01 / Geometry
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.

Opponens digiti minimi of hand
Inspect this right-hand source model, restore its surrounding bones and compare it with the other newly loaded hypothenar muscles. This short guide is awaiting anatomical review.
Atlas noteAn English anatomy guide paired with original-source geometry. Sources checked; specialist anatomical review is pending.

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.

Locate the muscle
A muscle in the little-finger compartment of the palm. This is a hand model, not a foot muscle.

Attachment overview
From the hamate hook and flexor retinaculum to the fifth metacarpal shaft.
The flexor retinaculum is not loaded. Surface proximity is not a reconstructed attachment footprint.
Sources: TTUHSC El Paso · hand tables
What does it do?
Rotates the fifth metacarpal during little-finger opposition.
The viewer displays a static mesh; rotating it does not simulate this action.

Nerve connection
Its motor supply is the deep ulnar-nerve branch. Nerves are not shown.

Explore opponens digiti minimi of hand in 3D
- Inspect the source shape. Start isolated and rotate the view. Use Focus selection if the small muscle is hard to see.
- Restore its surroundings. Choose Show context, then Fade others. Compare the selected surface with the little-finger bones; overlaps alone do not establish anatomical attachment borders.
- Compare the group. Return to the hand study and search for digiti minimi. Select each of the three available hand muscles. Wrist & hand →

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.

Source identification
About this model
BodyParts3D identifies this right-sided mesh as opponens digiti minimi of hand. Its source identifiers are FMA37400 and FJ1482. 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.
