Gastrocnemius origin and insertion

Named for its two bellies mediallateral GASTROCNEMIUS. Proximal third of tibia and fibula.

The bulk of the gastrocnemius muscle from each of the heads come together and insert into the posterior surface of a broad membranous tendon.

Gastrocnemius origin and insertion. Key facts about the gastrocnemius muscle. Posterolateral aspect of lateral condyle of the femur Medial head. Posterior surface of medial femoral condyle popliteal surface of femoral shaft Insertion.

Posterior surface of the calcaneus via the calcaneal tendon. Tibial nerve S1 S2 Function. The medial head of the gastrocnemius arises from the medial condyle while the lateral head originates from the lateral condyle of the femur.

Insertion The gastrocnemius inserts onto the calcaneal tuberosity of the calcaneus as its both heads join with the tendon of the soleus in the midline of the lower leg in a tendon Achilles tendon. Medial condyle of femur and area above condyle. Lateral condyle of femur and area above condyle.

Achilles tendon into mid-posterior calcaneus. Functions of the gastrocnemius muscle. Origin Insertion Action Nerve Supply.

The gastrocnemius is a very potent superficial bipennate muscle that is in the back part of the lower leg muscles. It moves from its two heads just over the knee to the heel a two joint muscle. Lower posterior surface of the femur above the medial condyle.

The bulk of the gastrocnemius muscle from each of the heads come together and insert into the posterior surface of a broad membranous tendon. It then fuses with the soleus tendon to form the upper part of tendocalcaneus. Posterior surface of lateral condyle offemur and highest of three facets on lateral condyle.

Posteriorsurface of femur above medial condyle. Tendo calcaneus to middle of three facets on posterioraspect of calcaneus. The gastrocnemius originates on the lateral and medial condyle of the femur and inserts on the posterior side of the calcaneus via the Achilles tendon.

In other words the tendons of gastrocnemius and soleus fuse to form the Achilles tendon which passes behind the ankle joint and attaches to the calcaneus heel bone. The Gastrocnemius has a medial and lateral head. The origin of the medial head of the Gastrocnemius is the back of the medial femoral condyle.

The lateral head of the Gastrocnemius originates from the back of the lateral condyle of the Femur. Both heads of the Gastrocnemius come together as one to insert into the posterior surface of the Calcaneus by the. Upper 23 of the posterior surfaces of the tibia and fibula Insertion.

Posterior surface of the calcaneus via Achilles tendon Action. Plantar flexion Posterior. GASTROCNEMIUS MUSCLE ORIGIN INSERTION NERVE SUPPLY BLOOD SUPPLY AND ACTION.

Gastrocnemius -Posterior superficial -Part of Triceps Surae Medial and lateral condyles and posterior surface of femur Unites with tendon of soleus and forms the tendocalcaneus Achilles tendon to posterior surface of calcaneus Plantar flex powerful and invert Can help flex knee Tibial Soleus -Posterior superficial Head and posterior. The gastrocnemius muscle tension is transmitted not only to the foot but to the knee hip and lumbar area thanks to its fascial connections. The latter is the anatomical links with other tendons insertion and origin and the fascia covering muscles.

It is located on the back of the lower leg and originates at the posterior rear aspect of the fibular head and the medial border of the tibial shaft. The soleus muscle forms the Achilles tendon when it inserts into the gastrocnemius aponeurosis. Similarly what is the origin insertion and action of the gastrocnemius.

The origin of lateral head of gastrocnemius is from lateral surface of lateral condyle of femur the lateral supracondylar line and from capsule of knee joint. The tendon of this muscle fuses with the tendon of the soleus to form yhe tendoachilles which is inserted into the middle one-third of the posterior surface of the calcaneum. Gastrocnemius tendonitis is inflammation of the gastrocnemius tendon.

It is one of the calf muscles at the back of the lower leg. It is an overuse injury which is more common in runners and sprinters. Symptoms include gradual onset pain at the back of the knee.

Tenderness will be felt at the origin of the calf muscle just behind the knee. The gastrocnemius muscle is one of the calf muscles triceps surae in the superficial posterior compartment of the leg which sits superficial to the much larger soleus muscleIt gives the calf its distinctive two-headed appearance and is a primary plantar flexor. Its medial border of the lateral head and its lateral border of the medial head forms the inferolateral and inferomedial borders of.

Origin and insertion Plantaris is a long slender muscle that consists of a short fusiform belly 7-10 cm and a long thin tendon extending inferiorly. It originates from the inferior end of the lateral supracondylar line of femur just superior to the lateral head of the gastrocnemius muscle. Lateral head from the lateral supracondyloid crest of the femur.

The medial head from the medial supracondyloid crest. Calcaneus as part of the common calcaneal tendon Action. Extends the tarsus assists in flexing the stifle.

Terms in this set 20 GASTROCNEMIUS. Named for its two bellies mediallateral GASTROCNEMIUS. Superficial muscle of the posterior leg calf region GASTROCNEMIUS.

Medial and lateral femoral condyles posterior surface Insertion. Calcaneous via calcaneal or Achilles tendon. The gastrocnemius G.

Kneme leg or gastroc for short is the largest muscle in the calf which acts on both the ankle and knee joints. It shares the role of prime mover in ankle plantarflexion with the soleus but only when the knee is straightThe gastroc becomes less active the more the knee joint is bent. Origin of Gastronemius muscle.

Posterolateral aspect of lateral condyle of the femur. Posterior surface of medial femoral condyle popliteal surface of femoral shaft Both heads have attachments from the knee joint capsule and from the oblique popliteal ligament. Insertion of Gastronemius muscle.

Posterior surface of the calcaneus via the calcaneal tendon. Medial and lateral condyles of femur. Plantar flexion at ankle.

Proximal third of tibia and fibula. Dorsiflexion and inversion of ankle.
