Further damage occurs in the white matter of the uncinate fasciculus. The AI and dACC are linked via a white matter tract along the uncinate fasciculus. The ventral pancreatic bud forms the pancreatic head and uncinate process. The ventral pancreatic bud develops into the pancreatic head and uncinate process. Proportionally long ossified uncinate processes are fused to the dorsal ribs. Its ribcage was not strengthened by ossified uncinate processes but cartilaginous processes were likely present. Anatomical variations in superior attachment of uncinate process and localization of frontal sinus outflow tract. Luschka's joints involve the vertebral uncinate processes. An uncinate process is a hook-shaped projection or protuberance from a bone or organ. The superior attachment of the uncinate process determines the drainage pattern of the frontal sinus. Ten pairs of dorsal ribs are preserved, and like previous specimens lack uncinate processes. The overlapping uncinate processes, which stiffen the ribcage, were very well developed. The uncinate process is a small part of the pancreas. The hiatus is bound laterally by a projection known as the uncinate process. The clade is exceptional within the living birds in lacking uncinate processes of ribs.
