Figures 30-38 from: Senarat S, Kettratad J, Kaneko G, Kamnurdnin T, Sudtongkong C (2020) The microanatomy of the central nervous system and brain of the Indo-Pacific seahorse, Hippocampus barbouri, during development. Zoologia 37: 1-11. https://doi.org/10.3897/zoologia.37.e53734

Figures 30-38 The mylencephalon and metencephalon of Hippocampus barbouri at 35 DAB. (30) The cerebellum was found behind the optic tectum (Ote). (31) High magnification image of the cerebellum layers including the outer molecular layer (MI), Purkinje cell layer (Pl) and the inner granula layer (Gl). The prominent Purkinje cells (Pc) were observed. (32, 33) Structure and schematic diagram of the sagittal section that show the optic tectum (Ote) next to the medulla oblongata (Mo) of the myelencelphalon. (34) Vagal lobe (Vl) in the myelencephalon contained neuron (Nu) and neuroglia (Ng). (35) High magnification image showing that medulla oblongata is penetrated with the fourth ventricle (Fv). This region prominently contained neurons (Nu) and neuroglia (Ng). (36, 37) Cross section of the spinal cord (Cd) was observed, which high magnification of the accumulated neuron (Nu) was seen. The central canal (Cc) was lined by ependymal cell (Epc). (38) The ganglion (Gg) was connected with the dorsal or posterior root of the nerve fiber (Nf) originating from the spinal cord. It contained in both neuron (Nu) and satellite cell (Sac). Scale bars: 30 = 100 µm, 31, 35, 36, 37, 38 = 20 µm, 34 = 50 µm.
