WebGanglion = clusters of neuron cell bodies in the peripheral and autonomic nervous systems, as well as associated glial cells and axons. Therefore, ganglia can be distinguished from peripheral nerves by the presence of neuron cell bodies. Axons are neuronal processes specialized for electrical impulse conduction. WebLike other parts of the peripheral nervous system, these ganglia are covered by a thin connective tissue layer, essentially a perineurium. Like CNS, but unlike other (non-enteric) autonomic ganglia, these enteric ganglia exclude connective tissue, and contain only neurons and glial (supporting) cells. fly to krakow from scotland
