How Does Your Triceps Straighten Your Elbow?
The triceps lies behind the upper arm and transmits force through its distal tendon to the olecranon of the ulna. This posterior force path helps extend the elbow; the muscle pulls rather than pushing the bone.

What the illustration shows
Navy-and-gold poster titled How Does Your Triceps Straighten Your Elbow? A large elbow cutaway labels red triceps, pale tendon, humerus, olecranon and ulna. A gold arrow follows the tendon toward the muscle. Upper-right schematic contrasts a bent ghost forearm with a straight forearm and a curved extension arrow. Lower-right enlargement shows tendon attaching to olecranon. Text explains posterior muscle position, ulna attachment and elbow straightening. Gold AllHumanBody.com and project slogan appear below.
How to interpret this poster
- The cropped view does not map all three muscle-head origins.
- Exposed porous bone and tendon-attachment texture are illustrative, not intact-surface microscopy.
- No measured lever ratio, force, range or exercise prescription.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
