What causes pain and loss of sensation in Axillary Artery Aneurysm?
Compression of the Brachial Plexus
Where are the three scapular anastomoses?
- B/t Suprascapular and Circumflex Scapular Arteries
- B/t Circumflex Scapular and Dorsal Scapular Arteries
- B/t Thoracodorsal and Dorsal Scapular Arteries
If you want to cut off blood supply to the Upper Extremity, where can place ligatures?
Bare in mind the scapular anastomoses
Before Thyrocervical Trunk or After Subscapular Arteries
The Deep Brachial Artery makes what 2 collateral arteries?
Radial Collateral Artery
Middle Collateral Artery
The Brachial Artery makes what two collateral arteries?
Superior Ulnar Collateral Artery
Inferior Ulnar Collateral Artery
What two major arteries give off the Recurrent Arteries of the Elbow Anastomosis?
Ulnar A. (Makes 3)
Radial A. (Makes 1)
What are the branches of the Ulnar Artery that help form the Elbow Anastomosis?
- Anterior Ulnar Recurrent Artery
- Posterior Ulnar Recurrent Artery
- Interosseous Recurrent Artery (via Common Interosseous Artery)
What branch of the Radial Artery helps form the Elbow Anastomosis?
Radial Recurrent Artery
What arteries anastamose with each other at the elbow?
- Superior Ulnar Collateral A. w/ Posterior Ulnar Reccurrent A.
- Inferior Ulnar Collateral A. w/ Anterior Ulnar Reccurent A.
- Middle Collateral A. w/ Interosseous Recurrent A.
- Radial Collateral A. w/ Radial Recurrent A.
What two minor Arteries feed into the Dorsal Carpal Arches?
The Anterior and Posterior Interosseous Arteries
What major Artery of the Hand is responsible for the Superficial Palmar Arterial Arch?
The Ulnar Artery
What major Artery of the Hand is responsible for the Deep Palmar Arterial Arch
The Radial Artery
When the Radial Artery ducks under the Thumb, what structure does it pass through?
The Anatomical Snuffbox
On the Dorsal side, what two Arteries come off of the Radial artery when it ducks behind the Thumb?
Dorsalis Pollicis
1st Dorsal Metacarpal Artery
The First Dorsal Metacarpal Artery comes off of the Radial Artery. What structure gives rise to the 2nd through 4th?
The Dorsal Carpal Arch
What two oddly named Arteries of the Thumb does the Radial Artery make?
Which one is Dorsal, and which one is Palmar?
Dorsal: Dorsalis Pollicis
Palmar: Princeps Pollicis
What Artery supplies the lateral side of the Second Digit?
Princeps Pollicis
What four arteries supply the Third and Fourth digits?
Two Proper Palmar Digital Arteries
Two Dorsal Digital Arteries
What do Proper Palmar Digital Arteries split off from?
Common Palmar Digital Arteries
What do Dorsal Digital Arteries split off from?
Dorsal Metacarpal Arteries
What supplies the medial side of the 5th Digit?
The medial Proper Palmar Digital Artery of the 5th Digit
The pinky does not get a medial Dorsal Digital Arteries
If the Superficial Palmar Arterial Arch was blocked, how might the Palmar side of the Digits receive blood?
Blood can flow from the Deep Palmar Arterial Arch through the Palmar Metacarpal Arteries into the Common Palmar Digital Arteries
Where might one find the Cephalic Vein?
On the lateral side of the Upper Extremity, crossing the head of the Humerus and joining in with the Scapula.
Where might one find the Median Cubital Vein?
What two Veins does it connect?
In the Antecubital Fossa
The Cephalic and Basilic Vein
What is the Axillary Vein emptied into by?
When does it become the Subclavian Vein?
Brachial Veins (Veins of the Brachial Arteries), Cephalic Vein and Basilic Vein
When it passes the First Rib
What makes the Median Cubital Vein such a good site for Venipuncture?
Because of the protective nature of the Bicipital Aponeurosis.
What is the clinical importance of Axillary Lymph Nodes?
They are frequently invaded by cancer cells.
