👉 Myelination is a process in which nerve cells become more organized and functionally integrated into their axon, or long, straight line of nerve fibers. This occurs as a result of genetic factors that determine whether an organism has a specific type of neural tube formation, called myeloid tissue, or if it lacks this feature. This allows for the development of specialized neurons that work together to transmit information from one part of the body to another, allowing for communication between different parts of the body.
