Spinal Cord Astrocytes is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Spinal cord astrocytes are star-shaped glial cells that provide metabolic support, maintain extracellular ion balance, and regulate synaptic transmission in the spinal cord. They play critical roles in motor neuron health and are implicated in amyotrophic lateral sclerosis (ALS) pathogenesis. [@activitydependent2007]

Spinal Cord Astrocytes Spinal cord astrocytes are star-shaped glial cells that provide metabolic support, maintain extracellular ion balance, and regulate synaptic transmission in the spinal cord.
Location and Morphology
Spinal cord astrocytes are distributed throughout gray and white matter. They have characteristic star-shaped morphologies with multiple branching processes that ensheath synapses and blood vessels. In the ventral horn, they are closely associated with motor [neurons](/entities/neurons). [@danbolt2001]
