Lecture Notes: Appendicular Skeleton - Clavicle

Introduction

• Lecture by Professor McCurdy
• Focus on the bones of the appendicular skeleton
• Current focus: the clavicle

Clavicle Overview

• Two clavicles: right and left
• Key Markings
  • Acromial End (Acromial Extremity)
    • More rounded and slightly flatter side
    • Marks the lateral side of the bone
  • Sternal End (Sternal Extremity)
    • Pointy and slightly rounded when viewed from certain angles
    • Marks the medial side of the bone

Identifying Features

• Conoid Tubercle
  • Located near the acromial end
  • Positioned about three quarters towards the lateral side
  • Helps determine the inferior direction (points downwards)

Orientation of the Clavicle

• Establishing Directions
  • Determine superior/inferior and lateral/medial sides
  • Understand the anterior/posterior (front/back) aspect of the bone
  • The pointy bit near the acromial end points backward

Determining Right vs Left Clavicle

• Once sides and directions are established, identify:
  • Left clavicle
  • Right clavicle
• Process involves understanding anterior, inferior, lateral, and medial directions of each clavicle

Conclusion

• Proper understanding of these features aids in distinguishing between right and left clavicles in anatomical studies.
