What you will learn

  • Locate the humerus in the upper limb and orient an isolated bone.
  • Describe the surfaces, borders, and landmarks of the shaft.
  • Identify the articular surfaces, necks, tubercles, fossae, and epicondyles.
  • Locate the muscular and ligamentous attachments carried by the bone.
  • Relate its grooves and fracture levels to the neurovascular structures at risk.
