xương lưỡi hái
Definition
- Noun (Anatomy, Zoology):
- Keel bone (of a bird): The prominent, central ridge of a bird's sternum (breastbone). It serves as the main attachment point for the powerful flight muscles.
- Wishbone / Furcula (common but less precise): While sometimes informally associated, this is a different bone (the fused clavicles). The primary, accurate term for "xương lưỡi hái" is the keel of the sternum.
