ELECTRON MICROSCOPIC DEMONSTRATION OF CONNECTIONS BETWEEN GLIA AND MYELIN SHEATHS IN THE DEVELOPING MAMMALIAN CENTRAL NERVOUS SYSTEM

Abstract
This paper demonstrates for the first time with the electron microscope that connections between myelin sheaths and glia exist in developing mammalian central nervous tissue. A perikaryon and its sheath may be separated by some distance. The connecting processes are described. Central sheath-glial relationships are discussed briefly and compared to possible correlates observed in the light microscope.
