Which of the following involves the use of small muscles, such as fingers?

The choice related to the use of small muscles, such as fingers, is accurate because fine motor skills specifically refer to the coordination and control of small muscle movements. These skills are crucial for tasks that require precision and dexterity, such as writing, buttoning clothes, or using small tools. Fine motor skills develop through activities that involve refined movements and are essential for many daily functions, particularly in children as they grow and learn new activities.

In contrast, gross motor skills pertain to larger muscle movements that involve the whole body or large segments of it, such as running, jumping, or throwing a ball. This distinction emphasizes the size and function of the muscles involved in each type of skill.

Barriers to learning and feedback do not fit this context, as they relate to obstacles in the educational process and the information provided to improve performance, respectively. Therefore, the focus on small muscle activity confirms that fine motor skills are the correct answer, highlighting their importance in development and daily activities.
