Final answer:
Discrete motor skills have a specified beginning and end of movement, unlike continuous motor skills.
Step-by-step explanation:
Motor skills that have a specified beginning and end of movement are known as discrete motor skills. These are actions that have a clear and distinct start and finish, such as throwing a ball, buttoning a shirt, or kicking a soccer ball. Unlike continuous motor skills (e.g., running or swimming), where movement has no clear beginning or end, discrete motor skills involve a specific and identifiable action.
