The superficial palmar arch is formed predominantly by the
Alternative names for this arterial arch are: superficial volar arch,[1] superficial ulnar arch, arcus palmaris superficialis,[2] or arcus volaris superficialis.[3]
The arch passes across the palm in a curve (Boeckel's line) with its convexity downward,
If one were to fully extend the thumb, the superficial palmar arch would lie approximately 1 cm distal from a line drawn between the first web space to the Hook of Hamate (Kaplan's Cardinal Line). The superficial palmar arch extends more distally than the deep palmar arch. The connection between the deep and superficial palmar arterial arches is an example of anastomosis, and can be tested for using Allen's test.
Three
Four digital branches arise from this palmar arch that supplies the medial/ulnar 3 1/2 fingers.

Footnotes and references
- ^ Palmar and volar may be used synonymously, but volar is less common.
- ^ This is the official and international Latin term as defined by the Terminologia Anatomica (TA), but in English speaking countries and especially the US, superficial palmar arch is more commonly used.
- ^ Again, palmar and volar may be used synonymously, but arcus volaris superficialis does not occur in the TA, and can therefore be considered deprecated.
