supraspinatus muscle in dogs

The supraspinatus is a relatively small muscle of the upper limb that takes its name from its origin from the supraspinous fossa superior to the spine of the scapula. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder. The spine of the scapula separates the supraspinatus muscle from the infraspinatus muscle, which originates below the spine. [WP,unvetted].

What the supraspinatus muscle is

The supraspinatus is a relatively small muscle of the upper limb that takes its name from its origin from the supraspinous fossa superior to the spine of the scapula. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder. The spine of the scapula separates the supraspinatus muscle from the infraspinatus muscle, which originates below the spine. [WP,unvetted]. The atlas records it as a muscle at the organ scale in the dog.

Where the supraspinatus muscle is

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

What the supraspinatus muscle connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. part of shoulder.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the supraspinatus 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.
