  2. Patella - Wikipedia

    en.wikipedia.org/wiki/Patella

    The primary functional role of the patella is knee extension. The patella increases the leverage that the quadriceps tendon can exert on the femur by increasing the angle at which it acts. The patella is attached to the tendon of the quadriceps femoris muscle, which contracts to extend/straighten the knee.

  3. Posterior compartment of leg - Wikipedia

    en.wikipedia.org/wiki/Posterior_compartment_of_leg

    Posterior surface of calcaneus via calcaneal tendon: Tibial nerve (S1, S2) Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris: Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus

  4. Quadriceps tendon - Wikipedia

    en.wikipedia.org/wiki/Quadriceps_tendon

    In human anatomy, the quadriceps tendon works with the quadriceps muscle to extend the leg. All four parts of the quadriceps muscle attach to the shin via the patella (knee cap), where the quadriceps tendon becomes the patellar ligament. It attaches the quadriceps to the top of the patella, which in turn is connected to the shin from its bottom ...

  5. Patellar tendon - Wikipedia

    en.wikipedia.org/wiki/Patellar_tendon

    The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the quadriceps femoris.

  6. Fascial compartments of leg - Wikipedia

    en.wikipedia.org/wiki/Fascial_compartments_of_leg

    The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]

  7. Calf (leg) - Wikipedia

    en.wikipedia.org/wiki/Calf_(leg)

    The calf (pl.: calves; Latin: sura) is the back portion of the lower leg in human anatomy. [1] The muscles within the calf correspond to the posterior compartment of the leg. The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon. Several other, smaller muscles attach ...

  8. Knee - Wikipedia

    en.wikipedia.org/wiki/Knee

    The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...

  9. Pes anserinus (leg) - Wikipedia

    en.wikipedia.org/wiki/Pes_anserinus_(leg)

    Pes anserinus tendinitis/bursitis syndrome, or pes anserine bursitis, is a cause of chronic knee pain and weakness. [3] [4] It occurs when the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury, a person can develop this ailment. This ...
