Quizplus · Accepted Answer

Myelination, the process of forming a fatty layer around nerve fibers, is crucial for the development of motor skills such as walking and balancing. The corpus callosum, a band of nerve fibers that connects the two hemispheres of the brain, plays a role in coordinating movements between the left and right sides of the body. The cerebellum, located at the back of the brain, is responsible for controlling balance and coordination. As myelination increases in these areas, Troy's motor skills will improve, allowing him to catch up with his older brother.
