ribcage

This term describes the anatomical enclosure of the thoracic cavity, evoking a sense of structural protection and biological fragility. It is used primarily in medical, forensic, or descriptive literary contexts to emphasize the physical barrier between the external environment and the vital organs.

While the word refers to a singular complex structure, it is treated as a standard countable noun. It does not possess the irregular pluralization found in some anatomical terms, though it is frequently paired with adjectives describing its state, such as expanded, collapsed, or shattered.
