The smallest neuroglia of the CNS is the microglia. They are small, specialized cells that act as the immune system of the brain, helping to protect and maintain the health of the neurons.
Ependymal cells are the CNS neuroglia that move cerebrospinal fluid (CSF) through the ventricles of the brain. They have cilia that help circulate CSF and are responsible for its production and circulation within the brain and spinal cord.
The most abundant neuroglia in the central nervous system (CNS) is the astrocyte. Astrocytes play various roles in supporting neuronal function, such as providing structural support, regulating the chemical environment, and contributing to the blood-brain barrier.
Oligodendrocytes are the type of neuroglia in the CNS that secrete myelin. They wrap around axons to provide insulation and facilitate faster nerve signal conduction.
Neuroglia are the supporting cells of the NS. There are four types in the central nervous system (CNS) and two types in the peripheral nervous system (PNS). They all have functions that contribute to the overall health of neuron cells.
The most abundant neuroglia in the central nervous system is the astrocyte. Astrocytes provide structural support to neurons, help regulate the extracellular environment, and play a role in the blood-brain barrier function. They also contribute to the repair and scarring processes in the brain and spinal cord after injury.
