The cerebellum is attached to the other parts of the brain bythree pairs of thick bands of fibers, the largest of which, themiddle peduncles, pass forward on each side to the pons Varolii,the superior peduncles passing upward at each side to the in-ferior quadrigeminal bodies of the mid-brain, and the inferior peduncles passing downward at each sideto be continued into the restiform bodiesof the medulla oblongata. The medulla oblongata is the transi-tion stage between the spinal cord andthe brain, its diameter increasing as itascends upward. The anterior and pos-terior median fissures of the spinal cordare continued up the middle of the frontand back of the medulla respectively, andlongitudinal furrows divide the anteriorsurface of the medulla into three distinctareas on each side of the median fissure,from within outward, the pyramid, theolive, a bulging eminence, and the resti-The Medulla Oblongata, form body.

THE CENTRAL NERVOUS SYSTEM 881 spinal cord is continued up the lower part of the medulla, andopens into the fourth ventricle of the brain upon the back of theupper part of the medulla, which constitutes the lowest part ofthe floor of the ventricle. The medulla is composed of nerve-fibers connecting the brain and the spinal cord, forming thewhite matter, and also irregular small masses of nerve-cells,forming the gray matter, scattered irregularly through the whitematter. The average weight of the human male brain is betweenforty-eight and forty-nine ounces, the female brain beinglighter, but only in proportion to the lighter weight of the fe-male body. Physiology of the Brain.—The functions of the cerebrum areconnected with the higher faculties, the will, the intelhgence, thesenses, the control of movements of the body, while the cere-brum has also a cont
