Anconeus The triceps brachii and
anconeus are muscles that work together to
straighten the elbow.
- The triceps is the bigger muscle with three
parts and does most of the work to extend the arm.
- The anconeus is a smaller helper muscle near
the elbow. It assists the triceps and helps stabilize the joint
during movement.
They are closely connected and often work as a team for elbow
extension and stability. - 💪
