1.1.3. Vasculature of the Upper Limb Flashcards
What is the Axillary Artery a continuation of?
The Subclavian Artery
What does the Axillary Artery pass under to enter the Axilla?
Pectroalis Major Muscle
What is the Axillary Artery enclosed in?
The Axillary Sheath
What arteries branch off of the Axillary Artery (in the Axilla)?
- Anterior Circumflex Humeral Artery
- Posterior Circumflex Humeral Artery
- Subscapular Artery
- What is the path of the Anterior and Posterior Circumflex Arteries?
- What do they supply?
- The circle posteriorly around the Humerus
2. They supply the Shoulder region
- What does the Axillary Artery continue on as?
2. At what anatomical point does the name change?
- The Brachial Artery
2. At the level of Teres Major
What artery branch off the Brachial Artery?
The Profunda Brachii
- What is the path of the Profunda Brachii?
2. How does it terminate?
- It travels along the posterior surface of the Humerus, running in the Radial Groove
- It ends up contributing to a network of vessles at the Elbow Joint
What does the Profunda Brachii supply?
Structures in the posterior aspect of the forearm
What does the Brachial Artery run immediately posterior to?
The Median Nerve
- Where does the Brachial Artery bifurcate?
2. What does it bifurcate under?
- As it crosses the Cubital Fossa
2. Brachialis Muscle
What does the Brachial Artery bifurcate into?
- The Radial Artery
2. The Ulnar Artrery
What does the Radial Artery supply?
The posterior aspect of the Forearm
What does the Ulnar Artery supply?
The anterior aspect of the Forearm
How do the Radial and Ulnar Arteries end?
They anastomose in the hand
As the Radial and Ulnar Arteries anastomose, what do they form?
- Superficial Palmar Arch
2. Deep Palmar Arch
Why are superficial veins of the Upper Limb important?
They are commonly used for:
- Intravenous Injections
- Transfusions
- Drawing Blood for Testing
Where can the Dorsal Venous Arch be found?
On the Dorsum (Back) of the Hand
Where does the Cephalic Vein arise from?
The lateral end of the Dorsal Venous Arch
Where does the Basilic Vein arise from?
The medial end of the Dorsal Venous Arch
Where does the Median Cubital Vein shunt blood from / to?
- From the Cephalic Vein (Superficial and Lateral)
- To the Basilic Vein (Deep and Medial)
Around the area of the Elbow
At what anatomical point does the Basilic Vein move deep into the arm?
At the border of Teres Major
- What does the Basilic Vein combine with?
2. What does this form?
- Brachial Veins
2. Axillary Vein
How does the Cephalic Vein pass, in relation to, the Elbow?
Laterally
What does the Cephalic Vein travel through it reaches the axilla?
Between the Deltoid and Pectoralis Major (in the Deltopectoral Groove)
After the Cephalic Vein has passed through the Deltopectoral Groove, where does it go?
It enters the Axilla region, via the Calvipectoral Triangle
- What does the Cephalic Vein join up with?
2. Where does this happen?
- The Axillary Vein
2. The Axilla
Where are the Deep Veins of the Upper Limb situated?
Underneath the Deep Fascia
- What are the deep veins found alongside?
2. What is the advantage of this?
- Deep Arteries (Brachial, Radial, and Ulnar)
2. Pulsations of the Brachial Artery help with Venous Return (Vena Comitantes)
Are the Deep Arteries of the Upper Limb connected to the Superficial Arteries of the Upper Limb?
Yes, via Perforating Veins
