Posterior compartment leg muscles

The video tutorial explains the posterior compartment muscles of the leg, dividing them into superficial and deep groups. It covers the gastrocnemius and soleus muscles in the superficial group, highlighting their role in plantar flexion and their connection to the Achilles tendon. The deep group includes the popliteus and tibialis posterior muscles, which assist in knee flexion and foot inversion. The flexor digitorum and hallucis longus muscles are also discussed, emphasizing their function in toe flexion. The tutorial concludes with a summary of common actions and innervation by the tibial nerve.

Explain the role of the tibialis posterior muscle in foot movement.

Identify the three primary muscles referred to as 'Tom, Dick, and Harry' in the context of the posterior compartment.
