Origin: Brachial artery.
Course: Distally from the anterior to the posterior aspect of the humerus.

Origin
The inferior ulnar collateral artery arises from the brachial artery approximately 5 cm above the elbow joint (Standring, 2016).
Course
It courses inferiorly along the brachialis, then becomes deep to the brachialis. It curves around the distal humerus and divides into an anterior and a posterior branch.
Branches
The inferior ulnar collateral artery gives an anterior and a posterior branch which anastomose with the anterior ulnar recurrent artery respectively (Standring 2016).
Supplied Structures
It contributes to anastomotic network that supplies the elbow joint.
