📖 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.

Vastus Medialis

Medial component of the quadriceps. Includes the VMO (vastus medialis obliquus), which is not a distinct anatomical head but a functional subdivision characterized by fiber orientation (46-52° medially vs 15-18° for VML).

Anatomy

Origin: Medial lip of linea aspera, intertrochanteric line
Insertion: VML inserts at base of patella; VMO inserts at medial margin of patella; extensive insertion into vastus intermedius aponeurosis
Action: Knee extension; VMO contributes to medial patellar tracking
Innervation: Femoral nerve, medial division (L2-L4)
Blood Supply: Femoral artery branches
