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.

The latest research into development and learning of babies and young children shows that early stimulation are vital to the healthy development of brain. Babies are born with 100 billion neuron cells and they need to connect together in order to function. Many of these connections are made as result of what a baby senses and experiences. Stimulation, sufficient sleep and healthy diet makes a difference in allowing connections to be made. Development of brain begins well before birth. Neurons (cells in the brain which transmit electrical impulses to other cells) are formed between the 10th and 20th week of pregnancy. These cells are critical as they will later join together to allow the brain to function properly. Electrical pulses pass between cells via dendrites and axons which causes the connection between the neuron cells. The dendrites and axons of the neurons develop and begin the process of joining up in the final two months of pregnancy. Those that have not made enough strong connections are killed off and this is one reason why some children are

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

* Second, research has shown that damage to incoming sensory pathways or the destruction of brain tissue can lead to neural reorganization.

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

The main components of the synapses are as follows: The Axon terminal, found at the end of the Axon, passes neurotransmitters to other neurons via synaptic transmission. Synaptic Vesicles contain neurotransmitters within the Axon. Neurotransmitters themselves are chemical messengers that travel through the neurons and activate receptors on the receiving cell. The neurotransmitters are diffused through the synaptic cleft—a region between the two neurons and gap the neurotransmitter needs to cross to make it to the receiving cell. Said receiving cell is what receives the neurotransmitters and starts the process over again. The receptors on the cell are structures that receive the neurotransmitters and

Most people usually think of the brain or heart being the most important part of our body. While they are indeed important, they would be entirely useless if certain substances called neurotransmitters didn’t exist. Neurotransmitters are substances in our body that carry signals from one nerve cell to another. Without these neurotransmitters in our body, we wouldn’t receive crucial signals such as telling our heart to beat. Six of the most common neurotransmitters in our body are dopamine, serotonin, endorphins, norepinephrine, acetylcholine, and gamma-aminobutyric acid (GABA).

Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g., skeletal muscle; myocardium, pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e., becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions across that membrane, making cells more likely to become depolarized, if the neurotransmitter happens to be excitatory, or less likely if it is inhibitory.

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.

Advancement made in regard to cognitive neuroscience has enabled a better understanding of the cognitive processes in infants. Studies have indicated that cognitive development in infants starts before they are born. In the eighth week of pregnancy, fetuses have the ability to hear. They become accustomed to their

As soon as the electrical signal reaches the end of the axon, mechanism of chemical alteration initiates. First, calcium ion spurt into the axon terminal, leading to the release of neurotransmitters “molecules released neurons which carries information to the adjacent cell”. Next, inside the axon terminal, neurotransmitter molecules are stored inside a membrane sac called vesicle. Finally, the neurotransmitter molecule is then discharged in synapse space to be delivered to post synaptic neuron.

During the first two years the brain is the most flexible and prepared to learn. At this time everything is new. Everything an infant does build brain connections. According to EDUCARER.org "Touch, talking and things an infant sees and smells all build connections if done with continuity in a loving, consistent, and

You live and you learn, from the moment that we breathe our first breath, we are assimilating and are acquiring information. Life changing and profound learning experiences happen before we can even speak, as children our learning process is grandiose. Harvard University published a series of summaries on Child development. One of these articles mentions that “The basic architecture of the brain is constructed through an ongoing process that begins before birth and continues into adulthood.” ("InBrief: The Science of Early Childhood Development," n.d.).
