What is "flexor"?

The flexor refers to a group of muscles responsible for bending or flexing various joints in the body. These muscles work in opposition to extensor muscles, which are responsible for extending or straightening joints. Flexor muscles can be found throughout the body, such as the flexor muscles in the forearm that bend the fingers or the flexor muscles in the thigh that help in bending the knee joint. The flexor muscles play a crucial role in movements such as grasping, pulling, and bending, providing strength and control for daily activities and specialized tasks. Their coordinated action allows for dexterity and precision in hand and limb movements, contributing to overall mobility and function.
