In a myelinated axon, the myelin sheath prevents the local current (small black arrows) from flowing across the membrane. This forces the current to travel down the nerve fibre to the unmyelinated nodes of Ranvier, which have a high concentration of ion channels. Upon stimulation, these ion channels propagate the action potential (large green arrows) to the next node. Thus, the action potential jumps along the fibre as it is regenerated at each node, a process called saltatory conduction. In an unmyelinated axon, the action potential is propagated along the entire membrane, fading as it diffuses back through the membrane to the original depolarized region.
The celiac ganglion is a preaortic ganglion located on the anterior surface of the aorta. It provides sympathetic innervation to several organs within the abdominal cavity by distributing axons along the major gastrointestinal arteries.1
The organs supplied by the celiac ganglion include:
