NEUROGLIA CELLS (Rudolf Virchow, 1846) -

  • Occurs in the C.N.S.
  • The cells are less than neurons.
  • Neuroglia cells are of four types -

(i) Oligodendrocytes - Occurs in both grey & white matter. They have a few fine procells.

(ii) Astrocytes - have a number of processes.

Both are larger, also called macroglia.

(iii) Microglial cells - have small elongated cell bodies.

The cells are phagocytic & accordingly change shape.

Microglial cells are more abundant in grey matter.

(iv) Ependymal cells - They are embryonic cells for other nervous tissue cells / they are often ciliated line the cavities.
