Anatomy and Function of the Clavicle

Introduction

• Presented by Matt from Kenhub.
• Focus on the anatomy, definition, and function of the clavicle.

Clavicle Overview

• Also known as the collar bone.
• Curvy bone located at the base of the neck.
• Classified as a long bone but relatively short.

Location

• Runs from the sternum at the medial line to the acromion of the scapula.
• Present on both sides of the sternum.

Landmarks

• Inferior surface contains landmarks where ligaments attach:
  • Conoid Tubercle: Near the acromial end.
  • Trapezoid Line: Also located on the acromial end.
  • Impression for the Costoclavicular Ligament: Found on the sternal end.
• Names of bony prominences correspond to the ligaments attaching at those points.

Functions

• Attaches arms to the trunk.
• Protects neurovascular structures supplying the arm.
• Transfers force from the upper limb to the axial skeleton.

Palpation and Visibility

• Easily palpable due to its proximity to the body's surface.
• Visible in some individuals.

Clinical Note

• Most commonly fractured bone in the body.
• Functions as a stress absorber due to location and role.

Closing Remarks

• Kenhub offers more engaging learning tools than traditional textbooks.
• Additional resources available: videos, quizzes, articles, and an anatomy atlas.
• Encouragement to explore Kenhub for enhanced anatomy learning.
