# Flexion – A decrease in the angle between two bones, or midline of the body

### (Pronounced flek-shn)

While flexing his bicep, the direction (flexion) his hand moved was towards his shoulder, decreasing the angle of his elbow joint.

Starting with the anatomical positions, we can now find all the places on a human body where flexion occurs i.e. where there is a decrease in the angle between two bones.
