口腔亚核
Pars oralis nuclei spinalis nervi trigeminalis
- 拉丁语近义词: Subnucleus oralis
定义
三叉神经脊束核口侧部是该神经核最吻侧的部分,向上延伸至脑桥被盖。它接收来自面部中线附近区域的痛觉和温度觉信息,涵盖口腔及鼻腔区域。
为充分理解这一概念,需了解三叉神经脊束核与三叉神经脊束在空间上呈自上而下的躯体定位组织方式。在脊束核的躯体定位排列中,面部中央区或口周区域在神经核中的投射位置较靠吻侧(即神经核上部)。随着区域向外侧延伸(即离口部越远),其在三叉神经脊束核中的投射位置越靠尾侧(即神经核下部)。这种躯体定位组织方式将三叉神经脊束核由吻侧至尾侧划分为三个亚部:口侧部、极间部及尾侧部。
