The digestive tract is a long muscular tube lined with epithelium specialized for digestion and absorption of food and water. Intrinsic innervation of much of the alimentary canal is provided by the enteric nervous system, which runs from the esophagus to the anus, and contains approximately 100 million motor, sensory, and interneurons (unique to this system compared to all other parts of the peripheral nervous system). Most of the cells are absorptive cells; interspersed among them is a small number of mucus-producing goblet cells that appear as tear shaped dots of a lighter color.
