Today we will discuss something special. The entire Neuron team decided that this 10th video will be dedicated to explaining what a nerve cell... ...or a neuron is! We all know that nerve cells transmit electrical impulses within our body. Our brain consists of about 86 billion nerve cells that work together to receive and transmit signals between the brain and other parts of the body. But... how does it actually work? First, let's start with the structure. First, is the portion known as the axon. This section is in charge of transmitting electrical signals from one nerve cell to the next, which will finish at the final destination, usually an organ or muscle. In addition, we also have dendrites. Dendrites are structures responsible for receiving signals from other nerve cells such as from organs or the brain. Electrical signals will travel from the dendrites through the cell body. The cell body contains the nucleus. While the nucleus is an organelle that contains genetic material and regulates the growth and development of the nerve cell. In addition, there are many nerve cells that possess a structure called the myelin sheath which affects how fast the electrical signals travel and pass through the nerve cells. Did you know? That signals in our body can travel as fast as 120 meters per second in nerve cells that have myelin sheaths? Okay. So we have a better picture of the structure of nerve cells. But what about the transmission of signals? For instance, how does our brain tell our thumb to move? This occurs through a complex mechanism. Our brain starts something called an action potential which passes along the nerve cells to reach the thumb and move it. Our nervous system contains nerves and nerves are a bundle of nerve cells or neurons. Between one nerve cell to the next is a gap called a synapse. The travelling action potential or electricity will be received by the dendrite in the first nerve cell and transmitted through its body until the axon. In the first few neurons or nerve cells there are chemical messengers called neurotransmitters. These play a role in the conduction of these signals from one nerve cell to the next. Neurotransmitters are released into the synapse and generate an action potential in the second nerve cell. Here, the electricity will be passed to the next nerve. And so on until the last nerve cell conveys the electricity to the target muscle in the thumb. As a result, our thumb is able to move. This process inspired us to name ourselves Neuron. It's our hope that we can receive information, process it and convey it to all of you for the purpose of education. We would like to thank all of you who have always supported us during this time and to also wish a warm welcome to all new viewers who have just joined us on this journey.
