infraspinatus muscle in dogs
The infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa. The infraspinatus is a muscle of the rotator cuff. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the infraspinatus muscle is
The infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa. The infraspinatus is a muscle of the rotator cuff. [WP,unvetted]. The atlas records it as a muscle at the organ scale in the dog.
Where the infraspinatus muscle is

Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the infraspinatus 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.
