Question

Quizplus · Accepted Answer

Myelination refers to the process of the myelin sheath forming around nerve fibers. As children develop, their nerve fibers become increasingly myelinated, which allows for more efficient transmission of signals throughout the brain and body. This can improve fine motor skills, such as the ability to hold and manipulate a crayon, making it more likely that a child like Isaac will learn to write legibly.
