Dorsal interossei are a group of muscles located in the foot that play an important role in maintaining balance and stability. These muscles are responsible for abducting and flexing the toes and are also involved in gripping and grasping movements. There are several synonyms for the term dorsal interossei, including dorsal interosseous muscles, interossei dorsales, and intrinsic muscles of the foot. These synonyms are often used interchangeably in medical literature and anatomy textbooks to refer to the same group of muscles. Understanding the function and location of the dorsal interossei is important for clinicians, sports therapists, and athletes looking to improve their foot function and performance.
