FLEXOR POLLICIS BREVIS

KNOW YOUR MUSCLES:

The flexor pollicis brevis muscle is a short muscle which runs from the wrist to the thumb and when it contracts it bends the thumb towards the palm. A flexor muscle is one that 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.
