ARTICULARIS GENU A Fifth Quadricep Muscle

The video tutorial explores the anatomy of the quadriceps muscles, highlighting the lesser-known fifth muscle, articularis genus. It delves into the structure and function of these muscles, particularly their role in knee extension. The tutorial also discusses the articularis genus muscle, its origin, insertion, and function, emphasizing its role in moving the suprapatellar bursa. Additionally, the video explains the concept of bursa, their composition, and their function in reducing friction between muscles and bones.
