Anatomy of the sternum and humerus in the domestic chicken (Gallus domesticus).

Injuries of the sternum and humerus are an important welfare concern in domestic chickens (Gallus domesticus), especially laying hens. Published anatomic references using standardized terminology from the Nomina Anatomica Avium (NAA) are lacking. Objectives of the current retrospective, descriptive study were to provide a user-friendly hierarchical table of NAA-compliant anatomic terms and labeled images illustrating anatomic structures for the sternum and humerus of domestic chickens. Three-dimensional model images were downloaded from a publicly accessible platform, labeled in consultation with a veterinary anatomist, and enhanced by a medical illustrator. Findings can serve as a resource for future clinical and research applications.
