From ribs to scapula
It arises from the upper eight or nine ribs and attaches along the medial border of the scapula on its costal surface.
These landmarks describe the anatomy; the surface does not contain labeled attachment footprints. The chest subset does not duplicate the scapula: open the human overview to compare it in the same source coordinates.

Function and nerve supply
It moves the scapula forward and contributes to upward rotation. Its nerve supply is the long thoracic nerve.
This is a static anatomy study. Nerves are described in the text but are not represented by an additional nerve layer or a simulated contraction.

Find the surface in context
Rotate toward a side or oblique view to inspect the broad surface. Select serratus anterior through the search and fade other structures when the arm or pectoral muscles obscure it.
The tooth-like rib-facing outline belongs to one muscle on each side. The source object is selectable as a whole, not as independently modeled slips.
The structure name above the viewer links to this dedicated page. Bones, Muscles and Cartilage remain independently selectable; isolating this muscle removes the surrounding context temporarily.

Read the model's limits
This left-side object retains its original BodyParts3D vertices and faces. The opposite side has its own source identifier; Anatomio has not generated a mirrored substitute.
The loaded thoracic wall remains incomplete. Intercostal muscles, fascia, vessels and thoracic organs are not included, and the lower costal-cartilage margin is incomplete. Empty areas should not be read as normal anatomical openings.

Sources and editorial status
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.
