What forms Kiesselbach plexus?
Kiesselbach plexus is an anastomosis with branches from both the internal and external carotid artery systems. The anterior ethmoid, greater palatine, sphenopalatine, and superior labial arteries all form a plexus of vessels in the anteroinferior nasal septum.
What arteries comprises your Kiesselbach’s Triangle area?

The anterior septal cartilage develops as the unossified portion of the perpendicular plate of the ethmoid.
What is the Crista Ethmoidalis?
bony ridge that articulates with, or provides attachment for, any part of the ethmoid bone, especially the middle nasal concha. See: ethmoidal crest of maxilla, ethmoidal crest of palatine bone. Synonym(s): crista ethmoidalis [TA]
