Many vital muscles make their home in this part of the body, including the biceps brachii, triceps brachii, and the deltoids. it's no small wonder that students regularly have problems recalling the names of the many small muscles in the hands and forearms. With these fantastic anatomical models, students and patients alike will have a fantastic tool for easier hands-on education. Massage therapists and fitness instructors will also find these a great addition to their studios.
