The brain’s supporting cells are called:
|
|
glial cells
|
|
|
mitochondria
|
|
|
neurons
|
|
|
nuclei
|
Explanation:
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: -Glial cells are the most abundant cells in the human brain and have long been considered as passive supporting cells for neurons.
Detailed explanation-3: -There are approximately 85 billion glia cells in the human brain, about the same number as neurons. Glial cells make up about half the total volume of the brain and spinal cord.
