The axis-cylinders sooneror later break up into theircomponent primitive fibrillae, which frequently interlace to formrich net-works, or terminal plexuses, within the connective tis-sue of the organ supplied ; these net-works quite often are situ-ated immediately beneath the epithelium ; in immediate proximitywith the basement membrane fine fibrillae emerge from the plexus,enter the epithelium, and terminate in pointed or club-shaped freeendings between the epithelial cells. The nerves of common sen-sation frequently end in this manner, including, probably, manynerves of the skin, cornea, and mucous membranes. Many sensory nerves, however, terminate in special endings of.
