D. Lateral cartilage

CN V - V2

Which cranial nerve and its branch provides sensory innervation to the most of the nasal cavity?

CN V

A PA student noted pain at the bridge of his nose and had been told that he has “sinus” infections. He was thinking about the afferent nerve supply from this area. Which cranial nerve is the best description of the sensory nerve innervation?

Maxilla, palatine bones

Which bones contribute to the formation of the floor of the nasal cavity?

Kiesselbach’s plexus

What is the name of the plexus on the anterioinferior nasal septum?

Middle meatus

A patient has severe sinus pain due to an infection in her maxillary sinus. You determine that she has a nasal polyp blocking the opening of the sinus and thus the sinus is not draining properly. Where is the most likely location of the polyp?

What is the function of CN I (olfactory) in the innervation of the nasal cavity?

A. Sensory to medial/lateral anterior nose

B. Visceral motor, parasympathetic, innervation to nasal glands in mucosa

C. Special sensory for smell

D. Some sympathetic fibers involved in regulatory blood flow in the nasal mucosa
