hobbit The Hobbit The Hobbit by J.R.R.

Basic Parts of the Brain and Their Responsibilities

Basic Parts of the Brain and Their Responsibilities The scarecrow needed it, Einstein had an excellent one, and it can store a whole lot of information. What is it you say? Why, the brain of course.  The brain is the control center of the body. Think of a telephone operator who answers incoming calls and directs them to where they need to go. Similarly, your brain acts as an operator by sending messages to and receiving messages from all over the body. The brain processes the information it receives and ensures that  messages are directed to their proper destinations. Neurons The brain is composed of specialized cells called neurons. These cells  are the basic unit of the nervous system. Neurons send and receive messages through electrical impulses and chemical messages. Chemical messages are known as neurotransmitters and they can either inhibit cell activity or cause cells to become excitable.   Brain Divisions The brain is one of the largest and most important organs of the human body. Weighing in at about three pounds, this organ is covered by a three-layered protective membrane called the meninges. The brain  has a wide range of responsibilities. From coordinating our movement to managing our emotions, this organ does it all.  The brain is composed of three main divisions: the forebrain, brainstem, and hindbrain. Forebrain The forebrain is the most complex of the three parts. It gives us the ability to feel, learn, and remember. It consists of two parts: the telencephalon (contains the cerebral cortex and corpus callosum) and the diencephalon (contains the thalamus and hypothalamus). The cerebral cortex allows us to understand the mounds of information we receive from all around us. The left and right regions of the cerebral cortex are separated by a thick band of tissue called the corpus callosum. The thalamus acts as a telephone line of sorts, allowing information to get through to the cerebral cortex. It is also a component of the limbic system,  which  connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and  spinal cord.  The hypothalamus is important for regulating hormones, hunger, thirst, and arousal. Brainstem The brainstem consists of the midbrain and the hindbrain. Just as the name suggests, the brainstem resembles the stem of a branch. The midbrain is the upper part of the branch that is connected to the forebrain. This region of the brain sends and receives information. Data from our senses, such as the eyes and ears, are sent to this area and then directed to the forebrain. Hindbrain The hindbrain makes up the lower portion of the brainstem and consists of three units. The medulla oblongata controls involuntary functions such as digestion and breathing. The second unit of the hindbrain, the pons, also assists in controlling these functions. The third unit, the cerebellum, is responsible for the coordination of movement. Those of you who are blessed with great hand-eye coordination have your cerebellum to thank. Brain Disorders As you can imagine, all of us desire a brain that is healthy and functions properly. Unfortunately, there are some who suffer from neurological disorders of the brain. A few of these disorders include: Alzheimers disease, epilepsy, sleep disorders,  and Parkinsons disease.
