Understanding The Structure And Function Of A Neuron

3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon.

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

As well as these there are also the axon of the cell which is covered in myelin sheaths which carried information away from the cell body and hands the action potentials, these are small short bursts of change in the electrical charge of the axon membrane through openings of ion channels, off to the following neurons dendrites through terminal buttons at the end of the axons. Whenever an action potential is passed through these terminal buttons it releases a chemicals that pass on the action potential on to the next neuron through the terminal button and dendrite connection. The chemicals that are

To send a message, a neuron will send a ripple of electrical energy down its axon. This ripple is called "action potential." The way it works is by changing the chemical makeup of the axon's negatively charged interior. Positively charged sodium ions move into the cell and negatively charged potassium ions move out, then the ions move to their original positions. This produces a wave of positively charged

2.Dendrite are the receptive region of the neuron. They conduct electrical impulses toward the cell body.

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).

First and foremost, dendrites are truly interesting cells within the host body. A neuron is a tiny, microscopic cell. Often, neurons are confused with nerves, but both are different things. Neurons are not nerves, although both are related! Nerves are made from a large bundle of axons and dendrites and are macroscopic or visible to the naked eye (Chabner 346; Coon and Mitterer

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

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.

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

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.

Neurons. Neurons, otherwise called nerve cells, impart inside the body by transmitting electrochemical signs. Neurons look truly not the same as different cells in the body because of the numerous long cell forms that stretch out from their focal cell body. The cell body is the generally round piece of a neuron that contains the core, mitochondria, and the majority of the cell organelles. Little tree-like structures called dendrites reach out from the phone body to get jolts from nature, different neurons, or tactile receptor cells. Long transmitting methods called axons stretch out from the phone body to send flags ahead to different neurons or effector cells in the

Information conveyed by the synapses on the dendrites is processed and projected from the axon. The axon is extraordinary, it is specialized for signal conduction to the next neuron. Axons vary in length, the ones in your brain are relatively short in comparison to the axons that run from your spinal cord down to your foot (about a meter long).
