A reference handbook of the medical sciences, embracing the entire range of scientific and practical medicine and allied science . . into throe coinijartinonts;one lateral between the and the radix n. vagi, one middlebetween the radix n. vagi and tlie radixn. hypoglcssi, and one medial be-tween the radix n. hypoglossi and theraphe. In the lateral compartment can beseen the corpus reslifonne (12), thenueleus funicnli cuncati (13, 25), thetractus spinalis n. trigemini (lOj, andthe substantia (27). In the middle conij)arlnicnt thereare the fibrai arcuatie sujjcrticialcs later-ales (5), the nucleus olivaris inferior(6, 32), the nucleus olivaris (7, 31), the fibnc arcuatie interiue(8, 9), the formatio reticularis grisea(17, 26), the nuclei laterales (28), andthe nucleus ambiguus (29) whicli is thechief motor nucleus of origin of the and the n. glosso-pharyngeus. In the medial compartment, the dorsal surface ventrahvard, isseen the stratum interolivare lemnisci(1), the ventral superficial arcuatefibers (2), the pyramis (4), the nuclei. (2) the large bundle of white fibers onthe ventral surface is the pyramis (3).At the periphery of the pyramid a fewcells are .seen which represent a contin-uation downward of the nuclei arcuatiof the pons. If a section be taken still higher upthe relations become somewhat morecomplex (see Fig. 912). The fourthventricle has become much wider, thetwo halves of the medulla are separatedfrom each other by the raphe (20). Inthe floor of the fourth ventricle, passingfrom the middle line lateralward, areseen the nucleus n. hypoglossi (19, 21),the nucleus aUe cinereae (16, 22), thetractus solitarius (15), and the lowerportion of the nueleus n. vestibuli (23),near which are a few fibers of the fasci-culus cuneatus and some fibers of theradix descendens n. vestibuli (14).
