📖 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.
Supraspinatus
Rotator cuff muscle superior to the spine of the scapula. Initiates shoulder abduction.
Draft95%
Anatomy
- Origin
- Supraspinous fossa of scapula
- Insertion
- Greater tuberosity of humerus (superior facet)
- Action
- Initiates abduction; biphasic function (horizontal extensor/internal rotator in anterior planes; horizontal flexor/external rotator in posterior planes)
- Innervation
- Suprascapular nerve (C5-C6)
- Blood Supply
- Suprascapular artery, acromial branch of thoracoacromial artery, anterior circumflex humeral artery
