Relating to or resembling a carina, which is a ridge, keel-shaped structure, or projection found in anatomy or botany.
From Latin 'carina' (keel of a ship) + '-al' (suffix indicating relation). The Latin root originally referred to the keel of a vessel, but was later applied metaphorically to keel-shaped anatomical structures, particularly in the respiratory and skeletal systems.
Your windpipe has a carinal structure called the carina that splits like a ship's bow—which is why the ancient Romans named it after a boat's keel!
