Rat Stomach Tissue
Featured in this section is a three-dimensional reconstruction of rat stomach pylorus tissue stained with Alexa Fluor 488 (wheat germ agglutinin; lectins), Alexa Fluor 568 (phalloidin; actin), and DAPI (nuclei). The pylorus, divided into two parts - the pyloric antrum and the pyloric canal - is the area of the stomach that connects to the duodenum. The pyloric sphincter receives sympathetic innervations from celiac ganglion as it lets food pass from the stomach to the duodenum.
