The main goal of this work was to investigate the general distribution of arterial blood around and inside the vomeronasal organ (VNO) of the cat.
Macro- and microdissection methods together with light and scanning electron microscopy were used. Heads were injected with an India ink/agar mixture (the VNO subsequently being cut in transverse, sagittal and horizontal sections), with clear latex (the VNO subsequently being cut in transverse sections), or with an epoxy resin to obtain casts for examination by scanning electron microscopy.
Dissection and microdissection show that the infraorbital, minor palatine, and descending palatine arteries have a common origin, rostral to the Rete mirabile arteria maxillaris. In transverse series and in the rostral half of the VNO, an arteriole is consistently observed between the vomeronasal duct and the lateral sheet of the vomeronasal cartilage. In this same segment, arterial branches with different orientations (perpendicular, horizontal, or transverse with respect to the main axis of the organ) are observed. Scanning electron microscopy of arterial casts shows that arterial vessels of the mucosa of the nasal septum have a direct relationship with the VNO.
Branches of the sphenopalatine artery are the chief route of blood supply to the VNO. The vomeronasal parenchyma has few arterial vessels, and these are usually situated in the same position. Differences observed between the arteries inside and outside the VNO and the dilation of both by isoproterenol support the idea that the VNO is similar to erectile tissue organs and that it may act as a physiological pump.
本研究的主要目的是调查猫犁鼻器（VNO）周围及内部动脉血的总体分布情况。
采用大体解剖和显微解剖方法，结合光学显微镜和扫描电子显微镜进行研究。向猫头部注射印度墨水/琼脂混合物（随后将VNO切成横切面、矢状面和水平面）、透明乳胶（随后将VNO切成横切面）或环氧树脂以获取铸型，用于扫描电子显微镜检查。
解剖和显微解剖显示，眶下动脉、腭小动脉和腭降动脉有一个共同的起源，位于上颌动脉奇网的前方。在横切面系列以及VNO的前半部分，在犁鼻管和犁鼻软骨外侧片之间始终观察到一条小动脉。在同一节段，观察到具有不同方向（相对于器官主轴垂直、水平或横向）的动脉分支。动脉铸型的扫描电子显微镜检查显示，鼻中隔黏膜的动脉血管与VNO有直接关系。
蝶腭动脉分支是VNO的主要血液供应途径。犁鼻实质内动脉血管较少，且通常位于相同位置。VNO内外动脉之间观察到的差异以及异丙肾上腺素对两者的扩张作用支持了VNO类似于勃起组织器官且可能充当生理泵的观点。
