Fine motor skills are the collective skills and activities that involve using the hands and fingers . That is, fine motor skills are those skills that require the small muscles of the hand to work together to perform precise and refined movements. The process begins in infancy when baby first bats at a toy, progressing to grasping, releasing, and transferring objects between their hands, then progressing to using fingers to manipulate and explore things, stack blocks, self-feed and dress, and during the early childhood years, use ‘school tools’ such as scissors, markers, crayons, pencils, and glue.
Gross motor skills involve the large muscles of the body that enable such functions as walking, kicking, sitting upright, lifting, maintaining balance, coordination, jumping and throwing a ball. A person’s gross motor skills depend on both muscle tone and strength to maintain upper body support, for example, will affect his ability to write and sit erect in a chair.
