Summary
An unusual axillary artery variation was found deep to the brachial plexus, passing between nerve divisions. This anatomical finding offers insights into vascular and nerve development.
Area of Science:
- Anatomy
- Vascular Anatomy
- Neuroanatomy
Background:
- The axillary artery is a major artery in the arm, originating from the subclavian artery.
- The brachial plexus is a network of nerves that transmits impulses from the spinal cord to the shoulder and arm.
Observation:
- An aberrant axillary artery was observed descending deep beneath the brachial plexus.
- The artery coursed between the lateral and medial cords of the brachial plexus.
- It further passed between the posterior divisions, which form the posterior cord, before emerging medially.
Findings:
- The aberrant axillary artery penetrated the posterior division of the brachial plexus from superficial to deep.
- This variation suggests a deeper anatomical course relative to the brachial plexus compared to typical anatomy.
Implications:
- This anatomical variation may be explained by developmental combinations of the axillary artery and its branches.
- Understanding such variations is crucial for accurate surgical procedures and anatomical studies in the axilla.
