Carpenter's principles of human physiology . 573 FUNCTIONS OF THE CEREBROSPINAL NERVOUS Section immediately belowOlivary bodies. dark spots may be noticed near the bottom of the posterior fissure; these areimbedded in the mass of cells forming the chief ganglionic centres of thespinal accessory nerve, though other and extremelyfine rootlets belonging to these nerves may be tracedarising from the lateral grey substance and base ofthe anterior cornu of the spinal cord or tractusintermedio-lateralis, and issuing with the posteriorroots of the Spinal nerves as low down as the sixthor seventh cervical vertebra. Fig. 217 is taken froma section made through the lower part of the Olivarybody. The posterior pyramids (b) still contain muchgrey matter, and the restiform nucleus and greytubercle of Rolando are strongly defined. The smallcentral canal has become closely approximated tothe bottom of the posterior median fissure, and oneither side of it are the ganglionic masses from which the spinal accessory nervetakes its origin, whilst immediately in front of it are two dark spots
