This is the point at which the trachea splits into two (left and right) principal bronchi. It is located in the region of the fourth to sixth intercostal space, though this varies with species and with respiratory phase. This position closely associates the bifurcation with the heart base. The thickened median crest initiating the bifurcation is called the tracheal carina . [ MURDOCH:1966 ]
Synonyms: bifurcatio tracheae tracheal bifurcation
