Right rhomboid major

Spine and scapula landmarks

Its spinal attachment is associated with the spinous processes of T2–T5. On the scapula, it reaches the medial border below the root of the scapular spine.

These are anatomical orientation points, not labeled attachment footprints on this surface. The scapula retains its upper-limb page; use the human overview to compare it with this muscle in shared source coordinates.

Scapular action and nerve supply

The rhomboids draw the scapula toward the spine and assist its downward rotation. Their innervation is through the dorsal scapular nerve.

This viewer shows a static source position. It does not calculate scapular motion, muscle force or nerve paths; the text is an anatomical guide, not a movement simulation.

Compare the rhomboid pair

Compare its broader surface with rhomboid minor above it. Major and minor are separate named muscles, not two newly cut pieces of the same source mesh.

Choose Back or Oblique to inspect the posterior aspect. Search for rhomboid to find all four side-specific objects, then use Isolate or Fade others. Side labels refer to the person modeled, not the screen.

What this study includes

Each muscle on each side has its own indexed BodyParts3D object. The original vertices and faces are retained; Anatomio has not made a mirrored substitute or divided a larger surface.

The back region contains these four muscle meshes, thoracic and lumbar vertebrae and the sacrum. Scapulae are visible in the human overview, not this subset. Other back muscles, cervical vertebrae, fascia, discs, nerves and vessels are not represented here.

1. Inspect from behind. Use Back, then rotate toward Oblique to examine the original surface.
2. Compare its partner. Open the other rhomboid on the same side below, then compare the opposite side.
3. Restore shoulder-girdle context. Use the common human scene to see the scapulae and trunk together. Human body →

This guide uses independently written explanations with links to the evidence behind them. Source checking and specialist anatomical review are separate steps; the latter is still pending.
