  For demonstrating the arrangement of the connective tissue in human pineal body, this organ was observed using a maceration and scanning electron microscopic (SEM) method. The capsule of the organ was composed of collagen fiber bundles. A number of foramina framed by collagen fibers were observed on the surface of the capsule. The collagen fibers originating from the capsule formed interlobular septula and separated pineal parenchyma into 200~400 μm lobules. The capsule and septula were consisted of loosely arranged collagen fibrils. The septula possessed 20-80 μm round or oval holes through which the lobules were continuous with each other. The pineal interlobular blood vessels coursed through where three or more pineal lobules meet.
