Forearm Word Doc Arteries Flashcards
Where are arteries of the forearm derived from?
Radial & Ulnar Branches of brachial artery and cubital fossa
—Brachial artery divides in the in the cubital fossa
Which artery is continuation in a direct line of the Brachial Artery?
Radial Artery
Where does the Radial Artery travel?
Extends distally in anterior compartment to styloid process of the radius….
And then swings dorsally though anatomical snuff box
What are the branches of the Radial Artery?
Radial Recurrent Artery –anastomosis of elbow
Superficial palmar branch — thenar eminence of the thumb
Carpal Branches
Where does the ulnar artery lie?
Sweeps medially after branching form the brachial artery
In regards to the ulnar nerve where does the ulnar artery lie?
Ulnar Artery is Lateral to Ulnar Nerve
—-or you could say the Ulnar N. is Medial to the Ulnar A.
What does the ulnar artery supply?
Medial muscles of the hand and forearm
Common Flexors synovial sheaths
Ulnar nerve :)
What are the branches of the Ulnar Artery?
Anterior & Posterior Ulnar Recurrent A. - cubital asamostis
Common interosseous artery - a short branch that later divides
What two arteries does the Common interosseous artery divide into?
Anterior & Posterior Interosseous Arteries
Where does the Anterior interosseous artery pass?
Passes distally and pierces interosseous membrane to join Carpal Artery
Where does the Posterior Interosseous Artery pass?
Passes through the interosseous membrane to reach the extensor compartment
—deep to pronator teres
What branches does the posterior interosseous artery have?
Muscular Branches
Dorsal and palmar carpal arcehs
Superfical and deep palmar arches are anastomotic with which artery?
Radial Artery
What bounds the area of the anatomical snuff box?
Tendons of:
Abductor Pollicis Longs
Extensor Pollicis Longus
Extensor Pollicis Brevis
What artery passes through the Anatomical Snuff box, and in what manner?
Radial artery passes deep in this region as it passes from anterior compartment of forearm to posterior compartment
