 | | The plates are separated below by an angular cleft, the pterygoid fissure, the margins of which are rough for articulation with the pyramidal process of the palatine bone. | | | On the under surface of the vaginal process is a furrow, which is converted into a canal by the sphenoidal process of the palatine bone, for the transmission of the pharyngeal branch of the internal maxillary artery and the pharyngeal nerve from the sphenopalatine ganglion. | | | Its lateral margin is serrated and articulates with the zygomatic bone. |

| | biology - Lacrimal gland |
| | The glands produce lacrimal fluid when stimulated by parasympathetic fibers of the facial nerve via the pterygopalatine ganglion. | | | The lacrimal fluid flows through the lacrimal ducts which exit in the space between the eye and the upper eyelid. | | | Each gland is about the size of an almond (2 cm) and sits alongside the eyeball within the orbit, nestled in the lacrimal fossa of the frontal bone. |

| | Immediately above this is a smooth surface, which forms the anterior boundary of the pterygopalatine fossa, and presents a groove, for the maxillary nerve; this groove is directed lateralward and slightly upward, and is continuous with the infraorbital groove on the orbital surface. | | | The maxilla also enters into the formation of two fossae, the infratemporal and pterygopalatine, and two fissures, the inferior orbital and pterygomaxillary. | | | Each assists in forming the boundaries of three cavities, namely, the roof of the mouth, the floor and lateral wall of the nose and the floor of the orbit. |
