PSA-NCAM in the human pre-term newborn medulla oblongata, rostral level (case 3). A: panoramic view of the left side dorsal quadrant at the level of the rostral hypoglossal nucleus cell column. B: dorsal cochlear nucleus; arrows point to labelled neurons. C: low-power view of the dorsomedial field of the medulla oblongata at the level of the nucleus prepositus hypoglossi (PrH). Co, dorsal cochlear nucleus; Gi, gigantocellular nucleus; icp, inferior cerebellar peduncle; IPo, interpositus hypoglossi nucleus; IR, intermediate reticular nucleus; LR, lateral reticular nucleus; mlf, medial longitudinal fasciculus; mlf, medial longitudinal fasciculus; MVe, medial vestibular nucleus; PM, paramedian reticular nucleus; PrH, prepositus hypoglossi nucleus; RO, raphe obscurus nucleus; Sol, solitary nucleus; sol, solitary tract; sp5, spinal trigeminal tract; Sp5I, spinal trigeminal nucleus, interpolar part; IV, fourth ventricle; X, dorsal motor nucleus of the vagus nerve; XII, hypoglossal nucleus. Scale bars: A, C = 500 μm; B = 100 μm.
