The gastrocnemius muscle is prone to spasms, which are painful, involuntary contractions of the muscle that may last several minutes. [5] A severe ankle dorsiflexion force may result in a Medial Gastrocnemius Strain (MGS) injury of the muscle, commonly referred to as a "torn" or "strained" calf muscle, which is acutely painful and disabling.

The next step of identifying the POL femoral attachment is done by locating the gastrocnemius tubercle (2.6 mm distal and 3.1 mm anterior to the medial gastrocnemius tendon attachment on the femur). If the posteromedial capsule is not intact, the POL attachment site is located 7.7 mm distal and 2.9 mm anterior to the gastrocnemius tubercle.
The plantaris closely follows the lateral head of the gastrocnemius. Its tendon runs between those of the soleus and gastrocnemius and is embedded in the medial end of the calcaneus tendon. [32] In the deep layer, the tibialis posterior has its origin on the interosseus membrane and the neighbouring bone areas and runs down behind the medial ...
The superficial portion (the gastrocnemius) gives off two heads attaching to the base of the femur directly above the knee. The deep (profundus) mass of muscle (the soleus) forms the remaining head which attaches to the superior posterior area of the tibia. The triceps surae is innervated by the tibial nerve, specifically, nerve roots L5–S2.
Posteriorly: The popliteal vein and the tibial nerve, fascia, and skin. Laterally: The biceps femoris and the lateral condyle of femur in upper part, and plantaris, lateral gastrocnemius in lower part. Medially: The semimembranosus and the medial condyle of femur in upper part, and tibial nerve, popliteal vein, medial head of gastrocnemius in ...
However this additional information must be describing location not function. Origin The bone or other structure the muscle is attached to that remains immobile during the action. The term "bone" is omitted from bone names. Insertion The attachment point of the muscle, on a bone or otherwise, that moves during the action. Artery
Biarticular muscles cross two joints in series, usually in a limb. The details of the origin (proximal attachment) and insertion (distal attachment) can play a large role in determining muscle function. For instance, the human gastrocnemius technically spans both the knee and ankle joints.
The achilles tendon, tendo calcaneus attaches distally to the calcaneual tuberosity, and arises superiorly from the triceps surae complex of the gastrocnemius and soleus muscles. Achilles tendon at foetus. The Achilles tendon connects muscle to bone, like other tendons, and is located at the back of the lower
