"desc_en": "Spinal ganglion is made from round or oval pseudounipolar neurons.\n\nPseudounipolar neurons have large round nucleus with prominent nucleolus (green arrow). Somas of these neurons are surrounded by the satelite cells(blue circle) which provide functional and nutritional support.\n\n\n\nBody of the pseudounipolar neuron sends a dendrite, which branches in T shape manner and projects to the periphery and usualy end as a receptor, while the axonal proijects to the CNS or loops back to the spinal cord. Projections of these multipolar neurons can be visualised by e.g. impregnation with silver salts.",
