What muscles are in the lateral compartment?
Lateral compartment (green): Fibularis (peroneus) longus and fibularis (peroneus) brevis muscles. The superficial fibular (peroneal) nerve and branches from the anterior tibial artery supply these muscles. Superficial posterior compartment (purple): Gastrocnemius, soleus, and plantaris muscles.
What is in the lateral compartment of the leg?
Containing the fibularis longus muscle (FLM) and fibularis brevis muscle (FBM), common fibular and superficial fibular nerves, and branches of the anterior tibial and fibular arteries, the lateral leg compartment is one of the four compartments of the leg.
What is the most lateral of the foot muscles?
The lateral leg muscles that insert on the foot are the fibularis longus and fibularis brevis. These two muscles perform eversion of the foot and are innervated by the superficial fibular nerve. The intrinsic muscles of the foot can be further broken down into the dorsal aspect and the plantar aspect.
What are the compartment muscles?
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 lateral compartment?
The lateral compartment of the leg, also known as the peroneal compartment, is one of the four compartments in the leg between the knee and foot. Muscles within this compartment primarily produce ankle and foot eversion.
What muscle inserts into lateral malleolus?
Peroneus longus
Fibularis longus | |
---|---|
The mucous sheaths of the tendons around the right ankle. Lateral aspect. (tendon-sheath of the peroneus longus labeled at bottom center.) | |
Details | |
Origin | Proximal part of lateral surface of shaft of fibula |
Insertion | First metatarsal, medial cuneiform |
What is the plantar side of the foot?
The plantar fascia is the thick connective tissue (aponeurosis) which supports the arch on the bottom (plantar side) of the foot. It runs from the tuberosity of the calcaneus (heel bone) forward to the heads of the metatarsal bones (the bone between each toe and the bones of the mid-foot).
What is the lateral side of the foot?
The cuboid bone is a square-shaped bone on the lateral aspect of the foot. The main joint formed with the cuboid is the calcaneocuboid joint, where the distal aspect of the calcaneus articulates with the cuboid.
What is an intrinsic muscle?
Definition. A group of muscles located within or situated deeper in a structure, in contrast to extrinsic muscles located rather superficially. Supplement. Based on the above definition, the intrinsic muscles refer to the muscles closest to the axial and appendicular skeleton.
How many compartments are in the foot?
The foot is divided into 4 large compartments (interosseous, medial, lateral, central) each including muscles, nerves and arteries, although it is debated whether there are actually 9 compartments, however, it is more practical to think of the foot in 4 compartments.
Which of the following are actions of the muscles of the lateral leg compartment?
Muscles
Muscle | Proximal Attachment | Main Action |
---|---|---|
Fibularis longus | Head and superior two thirds of lateral surface of fibula | Everts foot and weakly plantarflexes ankle |
Fibularis brevis | Inferior two thirds of lateral surface of fibula |
What is medial and lateral compartment?
The medial compartment is the side of your knee closest to the other knee. The lateral compartment is on the other side of your knee.
