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.

Understanding the Context

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. In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension.

FLEXION meaning: 1. the act of bending an arm, leg, etc. or of tightening a muscle: 2. the act of bending an arm…. Learn more.

Final Thoughts

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. At Flexion, we build software that’s easy and affordable to change, helping you lead and respond to changes in a complex, unpredictable world. We create systems with options at every level, allowing you to iterate rapidly to align policy, adopt new tech, and continuously improve. Flexion is defined as a movement that decreases the angle between two bones or body parts meeting at a joint. This action brings the articulating bones closer together, representing a bending motion.

What is flexion and extension movement? Flexion is a movement that causes the angle between two bones of a joint to decrease, such as when a person bends their elbow joint.
