16
Q

As the Radial and Ulnar Arteries anastomose, what do they form?

A
  1. Superficial Palmar Arch

2. Deep Palmar Arch

17
Q

Why are superficial veins of the Upper Limb important?

A

They are commonly used for:

  1. Intravenous Injections
  2. Transfusions
  3. Drawing Blood for Testing
18
Q

Where can the Dorsal Venous Arch be found?

A

On the Dorsum (Back) of the Hand

19
Q

Where does the Cephalic Vein arise from?

A

The lateral end of the Dorsal Venous Arch

20
Q

Where does the Basilic Vein arise from?

A

The medial end of the Dorsal Venous Arch

21
Q

Where does the Median Cubital Vein shunt blood from / to?

A
  1. From the Cephalic Vein (Superficial and Lateral)
  2. To the Basilic Vein (Deep and Medial)
    Around the area of the Elbow
22
Q

At what anatomical point does the Basilic Vein move deep into the arm?

A

At the border of Teres Major

23
Q
  1. What does the Basilic Vein combine with?

2. What does this form?

A
  1. Brachial Veins

2. Axillary Vein

24
Q

How does the Cephalic Vein pass, in relation to, the Elbow?

A

Laterally

25
Q

What does the Cephalic Vein travel through it reaches the axilla?

A

Between the Deltoid and Pectoralis Major (in the Deltopectoral Groove)

26
Q

After the Cephalic Vein has passed through the Deltopectoral Groove, where does it go?

A

It enters the Axilla region, via the Calvipectoral Triangle

27
Q
  1. What does the Cephalic Vein join up with?

2. Where does this happen?

A
  1. The Axillary Vein

2. The Axilla

28
Q

Where are the Deep Veins of the Upper Limb situated?

A

Underneath the Deep Fascia

29
Q
  1. What are the deep veins found alongside?

2. What is the advantage of this?

A
  1. Deep Arteries (Brachial, Radial, and Ulnar)

2. Pulsations of the Brachial Artery help with Venous Return (Vena Comitantes)

30
Q

Are the Deep Arteries of the Upper Limb connected to the Superficial Arteries of the Upper Limb?

A

Yes, via Perforating Veins
