Skin
The outer integumentary envelope of the body forming a protective barrier, aiding temperature regulation, and providing an external anatomical reference.
The body surface provides an outer anatomical reference. The integumentary system forms a protective barrier and contributes to sensation and temperature regulation.
The BodyParts3D reference dataset includes 5 surface structures in the integumentary layer (Skin, Lip, Eyebrow, Hair of head, and Pubic hair). By default, the outer skin envelope is hidden in the 3D viewer so internal systems are visible, and can be toggled on at any time.
Forms a continuous protective external barrier shielding underlying tissues from mechanical, chemical, and environmental exposure.
Provides an outer surface landmark reference for regional and clinical anatomy.
Contributes to cutaneous sensation and body temperature regulation.

Every anatomical structure assigned to the Body surface layer in atlas.json. Curated landmarks include a Learn more guide, and all 5 structures can be selected directly in the 3D viewer.
Launch the 3D viewer with the Body surface activated. Orbit the camera, use the Exploded View slider to separate overlapping pieces, and click individual structures to inspect their FMA reference ID and anatomical metadata.
You have not selected any structures in the Body surface inside the 3D viewer yet during this session. Click Explore in 3D or any structure card above to inspect a structure on the 3D model.
The body surface provides an outer anatomical reference around the internal organ systems.
The integumentary system forms a protective barrier and contributes to sensation and temperature regulation.
In the 3D viewer, toggling on "Body surface" reveals the external skin mesh (FMA7163).
Cutaneous sensory receptors in the skin detect touch, pressure, pain, and temperature, sending signals to the nervous system.
Superficial muscles of facial expression and neck (such as the platysma) insert directly into the dermis of the skin.
