Three species of sucking lice can be found on cattle in Missouri. The longnosed cattle louse is generally a pest of young cattle and is about 1/10 inch long. The shortnosed cattle louse is about 1/16 inch long and is more often a pest of older cattle. The little blue louse is about 1/16 inch long.
A common length of the esophagus of a giraffe is about 40 inches. That compares to about 8 to 10 inches in a human being.
The esophagus transports food from the mouth to the stomach and prevents gastric or esophageal contents from moving backward into the mouth. It is a hollow tube, roughly 10 inches long; the length of the esophagus correlates with an individual's height.his lower esophageal sphincter, or LES, plays a critical role in GERD. The hollow walls of the esophagus are lined with a three-layer mucosa. The first layer is composed of soft, scalelike cells. Underneath is a supporting layer of connective tissue and then a thin layer of muscle fiber.
