Study Notes
Gastrocnemius Muscle
- Originates from the lateral and medial condyles of the femur and the capsule of the knee.
- Inserts into the calcaneus via the Achilles tendon.
- Responsible for plantar flexion (pointing toes) and inversion of the ankle.
Soleus Muscle
- Originates from one-third of the shaft of the fibula and one-third of the medial line of the tibia.
- Inserts into the calcaneus via the Achilles tendon.
- Facilitates plantar flexion and inversion of the ankle.
Plantaris Muscle
- Originates from the lower supracondylar line of the femur and the oblique popliteal ligament of the knee joint.
- Inserts into the posterior part of the calcaneus, connecting to the Achilles tendon.
- Functions in plantar flexion of the ankle, inversion of the ankle, and flexion of the knee.
