Answer: As a collective functional unit, the muscles in the anterior compartment of the leg are responsible for DORSIFLEXION AND INVERSION OF THE FOOT AT THE ANKLE JOINT

Explanation:

There are four muscles in the anterior compartment of the leg.

1. Tibialis anterior

2. Extensor digitorum longus

3. Extensor hallucis longus and

4. Fibularis tertius.

Based on their origins and insertions on the foot, contraction of these four muscles will lead to a shortening of the muscle’s body and cause the dorsum of the foot to be pulled towards the leg. This movement is known as dorsiflexion. Also, certain muscles from this group assist in the inversion of the foot.

The muscles in this compartment are innervated by the deep fibular nerve (L4-S1), and blood is supplied via the anterior tibial artery.

The Great Barrier Reef, located off of Australia’s eastern coast, is the largest coral reef ecosystem in the world. The reef covers an area over 300,000 square kilometers and includes a wide range of ocean depth, and it contains such biodiversity as to make it one of the most complex ecosystems on Earth. Much like any other ecosystem on Earth, the Great Barrier Reef relies on biotic and abiotic components to keep it functional and stable.
