subscapularis muscle in dogs

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 dog.

Where the subscapularis muscle is

It sits within the muscular system. Only the system is known. The position shown carries almost no spatial information.

What the subscapularis muscle connects to

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.
