随着微型计算机断层扫描(CT)的出现,我们对鼻腔解剖的了解有了相当大的增长。最近,一种称为扩散性碘基对比增强CT(diceCT)的技术使研究鼻软组织成为可能。使用diceCT和组织学,我们的目的是(a)探索这些技术用于推断代表呼吸道粘膜的静脉窦存在的实用性,以及(B)询问血管粘膜的分布是否可能与鼻腔衍生功能的特化有关(即,鼻发射回声定位声音)。匹配的组织学和diceCT数据表明,当血细胞存在时,diceCT可以将静脉窦检测为变暗的“空”空间或不透射线的岛。因此,我们表明,diceCT提供了可靠的信息血管分布在鼻气道粘膜。在研究的蝙蝠中,一种非回声定位的翼足类动物(Cynopterus sphinx)和一种回声定位声音的口头发射器(Eptesicus fuscus)拥有静脉窦网络,这些静脉窦网络流入鼻咽口侧的蝶腭静脉。相比之下,鼻发射的河马的鼻咽通道明显充满了静脉窦。在鼻发射叶口类中,鼻咽通道的粘膜血管少得多,其中血管粘膜在鼻腔中分布更广泛,并且在一些花蜜喂养物种中,特别大的静脉窦与犁鼻器相邻。因此,我们没有发现一个共同的模式,静脉窦分布与鼻发射的声音在phyllostomids和hipposiderids。相反,血管粘膜更可能对所有蝙蝠的空气调节和犁鼻功能至关重要。
Our knowledge of nasal cavity anatomy has grown considerably with the advent of micro‐computed tomography (CT). More recently, a technique called diffusible iodine‐based contrast‐enhanced CT (diceCT) has rendered it possible to study nasal soft tissues. Using diceCT and histology, we aim to (a) explore the utility of these techniques for inferring the presence of venous sinuses that typify respiratory mucosa and (b) inquire whether distribution of vascular mucosa may relate to specialization for derived functions of the nasal cavity (i.e., nasal‐emission of echolocation sounds) in bats. Matching histology and diceCT data indicate that diceCT can detect venous sinuses as either darkened, “empty” spaces, or radio‐opaque islands when blood cells are present. Thus, we show that diceCT provides reliable information on vascular distribution in the mucosa of the nasal airways. Among the bats studied, a nonecholocating pteropodid (Cynopterus sphinx) and an oral‐emitter of echolocation sounds (Eptesicus fuscus) possess venous sinus networks that drain into the sphenopalatine vein rostral to the nasopharynx. In contrast, nasopharyngeal passageways of nasal‐emitting hipposiderids are notably packed with venous sinuses. The mucosae of the nasopharyngeal passageways are far less vascular in nasal‐emitting phyllostomids, in which vascular mucosae are more widely distributed in the nasal cavity, and in some nectar‐feeding species, a particularly large venous sinus is adjacent to the vomeronasal organ. Therefore, we do not find a common pattern of venous sinus distribution associated with nasal emission of sounds in phyllostomids and hipposiderids. Instead, vascular mucosa is more likely critical for air‐conditioning and sometimes vomeronasal function in all bats.
