Clavicle

A connection between trunk and shoulder

The clavicle is the curved anterior bone of the shoulder girdle. It supports the shoulder away from the trunk and transfers forces toward the sternum.

Begin by inspecting the selected bone alone. Gold indicates selection, not a special tissue type or a damaged region.

Two ends with different neighbors

The sternal end is medial; the flatter acromial end is lateral. A curved shaft connects them.

Rotate the isolated model to compare the ends rather than assigning medial and lateral from screen left and right. Restoring the scapula gives a more useful orientation cue.

Sternoclavicular and acromioclavicular joints

Medially, the clavicle meets the sternal manubrium at the sternoclavicular joint. Laterally, it meets the scapular acromion at the acromioclavicular joint.

The scapula is loaded here, but the sternum is not. Do not interpret the unsupported medial end as the complete chest-side anatomy.

Front, Back and Oblique change the camera only. The bone positions stay fixed; this scene does not demonstrate joint motion, cartilage contact or ligament tension.

Connect the bone guide to the muscle guide

The clavicular part of deltoid begins on the lateral third of this bone.

That part is available in the structure list. Compare it with Clavicle using Fade others, then open its separate guide. The highlighted bone is not an outline of the deltoid attachment footprint.

This is one selected attachment relationship, not a complete catalog of the muscles and ligaments connected to the clavicle.

Explore clavicle in 3D

1. Compare the ends. Use Oblique and drag the isolated bone. Focus selection fits the whole clavicle back into view if you lose its outline.
2. Restore the shoulder-side neighbor. Choose Show context, select Clavicle, and enable Fade others. Switch between Clavicle and Scapula to inspect their adjacent ends.
3. Add the selected muscle relationship. Choose Deltoid · clavicular part from the list. Open its title to continue with its attachments and action; return through the related bone link.
