How is motor development best described?

• A. The ability to coordinate large movements
• B. The growth of muscular coordination
• C. The improvement of fine motor skills only
• D. The psychological aspects of movement

Answer: (B)

Motor development is best described as the growth of muscular coordination because it encompasses the overall progression and refinement of physical skills related to movement. This includes both gross motor skills, which involve large muscle groups and coordinated movements such as running, jumping, and throwing, as well as fine motor skills, which require more precise movements, such as writing or buttoning a shirt.

The term "growth" in this context refers to the physical changes and maturation processes that contribute to an individual's ability to perform a wide range of movements efficiently and effectively. Muscular coordination is a crucial aspect because it involves not just muscle strength but also timing, balance, and the ability to integrate sensory information to execute movements.

While coordinating large movements and fine motor skills are components of motor development, they are not comprehensive enough to define the concept on their own. Likewise, the psychological aspects of movement can influence how motor skills are developed and performed but do not define motor development itself. Thus, the most accurate description centers on the overall enhancement and coordination of muscular control.
