Astrocytes Form the Blood Brain Barrier
Astrocytes Form the Blood Brain Barrier

Blood-Brain Barrier formed by endothelial cells; joined by tight junctions; protects neurons from toxic substances, allows the exchange of nutrients and waste products between neurons and blood, prevents fluctuations in composition of blood from affecting the functions of the brain; influenced by astrocytes

Ependymal
Ependymal

Ependymal cell, type of neuronal support cell (neuroglia) that forms the epithelial lining of the ventricles (cavities) in the brain and the central canal of the spinal cord. Ependymal cells also give rise to the epithelial layer that surrounds the choroid plexus, a network of blood vessels located ...

non Ciliated Ependymal Cells

Ependymal cell, type of neuronal support cell that forms the epithelial lining of the ventricles (cavities) in the brain and the central canal of the spinal cord. Ependymal cells also give rise to the epithelial layer that surrounds the choroid plexus, a network of blood vessels located in the walls of the lateral ventricles (the two largest ventricles, which occur as a pair in the cerebral hemispheres).

Satellite
Satellite

Satellite glial cells are glial cells that cover the surface of nerve cell bodies in sensory, sympathetic, and parasympathetic ganglia. Both satellite glial cells (SGCs) and Schwann cells (the cells that ensheathe some nerve fibers in the PNS) are derived from the neural crest of the embryo during development.

Schwann Cells
Schwann Cells

In general, neuroglial cells are smaller than neurons; there are about 86 billion neurons and 85 billion "non-neuronal" (glia) cells in the human male brain. Glial cells make up about half the total volume of the brain and spinal cord. ^ The ratio varies from one part of the brain to another.
