Find it in the model
Follow this muscle from the front of the hip toward the inner knee.
These two guides compare neighboring structures; they do not define a single functional muscle group.
Attachment overview
Sartorius connects the anterior superior iliac spine to the medial proximal tibia, at the pes anserinus.
Sources: Sartorius anatomy
Main actions
It flexes, abducts and externally rotates the thigh, and flexes the knee.
The viewer is a static surface study, not a muscle-contraction or joint-motion simulation.

Innervation
Femoral nerve.
Nerves are not displayed in this model.

- Inspect the selected muscle. Start with Front and isolate sartorius. Rotate the model to follow its diagonal course; Show context restores its neighbors.
- Compare the front and outer thigh. Open the two guides on the same side, or choose a muscle from the structure list and use Isolate. Source geometry remains unchanged. Left superficial thigh guides →
- Restore whole-leg context. The whole-leg study includes the tibia and the available surrounding structures. Missing fascia and other soft tissues remain missing here too. Left whole leg in 3D →
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.
