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.
