Central Nervous System

The nervous system in general is quite a complex and sophisticated system which is responsible for regulating and coordinating the body’s activities. The central nervous system consists of the brain and spinal cord, mainly responsible for gathering information and responds to any changes within environment.

Common complications of meningitis include hearing loss, seizures, pneumonia, and more serious complications involve the cranial nerves, which would include facial weakness and blindness. It is recommended that patients with meningitis have a 30-degree head elevation of their beds. CT scan is a good way to assess the patient’s symptoms to rule out skull fractures or congenital abnormalities. Most of the complications contribute to parenchymal damage and increased intracranial pressure. As these patient’s bodies try to fight the infection, seizures can be a result. Fluid cannot be drained properly which increase sodium levels in the brain. Seizures can be managed with anticonvulsant and benzodiazepine medications as well as proper fluid management through intravenous management. Hearing loss results in the damage of some of the nerve endings in the cochlea of the ear. The first 48 hours are critical in detecting and reversing hearing loss in patients. Another complication is facial weakness and blindness, which is the outcome of inflammation of the meninges, which can affect the cranial nerves. These nerves supply the head and neck with their blood supply so when that is affected, the resulting nerve is

In the organization of the Human Nervous System it is divided into sections such as the sensory system, which gathers and process information from the surrounding environment: motor systems which responds from environment by sending signals and information to facilitate movement behavioral responses and the associational system which is a meditator from most multifaceted and least problematic brain functions. Within these different functions of the nervous system it is divided into two components where these functions can happen the central nervous system that comprises of brain and spinal cord and peripheral nervous system that embodies nerves and ganglia.

The Central Nervous System is the control center of the nervous system. Containing the brain and the spinal cord, the central nervous system interprets signals that are created by neurons through sensory inputs and prescribes them into motor outputs. Multiple

Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.

The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and

Central nervous system is located in the cerebral cortex or the brain (Marieb, Mitchell, 2011). The brain gets information it processes and then gives out an appropriate response from past experiences (Marieb, Mitchell, 2011). According to the central nervous system lecture, the brain can be compared to a computer system, although the brain is much more complex. The central nervous system is aided by the peripheral nervous systems, whose main job is to send information from the external environment picked up the by sensory receptors to the cns (Marieb, Mitchell,

Meningitis is associated several unpleasant symptom such as fever, vomiting, headache, limb pain, and neck stiffness(Refernce). The severity of symptom varies according to the type of pathogen , duration of illness and the age of child( feign1992 ). .According to the recent evidence based reports, Suspected bacterial meningitis is a medical emergency, and immediate diagnostic steps must be taken to establish the specific cause so that appropriate antimicrobial therapy can be initiated. The mortality rate of untreated bacterial meningitis approaches 100 percent and, even with optimal therapy, morbidity and mortality may occur. Neurologic sequelae are common among survivors.meningities is considered as medical emergency required Now, of course, the admission to hospital can be unpleasant for the child and the use of antibiotics itself might cause some adverse effect. However, the illness syndrome and complications results in much more suffering over a longer duration than does the

The peripheral nervous systemcontrols all voluntary amd involutary muscles and glands. Peripheral nervous system contains all your nerves amd nerve bundles excluding the brain and spinal cord. The Central spinal cord. The CNS receives sensory infpormation from the nervous system and controls the body's responses. The diffrence between peripheral and central nervous system are th CNS, collections of neurons are called nuclei. In the PNS, collection of neurons are called ganglia. another diffrence would be the CNS, collections of axons are called tracts. In the PNS, collections of axons are called nerves.

The nervous system helps maintain homeostasis by controlling and regulating the other parts of the body. A deviation from a normal set point act as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain. For example, “breathing is involuntary, the nervous system ensures that the body is getting much needed oxygen through breathing the appropriate amount of oxygen.” This shows that the nervous system plays a role in making sure that the breathing patterns of a human stays constant in order to maintain homeostasis. This system is the control center of the human body. The Control center sets the range of value to be maintained and is made up of the brain, spinal cord and nerves. The nervous system is important to the human body because its an organ system in charge of sending messages to and from the brain and spinal cord to and from all parts of the body. What helps send these messages are nerves, one or more bundles of fibers forming part of a system that conveys impulses of sensation, motion, etc, between the brain or spinal cord and other parts of the body. Nerves act as highways to carry signals between the brain and spinal cord and the rest of the body. The Central Nervous system is the complex of nerve tissues that controls the activities of the body, it consists of two parts: the brain and the spinal cord. The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel enables us to have memories and feelings- all the things that makes us human. Three main parts of the brain is the forebrain, midbrain, hindbrain. The Forebrain consists of the cerebrum, thalamus, and hypothalamus, The Midbrain consists of the tectum and tegmentum, The Hindbrain is made of the cerebrum, pons and medulla, brainstem.

In the central nervous system, neurons, microglia, astrocytes and oligodendrocytes secrete exosomes into the extracellular environment (Glebov 2015), raising the possibility that communication mediated via extracellular vesicles is a common mechanism in the CNS. It has been reported that exosomes are involved in the normal development and physiology of the nervous system. One study demonstrated that mature hippocampal and cortical neurons released exosomes in response to calcium and glutamatergic synaptic activity, which suggests a role in normal physiology (Lachenal 2011).

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

The central nervous system and the peripheral nervous system work together to collect information from within the body and from the environment outside it. The systems process all the collected information and send instructions to the body; to obtain an appropriate response. Once the data arrives, the brain will sort and file it before sending out any commands on what to do. The central system is the main command center of the body that contains the brain as well as the spinal cord. The peripheral nervous system contains a network of nerves that connect the rest of the body to the central nervous system.

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 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.
