(Modifiedfrom Bramwell.) M, motor fibres of the anterior root of a spinal nerve; S, S, sensory fibresof the posterior root. Note that the course of 5 and S are not the same. Some sensoryfibres pass directly through the posterior horn of the spinal gray substance, and others throughBurdachs column to read the gray substance. The direct cerebellar column is composed offibres which start in Clarkes column of cells (Fig. 33). The fibres of the two pyramidaltracts become united to the motor cells in the anterior horns of the spinal gray substance.
