    Study Notes

    Key Features of the Right Humerus

    • Greater Tubercle

      • Located on the proximal end of the humerus.
      • Serves as a site for muscle attachment, particularly for the rotator cuff muscles.

    • Lesser Tubercle

      • Positioned anteriorly compared to the greater tubercle.
      • Also a site for muscle attachment, notably for the subscapularis muscle.

    • Deltoid Tuberosity

      • A roughened area on the lateral shaft of the humerus.
      • Provides attachment for the deltoid muscle and is approximately halfway down the bone.

    • Radial Fossa

      • A shallow depression on the anterior aspect of the humerus, above the capitulum.
      • Accommodates the head of the radius during elbow flexion.

    • Coronoid Fossa

      • A deeper pit located above the trochlea on the anterior side.
      • Receives the coronoid process of the ulna when the elbow is flexed.

    • Capitulum

      • A rounded structure on the lateral side of the distal humerus.
      • Articulates with the head of the radius, playing a crucial role in elbow movement.

    • Trochlea

      • Located on the medial side of the distal humerus and shaped like a spool.
      • Connects with the ulna, facilitating elbow extension and flexion.
