Ultrasound Anatomy: Axillary Nerves

Axillary Nerves: 

1. Median Nerve 
2. Radial Nerve 
3. Ulna Nerve 
4. Musculocutaneous Nerve 

• The axillary block is performed at the level of the branches. 
• Nerves can appear hyperechoic (bright) or hypoechoic (dark). 
• Analgesia spreads locally around the median, ulnar, radial, and musculocutaneous nerve.
