The dorsal column, also known as the dorsal column medial lemniscus (DCML) pathway, deals with the conscious appreciation of fine touch, two-point discrimination, conscious proprioception, and vibration sensations from the entire body except for the head. In the spinal cord, this pathway travels in the dorsal column, and in the brainstem, it is transmitted through the medial lemniscus; hence the name dorsal column medial lemniscus pathway. Phylogenetically, this is a relatively new pathway and serves to recognize and communicate highly localizable and discriminative sensations.
背柱，也称为背柱内侧丘系（DCML）通路，负责对除头部以外的全身精细触觉、两点辨别觉、意识性本体感觉和振动觉进行有意识的感知。在脊髓中，该通路沿背柱走行，在脑干中，它通过内侧丘系传导；因此称为背柱内侧丘系通路。从系统发生学角度来看，这是一条相对较新的通路，用于识别和传递高度定位性和辨别性的感觉。
