The Spanish word 'torácico' (meaning 'thoracic' or 'relating to the chest') comes directly from the Ancient Greek word 'θωρακικός' (thorakikós), which meant 'relating to the chest or thorax'. This is a straightforward borrowing where the Greek word was adapted to Spanish pronunciation and spelling patterns while maintaining its original anatomical meaning.

The English word 'thoracic' is a direct cognate of the Spanish 'torácico', as both come from the same Greek source. You can also see this connection in related English words like 'thorax' and 'intrathoracic'. The similarity between Spanish 'torácico' and English 'thoracic' makes this medical term easy to remember for English speakers.
