Posterior funiculus
Medulla spinalis - Section - English
Latin f. posterior medullae spinalis
Gray's subject #185 752
System
MeSH [1]
Gray687
Section of the medulla oblongata through the lower part of the decussation of the pyramids.
1. Anterior median fissure.
2. Posterior median sulcus.
3. Anterior column (in red), with 3’, anterior root.
4. Posterior column (in blue), with 4’, posterior roots.
5. Lateral cerebrospinal fasciculus.
6. Posterior funiculus. The red arrow, a, a’, indicates the course the lateral cerebrospinal fasciculus takes at the level of the decussation of the pyramids; the blue arrow, b, b’, indicates the course which the sensory fibers take.

The portion of the medulla spinalis which lies between the posterolateral sulcus and the posterior median sulcus is named the posterior funiculus.
