The uncinate process is a small part of the pancreas. The uncinate process is the formed prolongation of the angle of junction of the lower and left lateral borders in the head of the pancreas. The word "uncinate" comes from the Latin "uncinatus", meaning "hooked". [1]
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.
An uncinate process is a hook-shaped projection or protuberance from a bone or organ. It may refer to: It may refer to: Uncinate process of ethmoid bone , a process located in the nasal cavity
The uncinate process has also been reported in Sphenodon and fossil vertebrates including Caudipteryx, oviraptorids, dromaeosaurids, [7] [8] Confuciusornis, Chaoyangia, and Longipteryx; however it apparently does not occur in Archaeopteryx, [6] though Codd et al. (2007) reported uncinate processes in Archaeopteryx. [7]
It is bounded inferiorly and anteriorly by the sharp concave margin of the uncinate process of the ethmoid bone, superiorly by the ethmoidal bulla, and posteriorly by the ethmoidal process of the inferior nasal concha. [4] It leads into the ethmoidal infundibulum; [5] it marks the medial limit of the ethmoidal infundibulum. [3]
The frontonasal duct may or may not drain into the ethmoidal infundibulum - this is determined by the place of attachment of the uncinate process of the ethmoid bone: if the uncinate process is attached to the lateral nasal wall, the frontonasal duct will open directly into the middle nasal meatus; if otherwise, it will drain into the infundibulum.
uncinate process of pancreas - this is a small part of the pancreas that hooks around the SMA. The SMA typically runs to the left of its associated vein, the superior mesenteric vein. After passing the neck of the pancreas it starts giving off its branches.
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 ]
