What structures are in the popliteal space?
These include the two terminal branches of the sciatic nerve, the popliteal vessels and short saphenous vein. Several muscles of the thigh and leg form the boundaries of the popliteal fossa. They include the semimembranosus, semitendinosus, biceps femoris, gastrocnemius and popliteus muscles.
What are the contents of the popliteal fossa?
The popliteal fossa has 4 main borders made from posterior muscles and tendons of the leg and thigh; Superomedial border = Tendons of semimembranosus with the semitendinosus superficial to it. Superolateral border = Tendon of biceps femoris. Inferomedial border = medial head of gastrocnemius.
What is the common term for the popliteal region?
The popliteal fossa (sometimes referred to colloquially as the knee pit, or poplit) is a shallow depression located at the back of the knee joint. The bones of the popliteal fossa are the femur and the tibia.
What is the meaning of popliteal space?
The Popliteal Fossa is a diamond-shaped space behind the knee joint. It is formed between the muscles in the posterior compartments of the thigh and leg. This anatomical landmark is the major route by which structures pass between the thigh and leg.
What is the function of the popliteal?
The popliteus muscle assists in knee flexion and its function is decided according to the position of the lower extremity, i.e. weight-bearing or non weight-bearing, as it is a primary internal rotator of the tibia in a non weight-bearing position.
What is area below knee called?
The popliteal fossa (sometimes referred to as hough, or kneepit in analogy to the cubital fossa) is a shallow depression located at the back of the knee joint. The bones of the popliteal fossa are the femur and the tibia.
What is behind your knee called?
The shallow depression formed at the back of the knee is called the popliteal fossa; it is formed at the junction of the femur and tibia.
What is popliteal surface of femur?
The popliteal surface is located on the caudodistal part of body of femur: it is smooth triangular area bounded laterally by the continuation of the medial and lateral lips of facies aspera, and distally by the intercondylar line.
Where is your popliteus?
knee
The popliteus (pronounced pop-lit-ee-us) is a thin, flat, triangular muscle in the posterior compartment of the distal leg region. It helps to form the lower part of the popliteal fossa, or the pit of the knee.
Why popliteus is called the key to knee?
Popliteus is often referred to as the “Key” to unlocking the knee since it begins knee flexion by laterally rotating the femur on the tibia.
What is the function of popliteal?
Function. The popliteus muscle assists in knee flexion and its function is decided according to the position of the lower extremity, i.e. weight-bearing or non weight-bearing, as it is a primary internal rotator of the tibia in a non weight-bearing position.
What is the area between the knee and ankle called?
leg
The leg from the knee to the ankle is called the crus or cnemis /ˈniːmɪs/. The calf is the back portion, and the tibia or shinbone together with the smaller fibula make up the front of the lower leg.
What is the back of the knee area called?
What is the popliteus?
Despite its small size, the popliteus is a major stabilizer of the knee. The popliteus is involved in both the closed chain phase and open-chain phase of the gait cycle. During the closed chain phase, which is when the foot is in contact with the ground, the muscle externally rotates the femur on the tibia.
Where is the popliteus?
The Popliteus is a small, thin, flat, triangular shaped musclotendinous complex of the lower leg with the popliteus muscle and the popliteofibular ligament and constitutes a part of the posterolateral corner of the knee.. It is a deep muscle of the knee joint, forming the floor of the popliteus fossa.
What does popliteus mean?
Definition of popliteal : of or relating to the back part of the leg behind the knee joint.
Where does the popliteus attach?
The popliteus muscle originates from the lateral surface of the lateral condyle of the femur by a rounded tendon. Its fibers pass downward and medially. It inserts onto the posterior surface of tibia, above the soleal line.
