subscapularis muscle

The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the capsule of the shoulder-joint. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the subscapularis muscle is

The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the capsule of the shoulder-joint. [WP,unvetted]. The atlas records it as a muscle at the organ scale in the human body.

Where the subscapularis muscle is

It sits within the muscular system. Positioned deliberately as part of this species body plan.

What the subscapularis muscle connects to

The atlas records 7 typed relationships for it, across 4 kinds of connection. part of rotator cuff.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the subscapularis muscle. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Questions

Where is the subscapularis muscle?
