#Compartments of leg innervation skin#

This joint allows for dorsiflexion and planterflexion of the ankle. The septa are formed from the fascia which is made up of a strong type of connective tissue. just two, fibularis longus and fibularis brevis, innervated by. of calcaneum Action Powerful plantar flexor of ankle Nerve Supply Tibial nerve ( S1. 1 Each compartment contains connective tissue, nerves and blood vessels. How many muscles are in the lateral leg compartment Name them and their innervation. Muscles, arteries and nerves of posterior compartment of leg. The common peroneal nerve is a major terminal branch of the sciatic nerve. Damage to the common peroneal nerve causes a lack of sensation in the leg and foot, as well as foot drop, a condition where the foot cannot be plantarflexed.

Talocrural (Ankle) Joint : Uniaxial, modified hinge, synovial joint located between the talus, medial malleolus of the tibia and the lateral malleolus of the fibula. The lower leg is divided into four compartments by the interosseous membrane of the leg, the anterior intermuscular septum, the transverse intermuscular septum and the posterior intermuscular septum. It provides innervation to the skin of the lateral and leg, the top of the foot, and to many leg muscles. There is little movement at the inferior tibiofibular joint but it allows for a small spread of the bones at the ankle joint during dorsiflexion. Both are syndesmosis joints and are supported by the anterior and posterior tibiofibular ligaments and the inferior transverse and interosseous ligaments.

Tibiofibular Joint: Superior and inferior tibiofibular joints are where the tibia and the fibula articulate. Now, proximal to the popliteal fossa, lets show how the sciatic nerve unbundles to innervate the anterior, lateral, and posterior leg compartments. superficial fibular n.: muscles of the lateral compartment of the leg (fibularis longus and brevis mm.) deep fibular n.: muscles of the anterior compartment of.
