@rev.med: Think in 3’s and you’ll never forget the anatomy of the anatomical snuff box again. Comment ‘Anatomy’ below and we’ll send you a video lesson! In this lesson, we break down the borders, contents, and clinical relevance of this high-yield wrist region — using easy visuals and mnemonics that actually stick. What You’ll Learn: ✅ 3 Pollicis muscles forming the borders ✅ 3 key structures inside (artery, nerve, vein) ✅ 3 bones forming the floor ✅ Clinical pearls — scaphoid fracture, radial pulse, and nerve injury 🧠 High-Yield Notes (save for exams): *FOOSH + snuff box tenderness = Scaphoid fracture until proven otherwise *Retrograde blood supply → Avascular necrosis risk *Radial artery crosses the floor → Palpate pulse here *Superficial branch of radial nerve → Sensory loss on dorsum of hand *Cephalic vein → Potential venous access site REV MED
