Scientific notes
Libelle of note
The dorsal horn consists of layer I to layer VI, including the sensory layers I-IV and the mixed layers V and VI (VI only present in the intumescences) as advocated in TA and by Sengul G, Watson C (2012) Spinal cord: regional anatomy, cytoarchitecture and chemoarchitecture. In: Mai JK, Paxinos G, eds: The Human Nervous System, 3rd ed. Elsevier, Amsterdam, pp 186-232. Layers I and II form the superficial dorsal horn, and layers III to VI the deep dorsal horn. The intermediate zone is interpreted as layer VII only, and the ventral horn consists of the layer VIII and layer IX.
According to Kuypers HGJM (1981, Anatomy of the descending pathways. Chapter 13 in Hb Physiol, The Nervous System II. American Physiological Society, Bethesda, MD), propriospinal neurons, the intermediates between descending pathways and spinal motoneurons, can be subdivided into three groups: 1) Short propriospinal neurons with cell bodies located in the lateral parts of Laminae V-VII, with a range of 6-8 segments; 2) Intermediate propriospinal neurons with cell bodies mainly in the central part of Lamina VII, and axons extending over a subtotal number of cord segments (C>L; Th>S); 3) Long propriospinal neurons with cell bodies in the medial part of Lamina VII and in Lamina VIII, and extending over the whole extent of spinal cord segments.
