Flexion is a movement that decreases the angle between two body parts.
In simpler terms, flexion is a bending movement that reduces the angle between bones or body parts at a joint. This often brings the bones closer together. It's a fundamental type of movement occurring throughout the body.
Here are some key characteristics of flexion:
- Decreases the Angle: This is the defining characteristic. The angle at the joint becomes smaller.
- Bending Movement: Flexion is typically associated with a bending motion.
Examples of Flexion in the Body
To illustrate flexion, consider these common examples:
- Elbow Flexion: Bending your arm at the elbow, bringing your hand closer to your shoulder. The angle between your ulna/radius (forearm bones) and humerus (upper arm bone) decreases.
- Knee Flexion: Bending your knee, moving your heel towards your buttock. The angle between your femur (thigh bone) and tibia/fibula (lower leg bones) decreases.
- Neck Flexion: Bending your head forward, bringing your chin towards your chest.
- Hip Flexion: Raising your knee towards your chest. The angle between your torso and femur decreases.
- Wrist Flexion: Bending your hand forward at the wrist.
Importance of Flexion
Flexion is crucial for various daily activities, including:
- Walking
- Running
- Lifting
- Sitting
- Grasping objects
Flexibility and range of motion in flexion are essential for overall physical function and preventing injuries.
In summary, flexion is a vital movement that decreases the angle between body parts, enabling a wide range of everyday activities.
