uncinate process การใช้

• The uncinate processes are the small white spurs about halfway along the ribs.
• Luschka's joints involve the vertebral uncinate processes.
• The tuatara is the only living tetrapod with well-developed gastralia and uncinate processes.
• Birds have uncinate processes on the ribs.
• Ten pairs of dorsal ribs are preserved, and like previous specimens lack uncinate processes.
• Although bony uncinate processes are unique to birds, cartilaginous uncinate processes are present in crocodiles.
• Although bony uncinate processes are unique to birds, cartilaginous uncinate processes are present in crocodiles.
• This is due to the presence of large sternal plates and uncinate processes, which imply flight musculature.
• The true ribs are small projections, with small, hooked bones, called uncinate processes, found on the rear of each rib.
• The dorsal pancreatic bud forms the head, neck, body, and tail, whereas the ventral pancreatic bud forms the uncinate process.
• They then fuse; the dorsal pancreatic bud becomes the tail, and isthmus of the pancreas and the ventral pancreatic bud forms the pancreatic head and uncinate process.
• 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 ).
• 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.
• 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.
• 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.
• 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 ).
• 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 ".
• 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.
• 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.
• "Caudipteryx " had uncinate processes on the ribs, birdlike teeth, a first toe which may or may not be partially reversed and overall body proportions that are comparable to those of modern flightless birds.
