Humerus (Humerus)
Educational content only — not medical advice.
Anatomy
The arm bone from shoulder to elbow. Its spherical head sits in the shallow glenoid cavity (giving the shoulder its wide range), the radial nerve spirals along its shaft, and its distal condyles build the elbow joint with radius and ulna.
Clinical notes
A mid-shaft spiral fracture may injure the radial nerve causing wrist drop, and supracondylar fractures are classic in children after a fall on the outstretched hand.
