The neuraxon passes either direct (Fig. 8, e) into a nerve, in which case it is probably of motor nature, or it passes into a commissural nerve, which joins with the ganglion, with those located farther anterior or posterior, as is the case with all neuraxons from the very large cells (Fig. 8, d and / ). The neuraxon may pass along the same side (d) or it may cross over to the opposite side (/). From the neuraxon the dendrites branch. Fig. 9.—From the cornu Ammonis of the rabbit. A, Composite figure from preparations by S. R. j Cajah a, h, c, Association-cells whose long neuraxons split up into moss-like twigs, which invade the layer of pyramidal cells (A). At the left is a completely-sketched pyramidal cell. Through its descending neuraxon it is in relation with the "brain-pith" and through its ascending den- drites it is in relation with other systems and cells not figured. Through the asso- ciation-cells many pyramidal cells are brought into combination. off and pass into the substance of the ganglion. In their finer ramifications they are well adapted to connect together the separate elements of the whole ganglion. In the fine net-work which they form, appear nerve-fibers which come either from the peripheral-sensory nerves (3 a), or come from other ganglia.
