Detailed explanation-1: -There are three types of glial cells in the mature central nervous system: astrocytes, oligodendrocytes, and microglial cells (Figure 1.4A-C). Astrocytes, which are restricted to the brain and spinal cord, have elaborate local processes that give these cells a starlike appearance (hence the prefix “astro”).
Detailed explanation-2: -The four types of neuroglia found in the central nervous system are astrocytes, microglial cells, ependymal cells, and oligodendrocytes.
Detailed explanation-3: -Nervous tissue contains two major cell types, neurons and glial cells. Neurons are the cells responsible for communication through electrical signals. Glial cells are supporting cells, maintaining the environment around the neurons.
