Excerpt from Logical Bulletin of the Marine Biological Laboratory, Woods Holl, Mass., 1905, Vol. 9The posterior pharyngeus is a strong bundle of muscular fibers arching over the mouth of the (esophagus between the walls of the nasal canal and that of the oesophagus (fig. I, h, and Fig. 4, h). This muscle lies just posterior to the pharyngeus muscle and when contracted closes off the oesophagus completely from the pharynx. When food reaches the posterior part of the pharynx, this muscle must relax to allow the food to pass on its way to the intestine.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
