Electron microscopic double-labeling study in the rat indicated that projection fibers from the caudal spinal trigeminal nucleus (Vc) were distributed ipsilaterally within the supratrigeminal region (STR) capping the trigeminal motor nucleus (Tm) and made synaptic contact with neurons projecting to the contralateral Tm. Nociceptive inputs to the Vc may reflexly control, via interneurons in the STR, the activities of Tm neurons innervating the masticatory, tensor tympani, and/or tensor veli palatine muscles.
对大鼠进行的电子显微镜双标记研究表明，来自尾侧三叉神经脊束核（Vc）的投射纤维在同侧分布于覆盖三叉神经运动核（Tm）的三叉上区（STR）内，并与投射至对侧Tm的神经元形成突触联系。对Vc的伤害性输入可能通过STR中的中间神经元，反射性地控制支配咀嚼肌、鼓膜张肌和/或腭帆张肌的Tm神经元的活动。
