The uncinate process can be attached to either the lateral nasal wall, on the lamina papyracea (50%), the anterior cranial fossa, on the ethmoidal roof (25%), or the middle concha (25%). The superior attachment of the uncinate process determines the drainage pattern of the frontal sinus.
Sometimes the pancreas fails to develop normally and there may be congenital defects associated with the uncinate process. The uncinate process may split and encircle the duodenum, which is known as an annular pancreas. [3] There is also a common condition called pancreas divisum where the dorsal and ventral pancreas do not fuse properly.
Uncinate process of ethmoid bone, a process located in the nasal cavity; Uncinate process of vertebra, a hook-shaped process on the lateral borders (side edges) of the superior (top) surface of the vertebral bodies of the third to the seventh cervical vertebrae; Uncinate process of pancreas, a small projection from the pancreas
The ethmoid bone (/ ˈ ɛ θ m ɔɪ d /; [1] [2] from Ancient Greek: ἡθμός, romanized: hēthmós, lit. 'sieve') is an unpaired bone in the skull that separates the nasal cavity from the brain.
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. [1] The medial surface of the labyrinth forms part of the lateral wall of the corresponding nasal cavity.
The ethmoidal labyrinth is divided by multiple obliquely oriented, parallel lamellae. The first lamellae is equivalent to the uncinate process of ethmoid bone, the second corresponds the ethmoid bulla, and the third is the basal lamella, and the fourth is equivalent to the superior nasal concha.

In anatomy, Luschka's joints (also called uncovertebral joints, neurocentral joints) [1] are formed between uncinate process or "uncus" below and uncovertebral articulation above. [2] They are located in the cervical region of the vertebral column from C3 to C7. [ 3 ]
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).
