What is the function of extensor muscles?

The function of extensor muscles is primarily to straighten the wrist, hand, and fingers. These muscles are responsible for extending joints, which means they help move body parts away from each other, particularly in the context of the limbs. For instance, when you open your hand or stretch your fingers out, it is the extensor muscles that are actively engaged in that movement.

Understanding the role of extensor muscles is crucial for nail technicians, as a thorough knowledge of the anatomy and function of muscles in the hands allows for better practice in services that require detailed movements and positioning of the hands. This knowledge can enhance the technician's ability to perform tasks like manicures and pedicures with greater precision, while also being aware of the muscle groups involved in hand and finger movements.
