title: Phagocytosis of myelin sheath fragments by dendrites.
abstract: In serial ultrathin sections of the frog spinal cord, profiles of dendritic appearance were identified that contained myelin fragment inclusions and received synaptic contacts. In a number of cases it could be established that the inclusions were derived from adjacent myelin sheaths. It is suggested that the phenomenon may refer to a turnover of the myelin sheath in which the detached myelin fragments are eliminated by dendrites.
