Relationship
between triceps and 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.
