Anterior Leg Compartment [Part 2] | Digital Extensors (EDL & EHL)

The video tutorial provides an in-depth look at the extensor digitorum longus (EDL) and extensor hallucis longus (EHL) muscles. It covers their anatomy, including origins, insertions, actions, and innervation. The EDL is responsible for extending digits 2-5 and assists in dorsiflexion and subtalar eversion. The EHL extends the great toe and aids in dorsiflexion. Both muscles are innervated by the deep fibular nerve. The tutorial concludes with a brief introduction to toe yoga, which will be covered in subsequent videos.

What is the primary action of the Extensor Digitorum Longus?

• Plantarflexion of the ankle

• Inversion of the foot

• Extension of digits 2 through 5

• Flexion of the big toe

Which nerve innervates the Extensor Digitorum Longus?

• Superficial fibular nerve

• Sural nerve

• Tibial nerve

• Deep fibular nerve

Where does the Extensor Hallucis Longus originate?

• Lateral surface of the tibia

• Middle third of the medial surface of the fibula

• Posterior surface of the tibia

• Anterior surface of the fibula

What is the main action of the Extensor Hallucis Longus?

• Flexion of the big toe

• Inversion of the foot

• Plantarflexion of the ankle

• Extension of the big toe

Which artery primarily supplies blood to the Extensor Hallucis Longus?

• Fibular artery

• Anterior tibial artery

• Posterior tibial artery

• Lateral plantar artery

What is the antagonist muscle to the Extensor Hallucis Longus?

• Flexor digitorum longus

• Flexor hallucis longus

• Tibialis anterior

• Peroneus longus

What is the purpose of toe yoga as mentioned in the video?

• To strengthen the calf muscles

• To increase flexibility in the knee

• To improve balance

• To mobilize tissues in the foot and ankle
