Flexion refers to a movement that decreases the angle between two body parts. Flexion at the elbow is decreasing the angle between the ulna and the humerus. When the knee flexes, the ankle moves closer to the buttock, and the angle between the femur and tibia gets smaller.
Flexion is a bending movement that decreases the angle between a segment and its proximal segment. [9] . For example, bending the elbow, or clenching a hand into a fist, are examples of flexion.
For the vertebral column, flexion (anterior flexion) is an anterior (forward) bending of the neck or body, while extension involves a posterior-directed motion, such as straightening from a flexed position or bending backward.
Flexion is the medical term for bending an arm or leg. Techically speaking, it's a physical position that decreases the angle between the bones of the limb at a joint.
