The uncinate process, which is the most important structure of OMC, both prevents the direct contact of the inspired air with the maxillary sinus, acting like a shield, and plays a role in mucociliary activity [3].
What is uncinate process?
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”.
What is the function of Uncinate processes?
(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. These processes can serve to attach scapula muscles, and help to strengthen the rib cage overlapping with the rib behind them.
Is uncinate process part of the head?
The uncinate process is an extension of the inferior part of the head of the pancreas that projects medially and wraps around the superior mesenteric vessels.
What is uncinate process sinus?
The uncinate process attaches to the perpendicular process of the palatine bone and the ethmoid process of the inferior turbinate with bony spicules. The convex anterior margin is in contact with the bony lateral nasal wall and may extend up to the lacrimal bone.
What is an Uncinate in the sinus?
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.
What is uncinate process in nose?
The uncinate process is a wing or boomerang shaped piece of bone. It forms the first layer or lamella of the middle meatus. It attaches anteriorly to the posterior edge of the lacrimal bone, and inferiorly to the superior edge of the inferior turbinate.
What is duct of Wirsung?
The pancreatic duct, or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct), is a duct joining the pancreas to the common bile duct. This supplies it with pancreatic juice from the exocrine pancreas, which aids in digestion.
What does uncinate process hypertrophy mean?
Uncinate process (UP) hypertrophy commonly accompanies degenerative cervical spondylosis and can cause radiculopathy by compressing the root of the neural foramen24). They comprise a process, corresponding recess, and surrounding ligament5).
Where is the Nasofrontal duct?
frontal sinus
The nasofrontal duct is a duct connecting the infundibulum and frontal sinus.
What is the uncinate process of a vertebra?
Uncinate process is a bony projection, in the superior surface of the vertebral body, which forms the uncovertebral joint with the body of the cervical vertebra above and also forms the medial margin of the intervertebral foramen [1,6,7].
