At the junction of this surface with the front of the body is a rough eminence, the tuberosity of the ulna, which gives insertion to a part of the Brachialis; to the lateral border of this tuberosity the oblique cord is attached.

Its lateral surface presents a narrow, oblong, articular depression, the radial notch.

Its medial surface, by its prominent, free margin, serves for the attachment of part of the ulnar collateral ligament. At the front part of this surface is a small rounded eminence for the origin of one head of the Flexor digitorum superficialis muscle; behind the eminence is a depression for part of the origin of the Flexor digitorum profundus muscle; descending from the eminence is a ridge which gives origin to one head of the Pronator teres muscle.

Frequently, the Flexor pollicis longus muscle arises from the lower part of the coronoid process by a rounded bundle of muscular fibers.
