* White matter is one of the two components of the central nervous system, and it consists of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another as well as in between the cerebrum and lower brain centers. Grey matter contains neural cell bodies. Unlike white matter, it is mostly made up of myelinated axon tracts. Tracts are bundles of fibers that connect to different parts of the CNS. Roots receive information sent by neurons. Spinal nerves refer to a mixture of spinal nerves, which carry

6.The fatty substances produced by certain glial cells that coat the axons of neurons to insulate, protect, and speed up the neural impulse is the myelin.

The neuron is very important to the nervous system and also to the human body as well. The neuron is a very strong cell, but it still can have it’s fair share of malfunctions. There are also 3 types of neurons in the human body. These different neurons are all important because they all do important things to help the human body. Neurons are important cells to the body and can do many important things to help the nervous system and the human body.

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 are:1. highly specialized cells that produce myelin.2. highly specialized cells that receive and transmit information from one area of the body to another.3. found only in the spinal cord and bone marrow.4. found in primates and humans, but not in other animals.

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

Everything we do is a product of neural communication, whether that be reacting to senses or feeling emotions, it is all due to us having neural communication through millions of neurons passing small electrical signals throughout the body through such pathways as the central nervous system and the peripheral nervous system and passing information to and from the brain. These ‘’neurons’’ are made up of Dendrites which are connected to a cell body, or also known as the soma, these are tree-like feathery filament ‘’message receivers’’ that collect these messages from other neurons it is connected to, neurons are connected through a dendrite to axon terminal connections and pass these ‘’messages’’ through the body as action potentials.

The axons are slender processes of uniform diameter arising from the hillock. There is usually only one unbranched axon per neuron.

Neurons communicate with one another along a synapse. Neurons are excitable cells that are activated via electrical or chemical signals. Nerve cells are an integral part of the nervous system. Neurons are made up of three distinct parts. The three integral parts of the neuron are the cell body, the dendrites, and the axon. The cell body is the middle portion of the neuron and contains the nucleus. It also contains the organelles such as the endoplasmic reticulum and the mitochondria.

Neurons have a part called the dendrites and this is where the neuron fires a correct impulse to another neuron through the axon. Axon is a long projection that connects nerve cells.

Neurons (also known as neurons, nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons.

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

Human brain consists of billions of cells interconnected together, with each performing its separate functions. It consists of two explicit categories of nerves: neurons and glia cells. Neuron is a single nerve cell in the entire nervous system; which is electrically excitable cell that carries information after being processed via chemical or electrical signals. One of its key characteristics is that it does not undergo cell division. In addition, it maintains a voltage gradient for all the neurons across its membranes. Glia cells, on the other hand, its functionality is to maintain homeostasis.

Nerve cells generate electrical signals to transmit information. Neurons are not necessarily intrinsically great electrical conductors, however, they have evolved specialized mechanisms for propagating signals based on the flow of ions across their membranes.
