The pyloric sphincter muscle regulates the flow of chyme from the stomach to the duodenum just a few mL at a time.
The pyloric sphincter regulates the passage of chyme into the duodenum (sm. intestine).
The English name is pyloric sphincter (i.e. pylori has a c at the end). The Latin is sphincter pylori. This is a sphincter muscle at the lower end of the stomach controlling the amount of food being released into the duodenum.
The pyloric sphincter, or valve, is a strong ring of smooth muscle at the end of the pyloric canal and lets food pass from the stomach to the duodenum. It receives sympathetic innervation from celiac ganglion. http://en.wikipedia.org/wiki/Pylorus
The ring like muscle that controls the flow from the stomach to the small intestine is called the pylorus or the pyloric sphincter. It is divided into two parts: the pyloric antrum which is connected to the body of the stomach and the pyloric canal which is connected to the beginning of the small intestine (the duodenum).
The spincters located in the esophagus are: the upper sphincter at the top and the lower (the cardiac sphincter) at the bottom of the esophagus. They regulate the food passing through the esophagus.
Pyloric sphincter
The ring of muscle at the entrance to the stomach is the lower esophageal sphincter. This muscle is normally contracted to close the esophagus. At the lower end of the stomach food passes through the pyloric sphincter and into the duodenum of the small intestine.
I'm unable to display images. However, the duodenum is the first part of the small intestine where bile and pancreatic secretions enter through the hepatopancreatic sphincter, also known as the sphincter of Oddi. This sphincter regulates the flow of bile and pancreatic juices into the duodenum for digestion.
