The radialis indicis artery (radial artery of index finger) is a branch of the radial artery that provides blood to the index finger.. It arises close to the princeps pollicis artery, and descends between the first dorsal interosseous muscle and the transverse head of the adductor pollicis, and runs along the lateral side of the index finger to its extremity, where it anastomoses with the ...
Proper palmar digital arteries anastomose freely in the subcutaneous tissue of the finger tips and by smaller branches near the interphalangeal joints. Dorsal branches supplied by the arteries anastomose with the dorsal digital arteries, and supply the soft parts on the back of the second and third phalanges, including the matrix of the fingernail
Here, the nerves that signal the blood vessels of the fingertips to constrict are surgically cut.

A more recent treatment for severe Raynaud's is the use of botulinum toxin.

Glomera are most numerous in the fingers and toes. The role of the glomus body is to shunt blood away from the skin surface when exposed to cold temperatures, thus preventing heat loss, and allowing maximum blood flow to the skin in warm weather to allow heat to dissipate . [ 1 ]
The diagnosis of Flammer syndrome is primarily based on the patient's history with its typical features as well as the findings of nail fold capillaroscopy. This test shows an excessive constriction (narrowing) in the smallest blood vessels (capillaries) of the fingers in response to being exposed to cold.
