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.

Lumbricals of hand · group
Explore the right-hand lumbricals as a single selectable source mesh. Restore the hand context to compare the group with the finger bones and loaded flexor tendons; individual numbered muscles are not separated.

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.

One selectable group
Lumbricals are small intrinsic muscles in the central palm, associated with the long finger flexor tendons.
The source identifies this object as a set of right-hand lumbricals. Clicking one visible component selects the entire set. Separate numbered labels have not been reconstructed.

Attachment overview
They originate from flexor digitorum profundus tendons and reach the radial sides of the extensor expansions of digits two through five.
The profundus muscle–tendon model is available for context. Extensor expansions and separate attachment footprints are not loaded; apparent mesh contact is not a detailed attachment map.
Sources: TTUHSC El Paso · hand tables
Group-level action
They assist flexion at the metacarpophalangeal joints and extension at the interphalangeal joints of these four fingers.
This is a static surface study. Camera rotation, isolation and geometric sections do not simulate contraction or tendon gliding.
Sources: TTUHSC El Paso · hand tables
Nerve connection
The two radial lumbricals receive median-nerve supply through palmar digital branches; the two ulnar lumbricals are supplied by the deep branch of the ulnar nerve.
No nerve meshes are loaded. A single selectable group does not imply a single nerve supply.

- Inspect the complete set. Start isolated, then use Front, Back and Oblique to inspect the separated visible components of this one source object.
- Restore the hand. Choose Show context and Fade others to locate the group among the palm and finger structures. Search for flexor digitorum profundus to compare its loaded tendon portions.
- Compare neighboring groups. Return to the hand study and search interossei. Switch between the dorsal, palmar and lumbrical sets without changing their original positions. Wrist & hand →

Source identification
About this model
BodyParts3D identifies this right-sided mesh as lumbricals of hand · group. Its source identifiers are FMA42398 and FJ1510. 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.
