Extensor Hallucis Longus lives on the front (anterior) part of the lower leg, crossing the ankle and extending all the way to the end of the big toe.
Extensor: extends
Hallucis: referring to the big toe (aka 'toe #1')
Longus: there is most likely a shorter version of this muscle (aka 'brevis')
Extensor Hallucis Longus Muscle Attachments:
Origin: middle 1/3 of the anterior fibula and the middle 1/3 of the interosseous membrane
Insertion: distal phalanx of the big toe
(aka to the tip of the last bone)
Extensor Hallucis Longus Muscle Actions:
a) dorsiflexion of the foot at the ankle joint
b) extension of the big toe
a) dorsiflexion of the foot at the ankle joint
aka toes pointing up to the sky (& heel down towards ground)
b) big toe extension
its pretty much impossible for me to isolate just the big toe doing extension (without the other toes tagging along - a bit grainy - but can you see the tendon of extensor hallucis longus popping out?)
