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.

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.

A group, not one numbered muscle
The palmar interossei lie on the palm-facing side of the metacarpals.
BodyParts3D identifies this object as a set. Selecting any visible component highlights the whole set; the atlas has not split, renamed or reconstructed its individual members.

Attachment overview
Their attachments connect metacarpal shafts with proximal phalangeal bases and extensor expansions. Numbering conventions vary; this model does not label individual members.
Extensor expansions and separate attachment footprints are not loaded. Mesh overlap alone is not an attachment map.
Sources: TTUHSC El Paso · hand tables
Group-level action
They draw fingers toward the middle-finger axis and assist knuckle flexion and interphalangeal extension.
The scene is static. View rotation and geometric sections do not simulate finger movement or muscle contraction.

Nerve connection
The deep branch of the ulnar nerve supplies these muscles. No nerve mesh is shown.

- Inspect the complete set. Start isolated and rotate from Front to Back. Several visible surfaces can belong to the same selectable object.
- Restore the bones. Choose Show context and Fade others to compare the source set with metacarpals. A component under another surface may be hidden from that angle.
- Compare the two sets. Return to the hand study, search interossei and switch between dorsal and palmar groups. Wrist & hand →

Source identification
About this model
BodyParts3D identifies this right-sided mesh as palmar interossei of hand · group. Its source identifiers are FMA42402 and FJ1511. 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.
