Document Summary
Neurophysiology: the structure and functions of the cells of the nervous system. Glia cells in the nervous system that support the activities of neurons. Neurons a cell of the nervous system that is specialized for information processing and communication. Macroglia large glial cells, including astrocytes, oligodendrocytes and schwann cells. Astrocytes a large, star shaped glial cell of the central nervous system (cns), responsible for structural support, isolation of the synapse, chemical environment at the synapse and possibly communication. Star-like shape; most common; provide structural matrix for neurons. Form close connections with capillary cells of the brain, making neurovascular units. Help form blood-brain barrier by covering surface of capillaries with their endfeet. Surround and isolate the area of the synaptic gap. Form scar tissue that fills the area previously occupied by the now dead neurons and release chemicals that inhibit neural regrowth.
