. The physiology of domestic animals ... Physiology, Comparative; Veterinary physiology. pm Fig. 339.—Section of the Cervical Por- tion of the Spinal Cord, showing by Differences of Shading the White Tracts Supposed to be Functionally Distinct.

A, anterior, P, posterior median fissures: flp, direct pyramidal, cp. crossed pyramidal tracts; dc, direct cere- bellar, pin, posterior median column (Goll); uz, anterior, pz, posterior root-zones. Fig. 338.—Scheme of the Conducting Paths in the Spinal at the Third Dorsal Nerve, after Flechsig. {Landois.) The black part is the gray matter, v, anterior, hw, posterior roots ; a, direct, and 7, crossed pyramidal tracts; 0, anterior column ground-bundle; c, Goll's column ; d, postero-external column; t and /, mixed lateral paths; h, direct cerebellar tracts. Of these columns, as we shall find directly, the pyramidal tracts may be traced to the anterior pyramids of the medulla oblongata, where each lateral pyramidal tract crosses to the opposite side, through the pons to the middle third of the crusta, thence to the internal capsule, where they diverge like the rays of a fan through the white matter of the cerebrum to the central convolutions. The direct cerebellar fibres may be traced to the cerebellum, reaching it through the restiform body from Clarke's column of gray cells, thus directly connecting part of the fibres of the posterior roots with the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Smith, Robert Meade, 1854-.
