A muscle that produces dorsiflexion; the muscle group responsible for bending the foot upward, primarily the tibialis anterior muscle in the lower leg.
From 'dorsi-' (back), 'flex' (bend), and Latin '-or' (agent suffix). Names the anatomical structure that performs the action of dorsiflexion.
Your dorsiflexor muscles are small but mighty—they work constantly to keep your toes from dragging when you walk, and when they fatigue, that's why you start tripping!
