Humerus
Understand what you see.
Forms the arm and participates in shoulder and elbow movement.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Rounded head faces medially, superiorly and slightly posteriorly
- Olecranon fossa lies posteriorly at the distal end
- Capitulum is lateral and trochlea is medial
