The biceps femoris (/ ˈ b aɪ s ɛ p s ˈ f ɛ m ər ɪ s /) is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this characterization, as it only causes knee flexion (but not hip extension) [1] and is activated by a separate ...
The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
The mean age for ACS in men is 30 years while the mean age is 44 years for women. [19] Acute compartment syndrome may occur more often in individuals less than 35 years old due to increased muscle mass within the compartments . [9] The anterior compartment of the leg is the most common site for ACS. [9] [63]
Gaenslen test - This pain provocation test applies torsion to the joint. With one hip flexed onto the abdomen, the other leg is allowed to dangle off the edge of the table. Pressure should then be directed downward on the leg in order to achieve hip extension and stress the sacroiliac joint. [1] [2]
The short head of the biceps also has 3 important arms in the posterolateral corner. The capsular arm attaches to the posterolateral capsule as well as the fibula, just lateral to the styloid and provides a strong attachment to the capsule, lateral gastrocnemius tendon, and capsuloosseus layer of the IT band. The fabellofibular ligament is ...
biceps femoris muscle, which consists of a short head and a long head. semitendinosus muscle; semimembranosus muscle; These muscles (or their tendons) apart from the short head of the biceps femoris, are commonly known as the hamstrings. The depression at the back of the knee, or kneepit is the popliteal fossa, colloquially called the ham. The ...

The biceps brachii primarily serves to supinate the forearm at the elbow joint. [1] The muscle belly is composed of two heads. The short head is more medial and highlighted in green. The long head is more lateral and highlighted in red. A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle.
