The lower leg subdivides into four compartments which are the anterior, lateral, superficial posterior and deep posterior compartments.
How many compartments does leg have?
As we said before, the leg is divided into three muscular compartments, however this can sometimes be classified as four muscle groups. The anterior and lateral compartments occupy only a small portion of the muscular volume of the leg.
What is anterior compartment of the leg?
The anterior compartment of the leg is one of the four compartments in the leg between the knee and foot. Muscles within this compartment primarily produce ankle dorsiflexion and toe extension.
What is anatomical compartment?
Anatomy. Compartments are groupings of muscles, nerves, and blood vessels in your arms and legs. Covering these tissues is a tough membrane called a fascia. The role of the fascia is to keep the tissues in place, and, therefore, the fascia does not stretch or expand easily.
What is the fascia in the leg?
The deep fascia of the leg is continuous above with the fascia lata (deep fascia of the thigh), and is attached around the knee to the patella, the patellar ligament, the tuberosity and condyles of the tibia, and the head of the fibula….

What are the compartment of leg?
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. Each compartment contains connective tissue, nerves and blood vessels.

What is muscle compartment?
A well-defined region that contains a group of muscles within a particular segment of the body. For example, the lower leg contains four muscle compartments: the anterior compartment, lateral compartment, posterior deep leg compartment, and posterior superficial compartment. See also compartment syndrome.
What do you mean by compartment?
1 : a separate division or section. 2 : one of the parts into which an enclosed space is divided. compartment.
What is a compartment of the leg?
The fascial compartments of the leg are the four fascial compartments that separate and contain the muscles of the lower leg (from the knee to the ankle). The compartments are divided by septa formed from the fascia. The compartments usually have nerve and blood supplies separate from their neighbours.
What is a lower leg compartment?
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. Each compartment contains connective tissue, nerves and blood vessels.
What muscle groups are in the lower leg?
The lower leg muscle s are composed of three major muscle groups: the gastrocnemius, soleus and tibialis anterior. The gastrocnemius is the largest section of the lower legs, comprised of the medial and lateral heads. Commonly called the ‘calves’, it’s the most obvious and most worked out muscles in the lower legs.
What muscles are in your lower leg?
The lower leg lies between the knee and the ankle. There are many muscles located in the lower leg, but there are three that are particularly well known: the gastrocnemius and the soleus, which are the most powerful muscles in the lower leg, and the anterior tibialis.
What is compartment leg syndrome?
Compartment syndrome of the lower leg is a condition where the pressure increases within a non-extensible space within the limb. This compromises the circulation and function of the tissues within that space as it compresses neural tissue, blood vessels and muscle.
