The 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.

The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let 's take a look at the central nervous system.

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.

Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.

Neurons are information- processing units in the central nervous system that receive and transmit information. It is made up of an axon, dendrites and a cell body. The nucleus and cytoplasm are contained in the cell body. The axon starts from the cell body, dividing into smaller branches and then ends at the nerve terminals. The dendrites also branch from the cell body, receiving information from the other neurons. Axons from other neurons forms

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

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.

Nerve cells are made up of things called neurons, the cell body of the neuron has a long tinny axon that is covered by something called a myelin sheath, the axons are what pass the information from neuron to neuron and other cells in the body. The axons have a cover to protect them called myelin, this is what allows the brain and spinal cord to communicate with each other (Lindhom, 2014).

Neurons are made up of four parts which are the dendrites, the soma, the axon and the myelin. Dendrites are the branches of the neuron which receive messages and are attached to the soma. The soma contains the nucleus and is mainly responsible for keeping the cell alive and running. Axon is the message carrier of the neuron and it does so as a fiber attached to soma. Lastly, the myelin is a fatty substance made by glial cells that serves as a protecting sheath around the axons. It also speeds up the neural message traveling down the axon.

Neurons are what make up the nervous system. The nervous system is very complex for all the activities that this system performs. It main function is to communicate. It sends nerve impulses to the muscles (effectors), the muscles receive stimuli and tuned electromechanical signals that are sent to the

The main function of the nervous system is to send and receive information, in a message like form, and then respond to these messages. These messages get passed through the body using neurons, which are nerve cells. But neurons are not like regular cells, they cannot be repaired if they are damaged because of injury and/or disease. Neurons are wired together through our whole body, and act like a communication system. The brain can send messages to the neurons using the spinal cord, and nerves.

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 CNS is composed of the brain and the spinal cord. This system is responsible for the sensory information and responding accordingly. The spinal cord sends signals between the brain and the rest of the body and controls simple musculoskeletal reflexes. This isn’t using input from the brain. The brain is responsible for most sensory information and coordinating body function, both consciously and unconsciously. Also one portion of the CNS we may forget at times is the retina. The retina is formed as an out pocketing of the diencephalon during development. This is known as the optic vesicle.

As such, neurons form the basic and functional units of the nervous system. The big picture behind the work of the nervous system and its neurons is that a change in the environment (Stimulus) causes us to produce some response to that change. Just as electricity travels in a wire, rapid impulses travel through neurons to relay messages. These are because of the charged particles, known as ions, that create either resting or action potentials in our bodies, using the sodium-potassium pump. The stimulus, however, is first detected by a receptor, such as our eyes or ears and is then coordinated with an effector, such as muscle contraction, that produces an effect, in response to the stimulus. Impulses caused by stimuli and picked up by receptors travel through nerves that consist of one type of neuron, called sensory neurons until reaching the central nerves system, which is essentially the brain and spinal cord. In other cases, nerves may contain motor neurons, that send signals to muscles and glands in our bodies. There may also be a combination of motor neurons and sensory neurons in other nerves. This eventually ends in our bodies responding to the initial change. The anatomy of the neuron in the simplest form consists of a cell body, nucleus, dendrites, axon, myelin sheaths, axon branches and axon bulbs. The cell body of the neuron

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.
