What is the meaning of the description "aqna al-anf" (having a high-bridged nose), which was used to describe the nose of Prophet Muhammad, peace and blessings be upon him, and the nose of Imam Mahdi al-Muntadhar?

The aquiline nose is one whose bridge is raised with a hump in it. It is characterized by a long nose and a fine tip, with a hump in its middle, and its upper part elevated between the bridge and the soft part of the nose. This is one of the characteristics of the Prophet, peace and blessings be upon him, and of the Mahdi.
