Quizplus · Accepted Answer

Myelin is a substance that forms around nerve fibers and helps to speed up the transmission of nerve impulses. This means that the development of myelin is important for the development of fine motor skills such as finger snapping. However, simple motor behaviors such as nodding the head do not require the same level of muscular control, so they can develop earlier in infancy.
