Deltoid · clavicular part

One part, not a separate muscle

The clavicular part is the anterior portion of deltoid. Here, the three parts have separate selectable meshes so that their positions can be compared.

Gold marks the selected mesh. It does not identify a separate muscle, a nerve territory or an area that is currently contracting.

Clavicle to humerus

It begins on the lateral third of the clavicle and joins the deltoid attachment at the humeral deltoid tuberosity.

Select Clavicle to highlight the whole bone, then return to this part. The viewer does not outline its attachment footprint or separate tendon from muscle tissue.

An anterior contribution to shoulder movement

Anterior deltoid fibers contribute to shoulder flexion and medial rotation.

The source pose is fixed. Turning the camera does not raise the arm or rotate the humerus within the socket; the viewer does not simulate muscle contraction or shoulder mechanics.

Compare the written action with the posterior part’s guide. Different descriptions are not a claim that each part works independently in every movement.

Supply of the deltoid muscle

The axillary nerve supplies deltoid. Arterial contributors include the posterior circumflex humeral artery and the deltoid branch of the thoracoacromial artery.

Nerves and vessels are not loaded in this subset, so the text describes connections you cannot select in the viewer.

1. Start from the front. Choose Front and inspect the isolated part. Drag to see its reverse surface; its name stays the same when the viewpoint changes.
2. Locate the clavicle. Choose Show context, then select Deltoid · clavicular part and enable Fade others. Switch between this part and Clavicle to compare their positions.
3. Compare the neighboring parts. Select the acromial and spinal parts in turn. Open a selected title to read its guide, or use the related links below.
