Origin

The superficial palmar arch is formed by a venous network of palmar veins including the common palmar digital veins.

Course

The superficial and deep palmar venous arches accompany the arterial palmar arches. The common palmar digital veins join the superficial veins, while the palmar metacarpal veins join the deep venous palmar arch (Standring, 2016).

Tributaries

The superficial palmar arch receives the common palmar digital veins via a network of superficial palmar vessels. It shunts blood to the dorsal aspect of the hand via the intercapitular veins (Doyle and Botte, 2003).

Structures Drained

The superficial venous system is the primary drainage of the hand. The palmar venous drainage is insufficient and blood of the palm of the hand is drained primarily by the dorsal venous network via the intercapitular veins (Doyle and Botte, 2003, Tubbs et al., 2016).

Vein is a secreted ligand for the Drosophila EGFR receptor homolog (EGFR), and EGFR-mediated activation of the Ras/MAP kinase pathway is essential for longitduinal glial cell survival (Hidalgo et al., 2001).
