The origin, course and regions supplied by the ethmoidal arteries were studied on 30 injected adult heads. After branching off, the anterior ethmoidal artery normally makes a single smooth loop by first coursing forwards and then, reversing itself towards the anterior ethmoidal foramen, it goes into the canal portion, likewise without bend or angularity. Occasionally, a common ethmoidal artery or a common source for the ethmoidal arteries is present. Very rarely does the artery fail entirely. As a rule, the posterior ethmoidal artery arises from the ophthalmic artery. Occasionally, however, it is missing or can even very rarely arise from the A. meningea media. The artery usually crosses over the superior oblique muscle while the anterior ethmoidal artery usually goes under the same muscle. In the fossa olfactoria, the ethmoidal arteries give off their most important dura and bone branches in the anterior cranial fossa and then continue into the walls of the cavum nasi. The courses and variations along with ipsi- and contralateral anastomoses are likewise demonstrated.
在30个经灌注的成人头部标本上研究了筛动脉的起源、走行及供血区域。前筛动脉分支后，通常先向前走行，然后折返朝向筛前孔，形成一个单一的平滑环，进入管部，同样没有弯曲或成角。偶尔会出现一条总筛动脉或筛动脉的共同起源。动脉完全缺如的情况非常罕见。通常，后筛动脉起源于眼动脉。然而，偶尔它会缺如，甚至极罕见地起源于脑膜中动脉。该动脉通常跨过眼上斜肌，而前筛动脉通常走行于该肌下方。在嗅窝内，筛动脉在前颅窝发出其最重要的硬脑膜和骨分支，然后继续进入鼻腔壁。还展示了其走行和变异以及同侧和对侧的吻合情况。
