The most lateral of the bundles of the
anterior nerve roots is generally taken as a dividing line that separates the
anterolateral system into two parts. These are the
anterior funiculus, between the
anterior median fissure and the most lateral of the anterior nerve roots, and the lateral funiculus between the exit of these roots and the
posterolateral sulcus.
The lateral funiculus transmits the contralateral corticospinal and spinothalamic tracts. A lateral cutting of the spinal cord results in the transection of both ipsilateral posterior column and lateral funiculus and this produces
Brown-Séquard syndrome.
