Trachea are generally highly elastic but they may calcify with age. The trachealis muscle connects the ends of the incomplete rings and contracts during coughing, reducing the size of the lumen of the trachea to increase the rate of air flow. The esophagus lies posteriorly to the trachea, adjoining along the tracheoesophageal stripe. Circular horizontal bands of fibrous tissue called the annular ligaments of trachea join the tracheal rings together. The cartilaginous rings are incomplete to allow the trachea to collapse slightly so that food can pass down the esophagus. A flap-like epiglottis closes the opening to the larynx during swallowing
Papal name used by one or more legitimate popes (e.g. Benedict X was later reckoned as antipope). Immediately after a new pope is elected, and accepts the election, he is asked in Latin "By what name shall you be called?"† The new pope chooses the name by which he will be known from that point on. The senior Cardinal Deacon, or Cardinal Protodeacon, then appears on the balcony of Saint Peter's to proclaim the new pope by his birth name, and announce his papal name: <poem> Annuntio vobis gaudium magnum: Habemus Papam! Eminentissimum ac reverendissimum dominum, dominum [baptismal name], Sanctæ Romanæ Ecclesiæ
