Neuroanatomy and glial cells come in many types (see, for example, the nervous system section of the list of distinct cell types in the adult human body). Neurons are the information-processing cells of the nervous system: they sense our environment, communicate with each other via electrical signals and chemicals called neurotransmitters across synapses, and produce our memories, thoughts and movements. Glial cells maintain homeostasis, produce myelin, and provide support and protection for the brain's neurons. Some glial cells (astrocytes) can even propagate intercellular calcium waves over long distances in response to stimulation, and release gliotransmitters in response to changes in calcium
Glial scar the spinal cord lesion and this decrease was associated with a reduction in glial scarring. Chondroitinase ABC has been shown to degrade glial scars. Degrading the glial scar with chondroitinase has been shown to promote recovery from spinal cord injury, especially when combined with other techniques such as nerve guidance conduits, schwann cell transplants, and peripheral nerve autografts. Glial scar Glial scar formation (gliosis) is a reactive cellular process involving astrogliosis that occurs after injury to the central nervous system. As with scarring in other organs and tissues, the glial scar is the body's mechanism to protect and begin the
