superficial palmar arterial arch

su·per·fi·cial pal·mar ar·ter·i·al arch

(sū'pĕr-fish'ăl pahl'măr ahr-tēr'ē-ăl ahrch)
The arterial arch in the hand located superficial to the long flexor tendons approximately at the level of a line extrapolated across the palm from the distal side of the outstretched thumb. It is formed principally by the termination of the superficial ulnar artery and is usually completed by a communication with the superficial palmar branch of the radial artery. The arch gives rise to the common palmar digital arteries.
Synonym(s): arcus volaris superficialis.
