Definition
The term 'carinal' refers to something relating to a carina, which is a keel-like structure or ridge. Think of the keel of a boat ⛵️; the carina is like that ridge found in various biological structures. In anatomy, it often describes a ridge or projection. It's not a common word in everyday conversation, but you might encounter it in biology or anatomy class. It's similar to saying something is 'spinal' relating to the spine or 'nasal' relating to the nose. So, if you hear 'carinal,' think 'ridge-like'.
