brachialis muscle in dogs

The brachialis (brachialis anticus) is a muscle in the upper arm that flexes the elbow joint. It lies just deep of the biceps brachii, and is a synergist that assists the biceps brachii in flexing at the elbow. It makes up part of the floor of the region known as the cubital fossa. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the brachialis muscle connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. a kind of muscle of arm and muscle of shoulder.

Supply and innervation

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