Flexor Muscles

A flexor muscle is one which decreases the angle between two bones, as in bending the arm at the elbow; raising the leg toward the stomach as in kicking a football; or bringing the lower leg up toward the thigh. Another flexor muscle will bring the thumb across the palm of the hand. A "dorsiflexior" is used for the movement at the ankle joint in trying to bring the foot in proximity to the leg.
