Nervous System Study Guide Anatomy and Physiology Nervous System Biophysical Pathology Table1. Central nervous system Nodes of Ranvier Neurolemma Saltatory conduction Table 2. Neuroglial Cells Neuroglial cells Neuroglial cells are only found in the nervous system. There are more neuroglial cells than neurons. They support neurons and hold them together.
Neuroglial cells are capable of reproduction.
Neurons are not capable of reproduction. Therefore neuroglial cells are frequent sites of brain tumors. Astrocytes Shaped like stars. Astrocytes support neurons and phagocytize cellular debris. Oligodendrocytes Shaped like astrocytes, but they are smaller.
