Distribution of Nerves & Vessels in Upper Limb

Arterial Tree

• Derived Originally from Aorta
  • Asymmetric Supply between L/R Upper Limbs
    • R: Brachiocephalic Artery → Subclavian, Common Carotid
    • L: Aorta → L Subclavian → Axillary
• Posterior Scapular Region
• Axillary
• Anatomical Sequence
• Systemic Arterial Pressure
• Pulse Measurement (4)

Venous Drainage

1. Superficial
2. Deep
3. Perforating

Superficial & Deep Veins organised as Parallel lines.

Deep Follow Arterial Paths

Perforating Veins Connect Superficial → Deep

• Superficial
• Anatomical Sequence Deep

Axial Lines

• Anterior/Posterior Axial Lines
• Boundaries between Flexor/Extensor Compartments defined by Axial Lines
• Marked by Superficial Veins
  • Cephalic/Basilic
  • Greater/Lesser Saphenous (Lower Limbs)
