The craniocervical-mandibular system works in harmony and allows different functional tasks as the postural control of the cervical region. This system is formed by the temporomandibular joint, the masticatory muscles and ligaments connecting the temporomandibular joint and the cervical region. It has been seen to affect human posture, and many disorders of the temporomandibular joints may affe...

Background: This manuscript, the sixth in a series, discusses an investigation into production of lingua-alveolar stop consonants /tʌ/ and /dʌ/ by a person with congenital aglossia (PwCA), and the specific anatomical and physiological properties and kinematics involved. Methods: In this study, a modified barium swallow study was performed to analyze the PwCA's oral and pharyngeal tract, in addi...

To the Editor: We appreciate the comment provided by Gun et al regarding our recently published manuscript. We agree that the digastric and stylohyoid muscles are found lateral to the lingual artery as based on embryologic origins as well as previously described anatomic dissections. We contend, however, that the dissections presented do indeed show the posterior belly of the digastric. The ima...

-4BSTRACT The comparative functional anatomy of feeding in Polypterus senegalus, Lepisosteus oculatus, and Amia calva, three primitive actinopterygian fishes, was studied by high-speed cinematography (200 frames per second) synchronized with electromyographic recordings of cranial muscle activity. Several characters of the feeding mechanism have been identified as primitive for actinopterygian ...

After the divergence of chondrichthyans and teleostomes, the structure of the feeding apparatus also diverged leading to alterations in the suction mechanism. In this study we investigated the mechanism for suction generation during feeding in white-spotted bamboo sharks, Chiloscyllium plagiosum and compared it with that in teleosts. The internal movement of cranial elements and pressure in the...
