Serial thin sections of the coronal dental pulp of the cat's canine tooth were cut. Parts of the sub-odontoblastic neural plexus were photographed from 100 of the sections. The plexus consists of many slender, predominantly unmyelinated nerve fibres. Many axons are incompletely sheathed by their Schwann cell. Some axons leave the Schwann cell sheath and either end in the extracellar space or return to the Schwann cell after traveling a short distance. Several axons are often seen in close contact within a single invagination of the Schwann cell. They remain in contact for up to 7 micrometer.l Both Schwann cells and axons are see to branch in this region. These features may be characteristic of nerve fibres and terminals which respond to noxious stimuli.
切取猫犬齿冠状牙髓的连续薄切片。从100个切片中拍摄了成牙本质细胞下神经丛的部分图像。该神经丛由许多细长的、主要是无髓神经纤维组成。许多轴突被施万细胞不完全包裹。一些轴突离开施万细胞鞘，要么在细胞外间隙终止，要么在短距离行走后返回施万细胞。在施万细胞的单个内陷中经常可以看到几条轴突紧密接触。它们保持接触长达7微米。在这个区域可以看到施万细胞和轴突都有分支。这些特征可能是对有害刺激作出反应的神经纤维和终末的特征。
