See around, not just through.
The 3D subset keeps the source positions of 44 separate structures. Rotate the model, hide a layer, or isolate a structure to inspect its shape.

Shape is not photorealism.
This is a reduced-resolution model, not a complete dissection. Skin, vessels, nerves and most neighboring muscles are omitted. Colors and shading are illustrative; there are no realistic muscle-fiber textures. Anatomical review is still required.

Two heads, one muscle
Adductor pollicis lies in the deep adductor-interosseous compartment. Its oblique and transverse heads are parts of one muscle, not two independent muscles.
The source index identifies this object as the transverse head on the right. Both heads are separately selectable in this study, unlike the grouped interosseous and lumbrical source sets.

Attachment overview
The transverse head arises from the third metacarpal shaft rather than the carpal region. It reaches the base of the thumb proximal phalanx, alongside the other head.
The loaded bones provide orientation, but their attachment areas are not annotated. Tendon boundaries and fibers cannot be selected independently.
Sources: TTUHSC El Paso · hand tables
Thumb adduction
Adductor pollicis brings the thumb toward the hand. This action differs from opposition.
Rotation in this viewer moves the camera, not a joint. The two meshes remain in their original pose; the model does not demonstrate contraction or measure movement.
Sources: TTUHSC El Paso · hand tables
Nerve connection
The deep branch of the ulnar nerve supplies adductor pollicis.
Nerves and vessels are not displayed. Selecting one head does not reveal a separate nerve branch, and the visual mesh is not a clinical nerve map.

- Inspect one head. Start with the isolated structure. Rotate it and use Reset to restore the initial camera framing.
- Compare with the hand bones. Use the third metacarpal shaft as your starting landmark. Compare this source mesh with the oblique head, then isolate each in turn. Do not infer exact attachment footprints from surface overlap.
- Switch to the other head. Open the related structure below, or return to the hand overview. Each head has its own selected state and stable page address. Compare both adductor heads →

Source identification
About this model
BodyParts3D identifies this right-sided mesh as adductor pollicis · transverse head. Its source identifiers are FMA46123 and FJ1515. Colors and lighting are illustrative, not tissue textures.
Read the hand bone-group overview or open the whole upper-limb model. The hand close-up includes three thenar parts, three hypothenar muscles, two interosseous group meshes, one lumbrical group mesh, two adductor pollicis heads and six forearm muscle–tendon models, but not the other intrinsic hand muscles or complete soft tissues, accessory bones or a joint-motion simulation.
