Actions of many smooth muscles. Extrinsic control of heart. Variety of metabolic processes including release of catecholamines, glucagon, insulin, and others . Two Divisions Of ANS 1. Parasympathetic Depends on position of ganglia.
Sympathetic neurons are in the thoracolumbar spinal cord .
All autonomic preganglionic neurons make synapses with clusters of neurons called ganglia . The spinal cord has grey matter and white matter. The spinal cord has the intermedial lateral cell column which has the origin of sympathetic preganglionic neurons which send axons through ventral root where they synapse on a ganglion. The ganglion are found in a chain of ganglion that is close to spinal cord in paravertebral ganglionic chain. Sympathetic system has short preganglionics and long post ganglionic axons .
