They are fusiform in shape and are flattened upon the surface ofthe tendon close to its insertion into the muscular fibers. They are composedof a granular substance, enveloped in several concentric hyaline membraneswhich contain some nuclei. The nerve fiber passes into this little corpuscle,splitting itself up into fine terminals. The corpuscles of Golgi are believedto be related to the muscular sense, figure 104. THE NEUROGLIA. The neuroglia, while not a nervous tissue, is closely mingled with it andforms an important constituent of the nervous system. It consists of cellsgiving off a fine network of richly branching fibers. Neuroglia is a formof connective tissue, and it is in its functions strictly comparable to the con-nective tissue which supports the special structures of other organs
