Neurons: Part of the Nervous System

2.The basic cell that makes up the nervous system and which receives and sends messages within that system is called a neuron.

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

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 cell body comprises of the nucleus and other organelles (Ward, 2010). The nucleus contains the genetic code, and this is involved with protein synthesis (He, 2013). The dendrites receive information from other neurons which are located in a close proximity (Kalat, 1995). The terminal of an axon compresses into a disc-shaped structure (Gross, 2010). This is where chemical signals also known as a neurotransmitter permit interaction amongst neurons, by means of a minute gap named a synapse (Martin, Carlson & Buskit, 2013). Both neurons which form the synapse are referred to as a presynaptic synapse (prior to the synapse) and postsynaptic (after the synapse), reflecting the direction of information flow (from axon to dendrite), (He, 2013).

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

|  A neuron is known as an excitable cell that can process and transmit information through electrical and chemical signals. Neurons are the core components of the nervous system, which includes the brain, spinal cord and nervous system.

The structure of a neuron consist of four main components dendrites, cell body also known as soma, synapse and axon. Dendrites collect signals coming in from other cells. The soma is responsible for assimilating signals coming in from the dendrites in order to create a signal traveling unidirectional through the axon. The axon stems from the soma, which

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 are nerve cells that transmit nerve signals to and from the brain at up to 200 mph. The neuron consists of a cell body (or soma) with branching dendrites(signal receivers) and a projection called

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.

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.

Reaction time is the time between the presentation of a stimulus and the initiation of the muscular response to that stimulus ( the free dictionary [26/07/14].The purpose of this test was to identify what happens to reaction times as different independent variables are applied. The nervous system helps all parts of the body to communicate with each other, it is responsible for making sure all of the body’s parts coordinate properly. The nervous system is the centre of all the body’s activity (better health channel [26/07/14]). The brain and spinal cord make up the central nervous system and all the other nerves in the body part of the peripheral nervous system. Inside nerves lie neurons, neurons are found in the brain, spinal cord and the peripheral nerves (PubMed Health [26/07/14]). They are also known as nerve cells. These neurons have the same structure as plant and animal cells (differencebetween.net [27/07/14]). Neurons are made up of a cell body, dendrites, a nucleus, an axon and a myelin sheath (the nervous system [27/07/14]). The myelin sheath surrounds the nerve fibre of axon and protects the body from the electrical charge that nerves have (GCSE Bite size [27/07/14]). There are two types of neurons: sensory neurons and motor neurons. Sensory neurons send signals to the brain and spinal
