Abstract
The patterns of articulation between premaxilla and maxilla, maxilla and vomer, palatine and ethmoid, and maxilla and palatine are shown in microscopic cross sections of Micropterus salmoides. How the rostral cartilage, the ligaments, and articulations are involved in jaw protrusion is described. Fibrocartilage discs are found in all the joints involved in jaw protrusion. The maxilla rotates about its articulation with the vomer, apparently as a result of the stretching of the anterior ligamentum mandibulomaxillary. Anteroventral movement of the maxilla initiates movement in the lacrimoethmoidal joint. Jaw protrusion is also assisted by movement of the palatine, which is transmitted into the swing of the maxilla.
