I have chosen to investigate this topic as my gran is currently in hospital suffering from this.
The central nervous system (CNS) consists of the brain and the spinal cord. The brain is the most complex of all organs and has a central role which is to control all of the bodily functions, such as awareness, movement, sensations, thoughts, speech and memory. Sensory neurons also known as are nerve cells receive information as tiny electrical signals. There are three different type of neurons that all have a different function. Sensory neurons carry messages (signals) to the spinal cord and then on to the brain, relay neurons carry messages from one part of the CNS to the other whereas the motor neurons carry messages from the CNS to effectors. For example if a person accidently touches something very hot the skin receptors would very quickly send nerve impulses to the spinal cord which would then be processed on to the brain and the

Many things can cause a SAH such as a bleeding disorder, hypertension (high blood pressure), use of blood thinners or the most common a ruptured anuerysm. An anuerysm is when an artery in the brain becomes enlarged due to weakness in the arterial wall. When this happens to a person the blood from the anuerysm can leak into the cerebrospinal fluid (CSF) into the subarachnoid space around the brain and the blood can then irritate, damage or destroy nearby brain cells. This causes many problems with bodily functions and mental skills such as speech, balance and coordination, focussing on tasks, vision problems, memory, hearing and lots more. If a brain anuerysm is caught before rupturing it can be treated. Brain anuerysms that are small (less than 10mm) have a low chance of rupturing therefore if caught early on a doctor would avoid surgery and try to monitor the patient making sure they are not at risk of the anuerysm growing which would then be
The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.
1. Neurons is a basic building block of the nervous system. The sensory nerves carry the message from body tissues to the brain and spinal chord to be processed. The motor neurons are then used to send instructions to the body tissue from the brain and spinal cord. Dendrites, which are connected to the body cell (soma) receive information and pass it through the axon. Myelin sheath covers the axon and helps speed the process. When triggered by a signals from our senses or other neurons, the neuron fires an impulse called the action potential. The resting potential is the neuron’s visual charge of positive
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.
Continuing on we as a class learned about the spinal cord, which is a column of nerves lining our back, as well as the central nervous system, which is the human body’s main processing unit. Chapter two focuses primarily on these two aspects of the body. The central nervous system is the brain and spinal cord, the brain, hindbrain, and midbrain are in charge of the senses. Hearing and sight for example are dealt with in the forebrain. The nervous system includes many different working pieces that control the body. Such as Dendrites; these are the hairs on the neurons. Ions have both negative and positive neurons which each has three, included with the soma in the cell body. Axon is the long tube of it, and the terminal button is the end of the tube.
The central nervous system is made up of the brain and spinal cord. The brain is connected to the spinal cord. The brain helps interpret information received from the spinal cord. Through the spinal cord signals are sent to the rest of body and back to the brain. Nerve cells (neurons) are found in the nervous system and they help communicate with other cells through electrical signals. Some of the nerve cells are coated with a myelin sheath. Myelinated neurons allow electrical signals to travel at a faster speed. When the myelinated part of the nerve cell is destroyed, Multiple Sclerosis (MS) can be the one to blame.
The Central nervous systems include the brain and spinal cord which transfers voluntary nerve impulse to skeletal muscles, skin, muscles, and glands.
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 spinal cord and the brain are the main parts of the central nervous system. The spinal cord is aligned from the base of the brain, through the back, which allows the body to move and have sensation. The spinal cord contains dendrites, supporting cells, and axons, long nerve fibers, that attach to the brain to carry out messages. The axons have sheaths of insulation called myelin and the dendrites receive signals from other dendrites. Dendrites actually make
The CNS contains the brain and spinal cord. Its main functions include: processing, integrating, and coordinating sensory information and motor instructions. The sensory data conducts information that is being processed from internal and external conditions the body is experiencing. Motor commands regulate and control peripheral organs (skeletal muscles). The brain functions under memory, emotions, learning, and intelligence. The PNS consist of the neural tissue found outside of the CNS. It functions in sending data to the CNS which motor commands are than carried out to the peripheral tissues/systems. Multiple nerve fibers send sensory data and motor commands in the PNS. The nerves that assist with transmitting data include the cranial nerves and spinal nerve. However, the PNS can be divided into afferent (to bring in) and efferent (to bring out) divisions of transferring data. The afferent division functions in bringing in sensory data to the CNS. Sensory structures are receptors that detect internal/external environmental change and adjusting accordingly. The efferent division functions in carrying out motor commands from the CNS to glands, muscles, and adipose tissue. The efferent division contains somatic
Whereas the spinal cord (often referred to as the brainstem) is the pathways that enables nerve impulses to reach their various destinations in the body. The central nervous system main function is to receive information from the different parts of the body, in which must be analysed and stored in order for it to send out instructions based on those pieces of information. The central nervous system’s main function is to coordinate the numerous organs and muscles required to perform the individual’s desired action(s) (Walker, 2005).
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 two components of the central nervous system (CNS) are the brain and the spinal cord. Communication between the brain and the spinal cord happens through motor neurons, which are nerve cells that enable motor movement. Each motor neuron is made up of a cell body, which holds all the cell components, dendrites which send information it receives to the cell body, and an axon which sends nerve impulses to the muscle (Porth & Matfin, 2009). As electrical impulses are sent through the motor neuron, it stimulates the muscle fibers in the body to move. This is the process in which motor function happens. Therefore, the basic abilities to breathe, speak, swallow, walk and button a shirt are
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.
