The cells which are situated in thecourse of peripheral nerves are often somewhat spindle-shaped, the twojDoles of the spindle being prolonged into nerve fibres. Fig. Fig. 144. Two NERVE-CKLLS FROM THE SPINAL CORD OF THE OX, ISOLATED AFTER MACERA-TION IN VERY DILUTE CHROMIC ACID. MAGNIFIED 175 DIAMETERS. () Tilach cell has a well-defined, clear, round nucleus, and a large niicleolus. The cellprocesses are seen to be finely fibrillated, the fibrils passing from one process into anotherthrough the l)ody of the cell. A, from the anterior cornu of grey matter, large andstellate, with numerous processes ; a, axis-cylinder process broken a short distance fromthe cell. B, probably from the posterior cormi, more fusiform in shape and apparently-destitute of an axis-cylinder process. I NERYE-CELLS. 147
