Lateral funiculus

Lateral funiculus
Latin	funiculus lateralis medullae spinalis
Gray's	subject #185 753

The most lateral of the bundles of the anterior nerve roots is generally taken as a dividing line that separates the antero-lateral region into two parts, viz., an anterior funiculus, between the anterior median fissure and the most lateral of the anterior nerve roots; and a lateral funiculus, between the exit of these roots and the postero-lateral sulcus.

Each lateral funiculus transmits the contralateral corticospinal and spinothalamic tracts. A hemisection of the spinal cord results in transection of both ipsilateral dorsal column and lateral funiculus; this produces Brown-Sequard syndrome.
