Action of this muscle

Extension of digits 2-5 and eversion of the foot

Origin of this muscle

Anterior surface of the fibula and adjacent anterior interosseus membrane

Insert of this muscle

Dorsal surface of the distal phalanx of digit 1

Action of this muscle

Extension of digit 1. supports dorsiflexion and inversion of the foot
