Ever wonder how the human body works, well there are two main systems to help the human body move , the nervous system is comprised of two subdivisions. The central nervous system is the coordinating system for the body. The peripheral nervous system is a very complex network of nerves that extend across the whole body. Both are vital to the human body and without either life would not exist. The nervous system works together with other systems to send signals to the brain. The central nervous is made up of the brain and the spinal cord.
The nervous system is responsible for all the process the make human life possible. It lets us think, dream, and have a lifetime of memories. It also handles our most basic, involuntary actions and reactions …show more content…

It is roughly the size of a large grapefruit and kind of looks like a cauliflower. The human brain is probably the most complex organ in the body. It has 100 billion nerve cells, or neurons, and trillions of support cells called glia. If you could remove all 100 billion nerve cells and arrange them in a straight line, they would stretch for a distance of about 600 miles (1000 kilometers.) Of course, you would not be able to see this line since nerve cells are only visible under a microscope. Many scientist think that if you tried to count all of the neurons in the human brain, it would take you more than three thousand …show more content…

These include the nerves that leaves the brain and the spinal cord and extend to all parts of the body. Part of the job of the peripheral nervous system is to gather information from sensory receptors and relay, or send out, this information to the CNS. The messages are transmitted in the form of electrical signals, or nerve impulses. The central nervous system then interprets the messages it receives and sends out the appropriate responses to the body’s glands, muscles, and

In the Crash Course video, I learned about the different structures of the brain. Franz Joseph Gall, the first phrenologist, introduced a new theory in the early 1800’s. Gall believed that a person’s personality was linked to the ridges and bumps on the skull. However, scientists today understand that the brain contains different parts that are responsible for specific functions. One system of the brain is commonly referred to as the “old brain”.

According to Martini, F., Tallitsch, R., Nath, J., (2018), the ANS functions outside of our conscious awareness and makes routine adjustments in our body’s systems (Martini, Tallitsch, & Nath, 2018, p. 450). The autonomic nervous system helps maintain the homeostasis of our bodies by regulating body temperature and coordinating cardiovascular, repertory, digestive, excretory, and reproductive functions. Efferent axons innervate the visceral organs and the efferent nerve fibers and ganglia of the ANS organize in two systems or divisions. The sympathetic division and the parasympathetic division. The sympathetic division is most active during times of stress, exertion, or emergency, also known as “flight or fight”.

Caution: Central Control Problem The brain controls everything the body does. The spinal cord carries messages between the body and the brain. Together, they make up the central nervous system (CNS). Some prescription drugs slow down, or depress, the CNS.

In this passage, Jane is delivering a letter to from Thornfield to Hay for Mrs. Fairfax and is describing her surroundings. She had been working as a governess for Adele and was tired of being staying inside the house all the time. Brontë incorporates both long sentences and imagery to provide vivid descriptions and develop Jane’s environment. The setting Brontë describes provides the reader with a visualization and reflection of what is occurring in the novel. With this detailed depiction, Brontë establishes the setting before latter events such as when Jane meets Rochester for the first time; Brontë also accordingly adjusts the description of the setting and breaks the serene landscape previously painted.

The cerebellum and brain stem constitute the hind brain. The tectum and the cerebral peduncles form the mid-brain. The forebrain is made of the diencephalon, cerebrum, meninges and cerebro-spinal fluid. A brain tumour or intracranial neoplasm is an abnormal growth of cells within the brain. The tumors are generally grouped on the basis of their grades.

When the skater does tricks their brain sends electrical signals to the nerves of what the trick is and what movements the skater should make. The nervous then tells the muscles how to move. When the muscles move the bones moves with it. The last essential body system pair that works together is the digestive system and the circulatory system.

Frankly, all processes in the human body are orchestrated by the brain, which represents one of the most sophisticated structures in the universe. Over the course of human evolution, the brain of homo sapiens has developed into the phenomenon that makes us who we are – the humans. The uniqueness and complexity of the human brain continues to be a subject of ongoing research and speculation; however, there are still numerous questions and hypotheses behind the function of the brain. The brain is an intricate system, an organ, where each structure serves a specific function, which supports every aspect of human life. Every structure, no matter how small it is, carries out specific tasks that allow the brain, along with the entire body, to

First, let 's talk about the brainstem, limbic system, and cerebral cortex. The brainstem is in charge of all the functions our body needs to stay alive. It also lets the brain know what is happening with the body. Next is the limbic system, that links together a bunch of brain structures that control our emotional responses.

1. INTRODUCTION 1.1 Brain Asymmetry In general, any biological system shows some degree of asymmetry in their organization. From the highly intelligent system such as human to the lower animals, normal variation and specialization result in formation of asymmetries in both structure as well as function. In some mammalian system including human, the two brain hemisphere differ in their anatomy and function.

The muscular system is very important for everyday life. Without it we wouldn't be able to carry out everyday tasks such as writing this paper or tying our shoes or anything. This system also helps us distribute wastes when our body doesn’t need them anymore, which is important because if the wastes build up the toxins will enter your system the wrong way and it will harm you eventuly. This system interacts with the many other systems but the main two are the nervous system and the digestive system. The nervous system is what controls the brain and the brain tells us to move certain parts of our bodies without us knowing it, this is how our involuntary muscles move.

Nervous Conditions is a partially autobiographical novel by Zimbabwean author Tsitsi Dangarembga that takes place in Rhodesia in the late 1960s and early 1970s. It focuses on the themes of race, class, and gender through the eyes of Tambu, the young female protagonist. The title references Jean Paul Sartre 's introduction to Frantz Fanon 's 1963 book The Wretched of the Earth, in which he writes, "the status of 'native ' is a nervous condition introduced and maintained by the settler among the colonized people with their consent. " Dangarembga expands Fanon 's exploration of African people oppressed by a colonial regime by incorporating the gender-specific role of black women, who are arguably doubly oppressed. The women in Dangarembga 's novel grapple with "nervous conditions" borne from years of colonialism as well as the continued oppression under the Shona power system.

The first part of the Nervous System is the Central Nervous System. “Protected within the skull, the brain is composed of mostly of the cerebrum, cerebellum, and brainstem.” (“Anatomy of the Brain, mayfieldclinic.com”) The cerebrum is the biggest part in the human brain, and is divided into lobes including the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. Each lobe has its own tasks.

The human body is an amazing thing made up of many different parts. These parts are cells, tissues, organs, and organ systems. For starters, one type of cell makes up one type of tissue. Next, two or more types of tissues make an organ. Then, a few organs working together make an organ system.
