It is the prime plantar flexor of the ankle joint. The Gastrocnemius has a medial and lateral head.

Origin of the gastrocnemius. Gastrocnemius originates as two heads from the femur. The medial head originates from the popliteal surface of the femoral shaft and the posterior surface of the medial condyle. The lateral head originates from a facet on the upper lateral surface of the lateral condyle of the femur where it joins the lateral supracondylar line.

Origin The gastrocnemius originates with two heads. The medial and the lateral head. The medial head of the gastrocnemius arises from the medial condyle while the lateral head originates from the lateral condyle of the femur.

The gastrocnemius muscle is a muscle located on the back portion of the lower leg being one of the two major muscles that make. 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. Gastrocnemius muscle originates from the femoral condyles and attaches to the posterior calcaneus via Achilles tendon.

It is the prime plantar flexor of the ankle joint. 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. Gastrocnemius n 1670s from Latinized form of Greek gastroknemia calf of the leg from gaster belly see gastric kneme calf of the leg from PIE kone-mo-shin leg-bone see ham n1.

So called for its form the protuberant part of the calf of the leg. Gastrocnemius forms the major bulk at the back of lower leg and is a very powerful muscle. It is a two joint or biarticular muscle and has two heads and runs from back of knee to the heel.

The definitive shape of the calf is as a result of the medial and lateral heads of the gastrocnemius which are situated at the posterior upper half of the lower leg. The gastrocnemius is composed of a lateral and medial head. The origin of the lateral head of the gastrocnemius is the lateral epicondyle of the femur lateral surface of the patella and adjacent tibia.

The medial head originates from the medial epicondyle of the femur. The plantaris is sandwiched between the two heads of the gastrocnemius. 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. Gastrocnemius muscle origin insertion and innervation. 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. The medial head of the gastrocnemius originates from the epicondyle and the posterior surface of the medial condyle of the femur. We can identify a lateral origin and a medial origin.

Assoc Prof Craig Hacking and Dr Jeremy Jones et al. 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 muscle. It gives the calf its distinctive two-headed appearance and is a primary plantar flexor.

History and Etymology for gastrocnemius. New Latin from Greek gastroknēmē calf of the leg from gastr- knēmē shank more at ham. Keep scrolling for more.

Our team at The Usage has selected the best weight bench of 2021. 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.

A muscle with its origin from the lateral and medial condyles of the femur with insertion with the soleus muscle by the Achilles tendon into the lower half of the posterior surface of the calcaneus with nerve supply from the tibial nerve and whose action causes plantar flexion of the foot. There are two heads of the gastrocnemius medial and lateral which originate at the femoral condyles and unite to form the Achilles tendon along with the soleus. The gastrocnemius crosses the knee ankle and subtalar joints before inserting on the calcaneus.

In the pathogenesis of this injury studies have associated the tearing of the medial head of the gastrocnemius muscle at the musculotendinous junction. 1 Several factors have been documented to contribute to the susceptibility of a muscle to tear including the composition of type II fibres fast contracting extension across two joints eccentric action and fusiform stretch. 4 5 6 9 The.

The medial gastrocnemius origin was involved in eight patients and the lateral origin in two patients. The MR imaging findings consisted of both uni- and multi-loculated cysts often containing numerous septations with fluid signal characteristics. It originates from the inferior end of the lateral supracondylar line of femur just superior to the lateral head of the gastrocnemius muscle.

The attachment often extends onto the. 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. What does gastrocnemius mean. The largest most prominent muscle of the calf of the leg the action of which extends the foot and bends the knee.
