The sartorius muscle is a thin, long, superficial muscle in the anterior compartment of the thigh. It runs down the length of the thigh, runs over 2 joints—hip and knee joints and is the longest muscle in the human body. An exceptional length of this muscle often exceeds 50cm.
29 Ιουλ 2020 · The Sartorius muscle is the long muscle that is attached to the lower portion of the outer hip toward the top. It extends downward from the hip, crosses atop the inner thigh and connects with the inner knee. This muscle is commonly injured when running, from a direct hit such as in football, or jumping around.
The sartorius, the longest muscle in the body, crosses the hip and the knee joints. It originates at the anterior superior iliac spine and inserts superficially on the pes anserinus as a broad fascial insertion. It functions to flex the hip, and secondarily to adduct the thigh and externally rotate the leg.
3 Νοε 2023 · The sartorius muscle crosses both the hip and knee joints, producing movements on both of them. At the hip joint it is capable of flexion, external rotation and abduction of the leg. The contraction of sartorius can also cause flexion of the knee joint and inward, or medial, rotation of the tibia against the femur.
Pes Anserine bursitis, also known as intertendinous bursa, is an inflammatory condition of bursa of the conjoined insertion of the sartorius, gracilis and semitendinosus. We can locate this at the proximal medial aspect of the Knee, two inches below the medial knee joint line between the pes anserinus tendons.
The knee flexors include the set of hamstrings, gracilis, sartorius, gastrocnemius, plantaris, and popliteus. Most of these knee flexors also internally or externally rotate the knee. The hamstring muscles are the primary knee flexors. They play a key role in everyday movements, eg running, walking. Bending of the knee is known as flexion.
Origin: The upper lateral facet on the ischial tuberosity. Insertion: A horizontal groove on the posteromedial surface of the medial tibial condyle. Nerve: Tibial division of the sciatic nerve (L5, S1 and 2) Artery: Branches from the internal iliac, popliteal, and profunda femoris arteries. Function:
