Superficial Posterior Leg Compartment | Origins, Insertions, Etc.

This video tutorial provides an in-depth look at the posterior compartment of the leg, focusing on the superficial muscles: gastrocnemius, soleus, and plantaris. It explains their origins, insertions, actions, and innervations. The gastrocnemius and soleus form the triceps surae, crucial for plantar flexion. The plantaris, though minor, aids in proprioception. All muscles are innervated by the tibial nerve and supplied by the posterior tibial artery.
