At the top, this membrane is connected to rear surface of the greater cornua and the body of the hyoid bone (so it passes behind the posterior of the hyoid body). A mucous bursa separates the membrane and the hyoid bone, so that the larynx’s upward movement during swallowing is made easier. Continue Scrolling To Read More Below...
