Compartments of the leg and their content - anterior, lateral, superficial posterior, deep posterior

Leg compartments refer to specific sections of the leg, each enclosed by fascia, a dense connective tissue. These compartments contain muscles, nerves, and blood vessels. Understanding the compartments of the leg is important in fields like anatomy, medicine, and sports science, especially concerning compartment syndrome, a condition where increased pressure within a compartment can impede blood flow and damage tissue. The leg is divided into four main compartments: 1. **Anterior Compartment**: **Muscles**: Tibialis anterior, extensor hallucis longus, extensor digitorum longus, fibularis tertius **Nerve**: Deep fibular (peroneal) nerve **Artery**: Anterior tibial artery **Functions**: Dorsiflexion of the foot, extension of the toes 2. **Lateral Compartment**: **Muscles**: Fibularis longus, fibularis brevis **Nerve**: Superficial fibular (peroneal) nerve **Artery**: Fibular artery (perforating branches) **Functions**: Eversion of the foot 3. **Superficial Posterior Compartment**: **Muscles**: Gastrocnemius, soleus, plantaris **Nerve**: Tibial nerve **Artery**: Posterior tibial artery (perforating branches) **Functions**: Plantarflexion of the foot 4. **Deep Posterior Compartment**: **Muscles**: Tibialis posterior, flexor digitorum longus, flexor hallucis longus, popliteus **Nerve**: Tibial nerve **Artery**: Posterior tibial artery, fibular artery **Functions**: Plantarflexion and inversion of the foot, flexion of the toes Each compartment is enclosed by a fascial layer that helps maintain the structure and function of the muscles, nerves, and vessels within it.
