In the ethmoid bone, a sickle shaped projection, the uncinate process, projects posteroinferiorly from the ethmoid labyrinth.Between the posterior edge of this process and the anterior surface of the ethmoid bulla, there is a two-dimensional space, resembling a crescent shape.
An uncinate process is a hook-shaped projection or protuberance from a bone or organ. It may refer to: Uncinate process of ethmoid bone, a process located in the nasal cavity
(Uncinate means hooked from Latin uncinatus, from uncinus, barb, from uncus, hook.) They are found in birds (except for screamers), reptiles, and the early amphibian Ichthyostega. [1] These processes can serve to attach scapula muscles, [1] and help to strengthen the rib cage overlapping with the rib behind them.
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body. [1] For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes).

processus uncinatus pancreatis: TA98: A05.9.01.003: TA2: 3116: FMA: 15857: Anatomical terminology [edit on Wikidata] The uncinate process is a small part of the pancreas.
The perpendicular plate of the ethmoid bone (vertical plate) is a thin, flattened lamina, polygonal in form, which descends from the under surface of the cribriform plate, and assists in forming the septum of the nose; it is generally deflected a little to one or other side.
Behind the lacrimal process of the inferior nasal conchae lies a broad, thin plate, the ethmoidal process, which ascends to join the uncinate process of the ethmoid; from its lower border a thin lamina, the maxillary process, curves downward and lateralward; it articulates with the maxilla and forms a part of the medial wall of the maxillary sinus.
The frontal process of the maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose. ...
