Recommended: Question about peripheral nervous system
The nervous system is primarily separated into the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain, its nerve cranial and the spinal cord. The peripheral nervous system is made up of the spinal nerves that extent from the spinal cord and the autonomous nervous system separated from the sympathetic and parasympathetic nervous systems. Next would be the structure of the brain. The brain is designed by two different cells. The neurons and glial cells, otherwise known as neuroglia or glia. The neurons objective is to send and bring in nerve impulses and signals. Glial cells are non-neuronal cells that give support and nutritional value, maintains homeostasis, creates myelin and facilitates
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from the CNS, to transmit information to your limbs and organs, for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical signals to transmit information.
The nerves are made of neurons which are the cells that receive, process and transmit messages from one neuron to another. The nervous system is separated into two main parts; the central nervous system and the peripheral nervous system. The central nervous system is made up of the brain and the spinal cord. The second part of the nervous system is the peripheral nervous system which allows the central nervous system to communicate with the muscles, joints, glands and organs.
The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells that sends information to the brain to be analyzed.
The brain consists of both neurons and glia cells. The neurons, which are cells housed in a cell body called a Soma, have branches which extend from them, referred to as dendrites. From these dendrites extend axons which send and receive impulses, ending at junction points called synapses. It is at these synapse points that the transfer of information takes place.
A bunch of nerves put together is called the Nervous system. The Nervous system helps with body coordination and provides sensory information about external problems. The nervous system controls the brain, spinal cord, sense organs, etc. Without our nervous system, we would not be able to function, since
“Quietly, unobtrusively and extremely fitfully, something in my mind began to assert itself, to question things, and to refuse to be brainwashed…” The main character, Tambudzai, in the novel Nervous Conditions by Tsitsi Dangarembga, is determined to get a white education without losing her native tongue and ways. However this proves to be more difficult that she would expect and seeds that are planted in her mind by the whites begin to take shape, and greatly affect her existence. I will begin by giving an overview of the story leading up to the point where Tambu heads off to begin her education at the missionary school. Next I show how Tambu has already been brainwashed into believing that the white’s educational system is better than her own. Following I will discuss the influences that Tambu had to overcome in order to refuse to be brainwashed further. Finally I will give exam to the insight that Tambu’s story offers on the situation of a person in her position.
The bridging of native traditions with modern imperial ways has a direct effect on the minds of Zimbabwean girls and women. Dangarembga drew inspiration for her title from the quote “the condition of the nation is a nervous one”, from Frantz Franon’s book Wretched of the Earth. The reader sees this idea of nervousness displayed within the female main characters of this novel. “ Its bad enough, when a country gets colonised but when the people do as well! That’s the end, really, that’s the end. (Nervous Conditions,150). This quote stated by Nyasha addresses how colonialism and imperialism are not just cultural, political and economical, but psychological as well. It infiltrates the minds of the citizens and their very cultural existence. The women in this novel are faced with the choice of embracing the British ways or running back to their Shona roots. No matter the choice they make, the Imperial control of the British Empire over Zimbabwe affects the minds of these women. The title of Dangarembga's novel, Nervous Conditions, alludes to the influence imperialism has on the minds of Tambu, Nyasha and Maiguru as they struggle to re-define themselves in a white man’s world.
that she has a firm sense of her identity and to mix that with a
The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included with in it.
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The neurons established within the various sections of the nervous system, is structured with three main parts: a dendrite which is a cluster of branches that operates by receiving information from the receptor and neurons and transferring nerve impulses to the cell body; furthermore, a cell body is composed of a nucleus, that works to provide energy and nutrients for the neuron; lastly is an axon, electrically conducted by the myelin sheath, the axon is a pathway nerve impulses pass through from the cell body. In addition, this is the process in which nerve impulses travel by to be able to access the rest of the system (Core Science, 2010). The correct function of the nervous system is vital to the daily survival of an individual, as it obtains a significant role in the control and co-ordination of the human body. Furthermore, if a situation occurs where the nervous system dysfunctions or develops a disease (such as multiple sclerosis), it would in that case threaten the current status of one’s health and cause havoc in the system.
Nervous system is one of the major organ systems that is responsible for the coordination of biological activities inside the body through cells called neurons. It is composed of the brain and spinal cord which are surrounded by protective layers of bone and membrane tissues called meninges. There are two major divisions in the nervous system; first one is the central nervous system (CNS) and the other being the peripheral nervous system (PNS). The CNS is composed of the brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons. The nervous system applies control using nerves; almost as if sending a message by a telephone. The nervous system is fast due to its electrical nature. The nerve cells in this system are connected with each other in a complex manner where the neural pathways would be possible. Neural
The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
