'', 20th ed. 1918.)]] In Anatomy , ribs ( Latin ''costae'') are the long curved Bone s which form the '''rib cage'''. Ribs surround the Chest (Latin Thorax ) of land Vertebrate s, and protect the Lung s, Heart , and other internal Organ s of the Thoracic Cavity . In Mammal s, one generally thinks of ribs only occurring in the Chest . However, fused-on remnants of ribs can be traced in development in Neck vertebrae ( Cervical Rib s) and Sacral vertebrae. In Reptile s, ribs sometimes occur in all vertebrae from the neck to the sacrum. Fish can have up to four ribs on each vertebrae and this can easily be seen in the Herring , although not all fish have this many. Humans (both male and female) have 24 ribs. SEE ALSO REFERENCES
