Flexor muscle

A flexor muscle is a skeletal muscle whose contraction bends a joint, decreasing the angle between components of a limb, such as bending the knee or elbow.

The type of muscle that has the opposite effect is the extensor muscle, which opens a joint, increasing the angle between limb components.

In humans, some muscles include 'flexor' in their name, some include;

• Flexor carpi radialis
• Flexor carpi ulnaris
• Flexor digitorum profundus muscle
