What is the function of a flexor muscle?

  1. Straightens the fingers

  2. Bends the wrist

  3. Extends the wrist

  4. Contracts the shoulder

The correct answer is: Bends the wrist

The function of a flexor muscle primarily involves bending or flexing a body part. In the context of the wrist, flexor muscles are responsible for decreasing the angle between the forearm and the hand, thereby bending the wrist. These muscles allow for actions such as gripping and holding objects, which are crucial in nail technician work for manipulating tools and performing nail services. Flexor muscles are located primarily on the anterior (front) side of the forearm and work in opposition to extensor muscles, which are responsible for straightening or extending the wrist and fingers. Understanding the role of flexor muscles is essential for nail technicians, as it aids in ergonomic practices and prevents strain during services.
