Extensoren des Unterschenkels

The video tutorial provides an in-depth analysis of the extensor and fibular muscle groups in the lower leg. It covers the anatomy, origins, and functions of key muscles such as the tibialis anterior, extensor digitorum longus, extensor hallucis longus, fibularis longus, and fibularis brevis. The tutorial explains the movements these muscles facilitate, including dorsal extension, supination, pronation, and plantar flexion, and highlights the role of nerves in muscle function.

Which two groups of muscles are discussed in the introduction of the lower leg muscles?
