Uncinate process of ethmoid bone

From Wikipedia, the free encyclopedia

Bone: Uncinate process of ethmoid bone
Lateral wall of nasal cavity, showing ethmoid bone in position.(Unciate process of ethmoid labeled at left.)

In the ethmoid bone, a curved lamina, the uncinate process, projects downward and backward from this part of the labyrinth; it forms a small part of the medial wall of the maxillary sinus, and articulates with the ethmoidal process of the inferior nasal concha.
