Together with the vertebral disc, this uncinate process prevents a vertebra from sliding backwards off the vertebra below it and limits lateral flexion ( side-bending ).
22.
The head surrounds two blood vessels, the superior mesenteric artery and uncinate process which extends to the back of the superior mesenteric vein and ends at the superior mesenteric artery.
23.
The uncinate fasciculus has the longest period of development in terms of fractional anisotropy as it alone amongst the major white fibre tracks continues to develop beyond the age of 30.
24.
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 inferior nasal concha.
25.
The first step in this procedure is an uncinectomy ( also known as infundibulotomy ), which is an incision given to the uncinate process of ethmoid bone and removal of the same.
26.
The uncinate process, unlike the remainder of the organ, passes posteriorly to the superior mesenteric vein ( it can pass posteriorly to the superior mesenteric artery, but this is less common ).
27.
The last cartilage is thick and broad in the middle, due to its lower border being prolonged into a triangular hook-shaped ( uncinate ) process, which curves downward and backward between the two bronchi.
28.
A system of hook-like uncinate processes on the ribs as with the Maniraptoriformes, allowing the ribcage to move flexibly, in articulation with an ossified sternum, was absent in " Scipionyx ".
29.
When the anterior end of the uncinate process fuses with the front part of the bulla, however, this continuity is interrupted and the frontonasal duct then drains directly into the anterior end of the middle meatus.
30.
Ostrom described " Deinonychus " as being extremely birdlike, with avian features such as a furcula, large sternal plates, horizontal posture, a birdlike spine, and ossified sternal ribs and uncinate processes.
