The Human Central Nervous System

Encephalitis is a neurological disorder that results in the inflammation of the brain and sometimes the meninges. It is usually due to a viral infection. Most often arboviruses cause encephalitis, by transference via mosquitos to humans and animals. When bitten by an infected mosquito the virus moves from the mosquito into the person’s blood, it then reaches the brain and spinal cord, it multiplies within the central nervous system thus inflaming and damaging nerve cells, this interferes with signals from the brain to the rest of the body. The herpes simplex virus type one can commonly cause encephalitis. HIV has also been noted as an increasing cause of encephalitis. Viral infections like: mumps, chicken pox and measles can also cause encephalitis, but rarely.

Encephalitis literally means an inflammation of the brain, but it usually refers to brain inflammation caused by a virus. It may also be called “acute viral encephalitis or aseptic encephalitis';. Encephalitis is an infectious disease of the Central Nervous System characterized by pathologic changes in both the gray and white matter of the spinal cord and brain. It may be due to specific disease entity such as rabies or an arthropod-borne virus (arbovirus), or it may occur as a sequela of influenza, measles, German measles, chicken pox, herpes virus infection, small pox, vaccinia, or other diseases. The specific viruses involved may vary. Exposure can also occur through insect bites, food or drink, or skin

Every behavior begins with biology. Our behaviors, as well as our thoughts and feelings, are produced by the actions of our brains, nerves, muscles, and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being, including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it works.

The central nervous system and the peripheral nervous system is the 2 main systems. The central nervous system is made up of the spinal cord and brain which is in the dorsal body cavity. It is the integrating and control center of the nervous system. Also the CNS helps with sensory input, dictates motor outputs based on reflexes and lastly past and current experiences.

Encephalitis which is an inflammation of the brain, caused by a virus. The post infectious encephalitis occurs as a complication of another infection, such as chicken pox, influenza or measles, or after a smallpox vaccination . The neurological disturbances causes seizers, personality change, irritability, lethargy, paralysis, weakness and coma may also occur. The inflammation involves the spinal cord and the brain.

crucial to understand the anatomy of a normal brain. The central nervous system consists of

The central nervous system (CNS) is the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The two main organs of the CNS are the brain and spinal cord. The brain processes

The central nervous system (CNS) is part of the human body which includes the brain and spinal cord (Lewis, Heitkemper, Dirksen, & Bucher, 2014). The cells of the nervous system are known as neurons, which is protected and nourished by neuroglia (Lewis et al., 2014). The spinal cord includes ascending and descending tracts which controls sensory and muscle movements (Lewis et al., 2015)

The action that is required for standing up is for the muscle to contract in the lower portion of the body from the gluteus maximum to the Gastrocnemius muscle.

The central nervous system is mainly the brain and spinal cord. These two have a very specific protective covering to build up by other soft tissues. The brain is dividing into forebrain, mid brain, and the hind brain. Most of the functional mapping for the muscular movements and the sensory approach, as well as the executive functions, is delivering throughout the fore brain into the discrete regions. The mid brain creates a part of the brainstem, which is basic keeping that person alive. The hind brain is involved in the formation of the head which is necessary to maintaining balance of the body. The spinal cord is a barred shaped of the nerve that connects to the brain. The spinal cord nerves transmit information from the body organs and

The central nervous system consist of the brain and spinal cord. The brain plays a crucial role and is a significant function of the nervous system by using information from our senses to tell us what is going on around us, and how we should respond. Although, the brain has an essential purpose it is my belief that the spinal cord is the most important. It’s the center of many spinal reflexes, and can participate in reflex actions without checking with the brain. The spinal cord communicates with the brain it sends messages if damaged it can affect other body functions such as breathing, hormone release, body temperature, bowel and bladder, movement of food through the stomach and intestines. Messages, touch, transmitting pain movement, joints,

One of the most important parts of your body is your central nervous system (CNS). It includes your spinal cord and your brain, and it is run by cells called neurons. These neurons, with the help of synapses, send electrical signals throughout the body.

The central nervous system is one of the most important systems in the human body, and at its core is the neuron. Neurons are cells that facilitate the transmission of electrical signals throughout the body. They allow the nervous system to act as a communication network that runs throughout the entire body. Without neurons, the brain could not tell the rest of the body what to do. Neurons come in various shapes and sizes; however, they all share the same basic structure. Additionally, there are several different types of neurons that perform a variety of functions.

Anatomically, the central nervous system (CNS) is made up of the brain and the spinal cord (Kalat, 2013). These two things represent our body’s communication center. In aspects to just the brain, it is made up of 3 various parts, the forebrain, the midbrain and the hindbrain. Each part of the brain has a specific function. The forebrain consists of thalamus, hypothalamus, and the cerebrum. The midbrain, other wise known as the mesencephalon, is made up of tectum and tegamentum. Lastly, the hindbrain consists of the cerebellum, pons, and the medulla.

Encephalitis is a condition caused by viruses which cause the brain to become inflamed. There are two types of encephalitis one is called primary because the viruses affect the brain itself. Secondary is the viruses travel from some other part of the body that has been affect to the brain. When the virus reaches the brain it begins to multiply causing inflammation. The brain’s white matter can be destroyed. This destruction causes cell death, hemorrhage and edema. The edema begins to compress the blood vessels this causes intracranial pressure (Mayo Clinic, 2011).
