When an electrical signal reaches the end of an axon, it causes the release of chemicals called neurotransmitters. These neurotransmitters then bind to receptors on the surface of other cells, causing them to either fire an electrical signal or not. This process is how neurons communicate with each other and with other cells in the body.<\/p>\n<p>Lymphs are a type of white blood cell that helps to fight infection. They are produced in the bone marrow and circulate through the body in the lymphatic system. The lymphatic system is a network of vessels that helps to remove waste products and toxins from the body.<\/p>\n<p>Nephrons are the functional units of the kidney. They are responsible for filtering the blood and producing urine. Urine is a waste product that contains water, salts, and other substances that the body does not need.<\/p>\n<p>Nerves are bundles of axons that transmit information from the brain and spinal cord to other parts of the body. They are made up of three types of cells: neurons, glial cells, and Schwann cells. Neurons are the cells that transmit information, glial cells provide support and protection for neurons, and Schwann cells wrap around axons to form myelin sheaths, which insulate axons and speed up the transmission of information.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on
