Musculus pterygoideus medialis

The video tutorial discusses the medial pterygoid muscle, a key component of the chewing muscles. It covers the muscle's origin, approach, innervation, and functions. The medial pterygoid, also known as the inner wing muscle, originates in the Fossa Perrigo idea and attaches to the wedge leg. It works with the masseter muscle to form a loop around the lower jaw, aiding in jaw elevation and protrusion. The muscle is innervated by the mandibular nerve, facilitating its role in mastication.
