👉 Pterygial, also known as the pterygoid process, is a structure in the human skull that plays a significant role in the development of the eye. It is located at the base of the skull and forms part of the orbit, which is the space between the eyeball and the eyelids. This area contains two muscles, the pterygoid process muscle and the pterygoid process bulbus, which are responsible for moving the eyes to focus on different objects.
