On which border of the flexor carpi ulnaris muscle does the ulnar artery lie?

The ulnar artery lies along the medial border of the flexor carpi ulnaris muscle. This anatomical relationship is important to understand as it has implications in both surgical procedures and clinical assessments related to the arm and forearm.

The flexor carpi ulnaris muscle has origins and insertions that allow it to flex and adduct the wrist, and the ulnar artery's position is crucial for understanding its role in blood supply to the area. Knowing that the ulnar artery is positioned medially provides insight into potential locations for vascular access and considerations during procedures that involve the flexor compartment of the forearm.
