Abstract

The sphincter derives a certain amt. of motor innervation through the lumbar sympathetic outflow. The majority of the fibers concerned are postganglionic fibers arising in the inferior mesenteric ganglion. A few motor fibers are not interrupted in the inferior mesenteric ganglion. Inhibitory fibers from the lumbar sympathetic outflow pass to the sphincter by way of the hypogastric nerves.
