Definitions of PALMAR ARCHES
Sort: Oldest first
The curved extremities of the radial and cubital arteries in the palm of the hand. There are two palmar arches: - the one, cubital or superficial,-grande Arcade palmaire of Chaussier, furnishes, at its convexity towards the fingers, the collateral arteries of the fingers, and the internal collateral of the thumb; the other, the radial, profound, or deep-seated,-petite Arcade palmaire of Chaussier, is deep in the palm of the hand beneath the tendons of the flexor muscles of the fingers. It gives some small branches only to the surrounding parts. The palmar veins accompany the corresponding arteries.
