项目摘要

Variations in the paranasal sinus anatomy of extant and fossil anthropoid primates have been extensively examined using computed tomography (CT), and have potential utility for phylogenetic analyses. We used this approach to evaluate the anatomy in 18 genera of extant strepsirrhines housed in the Primate Research Institute, Kyoto University and the University of Zurich, Switzerland. The maxillary sinus is formed in all the genera. The lorisiforms have an additional pseudo-ostium opening to the nasal cavity. In Propithecus, the inferior meatus expands laterally in the region anterior to this sinus, as seen in Gorilla and Pithecia, and the maxillary sinus is segmented into three distinct chambers which have openings to the middle meatus, respectively. In Eulemur, an additional sinus-like cavity is formed in the region posterior to this sinus. Sphenoidal pneumatization with an opening to the ethmoidal region is found in all the genera, despite of differences in volume. Distinct patterns o … More f pneumatization of the frontal region are found in Eulemur, Daubentonia, Indri, Propithecus, and Avahi. The frontal sinus in Avahi communicates with the maxillary sinus. In many of the other genera, a small cavity expanding from the ethmoidal region is formed in the circumfrontal-ethmoidal region, and this feature is probably homologous to the frontal sinus. The paranasal sinuses are more variable in form in the Indridae than in the other families. The present study confirms the view that the lack of paranasal sinuses in the Old World monkeys is quite unique among the order Primates. The maxillary sinus expanding laterally into the space between the orbital floor and molar alveolar is structurally accompanied with the inferior rotation of the lower facial part against the orbital-cranial region. Such a modification contributes to the frontation of the orbits. Thus, the degree in lateral expansion of the maxillary sinus could be available for examining the orbital anthropoidization in fossil specimens. Less

已使用计算机断层扫描（CT）对延长和化石类动物原发性肾上腺鼻窦解剖结构的变化进行了广泛的检查，并具有潜在的系统发育分析的实用性。我们使用了这种方法来评估在京都大学和瑞士苏黎世大学灵长类研究所和苏黎世大学的18属延伸链球刺激属中的解剖结构。上颌窦在所有属中形成。 Lorissifers在鼻腔上有一个额外的伪孔口开口。在propithecus中，下肉在该窦前部向侧面扩展，如大猩猩和pithecia所示，上颌窦分别分为三个不同的腔室，分别在中间肉中开口。在Eulemur中，该窦后部的区域形成了一个额外的鼻窦样腔。尽管体积差异差异，但在所有属中都发现了筛子区域的螺旋肺化。在Eulemur，Daubentonia，Indri，Propithecus和Avahi中发现了额叶区域的不同模式。阿瓦希（Avahi）的额窦与上颌窦进行了交流。在许多其他属中，从筛区膨胀的小腔是在圆锥形 - 甲状腺区域中形成的，并且该特征可能与额窦同源。与其他家庭相比，在印度科中，副窦的形式更可变。本研究证实了这样一种观点，即旧世界猴子中缺乏副窦在秩序灵长类动物中非常独特。上颌窦在轨道地板和摩尔肺泡之间的空间侧面膨胀的结构在结构上伴随着下部面部针对轨道颅区域的下部旋转。这样的修改有助于轨道的前部。这是上颌窦侧膨胀的程度，可用于检查化石标本中的轨道拟型拟型拟型拟人化。较少的
