“The angle of junction of the lower and left lateral borders forms a prolongation, termed the uncinate process.”
“Her study focused on a bundle of fibers known as the uncinate fasciculus, which connects an emotion-processing area known as the amygdala, at the bottom of the brain, with a regulatory area known as the orbital prefrontal cortex, at the front of the brain.”
“Lower arrows point to complete removal of the left and right uncinate processes of the third cervical vertebrae suggestive of complete severance of the spinal column leading to full decapitation (HK43 Burial 350).”
“Microraptor/Cryptovolans has an uncinate process on its ribs which is present in all modern birds, but missing in Archaeopteryx as far as I know.”
“They are serially homologous with, for example, the uncinate processes of the ribs in birds (see Figs. 5 and 6).”
“Behind this process a broad, thin plate, the ethmoidal process, ascends to join the uncinate process of the ethmoid; from its lower border a thin lamina, the maxillary process, curves downward and lateralward; it articulates with the maxilla and forms a part of the medial wall of the maxillary sinus.”
“In the articulated skull this aperture is much reduced in size by the following bones: the uncinate process of the ethmoid above, the ethmoidal process of the inferior nasal concha below, the vertical part of the palatine behind, and a small part of the lacrimal above and in front (Figs. 158, 159); the sinus communicates with the middle meatus of the nose, generally by two small apertures left between the above-mentioned bones.”
“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.”
“The hiatus semilunaris is bounded inferiorly by the sharp concave margin of the uncinate process of the ethmoid bone, and leads into a curved channel, the infundibulum, bounded above by the bulla ethmoidalis and below by the lateral surface of the uncinate process of the ethmoid.”
“Below the bulla ethmoidalis, and partly hidden by the inferior end of the uncinate process, is the ostium maxillare, or opening from the maxillary sinus; in a frontal section this opening is seen to be placed near the roof of the sinus.”
