📖 Static demo — read-only snapshot
You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:
- Global search (sidebar) is disabled — it queries the API.
- The JSON API and the API “Try it” playgroundaren’t included.
- The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.
Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.
Gracilis
Most superficial adductor. Crosses both hip and knee. Part of pes anserinus. Commonly harvested as free muscle flap.

Anatomy
- Origin
- Body and inferior ramus of pubis
- Insertion
- Medial surface of proximal tibia (pes anserinus)
- Action
- Hip adduction, knee flexion, knee internal rotation
- Innervation
- Obturator nerve (L2-L3)
- Blood Supply
- Main pedicle from medial femoral circumflex or profunda femoris (~10 cm from origin); 1-3 distal branches from superficial femoral artery
