What are the three compartments of the lower 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.

What are the compartments of the legs?
Compartments of the leg:
- Anterior compartment (blue): Tibialis anterior, extensor muscles of the foot, and fibularis (peroneus) tertius muscles.
- Lateral compartment (green): Fibularis (peroneus) longus and fibularis (peroneus) brevis muscles.

What are the 3 muscle compartments in the leg?
The thigh has three muscle compartments:
- Anterior compartment (pink) – Sartorius and quadriceps muscles (rectus femoris, vastus lateralis, vastus intermedius, vastus medialis).
- Medial compartment (green) – Pectineus, obturator externus, gracilis, and adductor muscles (longus, brevis, magnus, minimus).

What muscles are used for dorsiflexion?
The tibialis anterior muscle, found in the anterior compartment of the leg, is the primary muscle that facilitates dorsiflexion of the ankle joint.
What is in each compartment of the leg?
Anterior compartment (blue): Tibialis anterior, extensor muscles of the foot, and fibularis (peroneus) tertius muscles. The anterior tibial artery and deep fibular (peroneal) nerve supply the anterior compartment. Lateral compartment (green): Fibularis (peroneus) longus and fibularis (peroneus) brevis muscles.
What are the four compartments of the lower leg quizlet?
Which of the following is the basic action of the posterior compartment of the thigh?
Posterior thigh muscles (hamstrings)
| Definition and function | The hamstrings are the muscles of the posterior thigh that are primarily in charge of knee flexion and thigh extension |
|---|---|
| Primary functions | Flexion of leg, extension of thigh, stabilization of knee and hip joints |
Where is the syndesmosis?
ankle joint
The syndesmosis is a fibrous joint held together by ligaments. It’s located near the ankle joint, between the tibia, or shinbone, and the distal fibula, or outside leg bone. That’s why it’s also called the distal tibiofibular syndesmosis.
What are the three compartments of the thigh?
What nerve supplies posterior compartment of thigh?
Posterior compartment (blue) – Biceps femoris, semimembranous, and semitendinous muscles. The sciatic nerve innervates the posterior compartment. The deep femoral artery supplies the posterior compartment.
What are the 6 main ligaments of the ankle joint?
The main stabilizing ligaments are deltoid ligament medially, anterior, posterior talofibular and calcaneofibular ligament laterally.
- Medial Ligament.
- Lateral Ligament.
- Plantarflexion.
- Dorsiflexion.
What is the ATFL?
The ATFL is a ligament that is part of the ankle capsule (intra-capsular) (fig 1). The ligament is approximately 2mm thick, 7mm wide, and 25mm long. It arises from the anterior tip of the lateral malleolus and travels antero-medially, to insert on the lateral side of the talar neck.
What is between the tibia and fibula?
The interosseous ligament lies between the tibia and fibula. (Interosseous means between bones.) The interosseus ligament is a long sheet of connective tissue that connects the entire length of the tibia and fibula, from the knee to the ankle.
