Supraspinatus

One of four cuff muscles

Supraspinatus belongs to the rotator cuff with infraspinatus, teres minor and subscapularis.

Each has its own selectable mesh here. Open the structure list to compare them without needing to click a small or obscured surface.

From the fossa above the spine to the humerus

It arises from the supraspinous fossa and reaches the superior facet of the humeral greater tubercle; its attachment also relates to the shoulder capsule.

The capsule is absent from this model. The visible mesh is therefore not a complete map of all tissue connections.

Abduction, not a camera movement

Supraspinatus contributes to lifting the arm away from the body and stabilizing the shoulder joint.

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.

The viewer does not assign a handover angle between this muscle and the deltoid. Changing the camera or hiding the deltoid is a viewing aid, not a demonstration of muscle recruitment.

Suprascapular nerve

Its named motor supply is the suprascapular nerve.

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

Read the model

Explore supraspinatus in 3D

1. Orient the isolated muscle. Start with Back, then use Oblique. Focus selection fits the mesh into view while retaining the source pose.
2. Restore the scapula. Choose Show context and Fade others. Select Scapula, then Supraspinatus again, to compare their relative position. The scapular spine is not a separate selectable mesh.
3. Compare above and below. Select Infraspinatus in the list and open its title. Use its related link to return, or continue to the four-muscle reading block.
