Arteries and Veins of the Hand Flashcards
What is another name for the ulnar canal?
Guyon Canal
What is the Guyon Canal?
Space between the the pisiform and the hook of hamate.
What does the Ulnar Artery give rise to?
the deep (palmar) branch and then continues superficial to the long flexor tendons.
What does the Ulnar Artery mainly contribute to?
Superficial Palmar Arch
What does the Superficial Palmar Arch give rise to?
Three Common Palmar Digital Arteries.
Explain the path of the radial artery in the hand.
- Curves dorsally around the scaphoid and trapezium in the floor of the anatomical snuff box and
- enters the palm by passing between the heads of the 1st dorsal interosseous muscle. It then
- turns medially and passes between the heads of the AD.
- Ends by anastomosing with the deep branch of the ulnar artery to form the deep palmar arch.
Where does the radial artery end?
Deep palmar arch
What creates the Deep Palmar Arch?
the radial artery anastomosing with the deep branch of the ulnar artery
Where do the superficial and deep palmar venous arches drain?
Into the deep veins of the forearm.
Where do the dorsal digital veins drain and what does this form?
Into three dorsal metacarpal veins, which unite to for, the dorsal venous network.
What vein originates from the lateral side of the dorsal venous network?
Cephalic
What vein originates from the medial side of the dorsal venous network?
Basalic
