Fig. 102.—Diagram to illustrate the structure of the inferior olivary nucleus. (Cajal, Edinger.) two accessory olivary nuclei. The inferior olivary nucleus is very conspicuousin the sections of this part of the medulla (Fig. 101). It appears as a broad,irregularly folded band of gray matter, curved in such a way as to enclose awhite core, which extends into the nucleus from the medial side through anopening, known as the hilus. Considered as a whole this nucleus resembles acrumpled leather purse, with an opening, the hilus, directed medially. Sec-tions at either end of the nucleus do not include this Opening, and at thesepoints the central core of white matter is completely surrounded by the graylamina. The fibers which stream in and out of the hilus constitute the olivary 142 THE NERVOUS SYSTEM peduncle. The two accessory olives are plates of gray substance, which in trans-verse section appear as rods. The medial necessary olivary nucleus is placed be-tween the hilus of the inferio
