title: The nerve endings of the glycogen body of embryonic and adult avian spinal cord: on the existence of two different varieties of nerve fibers.
abstract: The innervation of the enigmatic glycogen body in both embryonic and adult spinal cords in Gallus domesticus was investigated using frozen sections stained with the Del Rio Hortega silver method and the procedure of Cajal. Two distinct types of neural terminals were found, one appearing to be sensory associated with neurovascular glomi and the other related to the periependimary glycogen cells. The presence of nests of argentaphin cells indicates the probability of a neurosecretory function.
