The secondary palate is an anatomical structure that divides the nasal cavity from the oral cavity in many vertebrates. In human embryology, it refers...

The development of the secondary palate commences in the sixth week of human embryonic development. It is characterised by the formation of two palatal...

opening may be on one side, both sides, or in the middle. A cleft palate occurs when the palate (the roof of the mouth) contains an opening into the nose. The...

The soft palate is part of the palate of the mouth; the other part is the hard palate. The soft palate is distinguished from the hard palate at the front...

would have allowed for more robust jaw musculature. They also have the secondary palate that other primitive therapsids lacked, except the therocephalians...

the evolution of the middle ear bones, erect limb posture, a bony secondary palate, fur, hair, and warm-bloodedness.[citation needed] While living mammal...

'reptilian', they began to develop a secondary palate, separating the mouth and nasal cavity. In early synapsids, a secondary palate began to form on the sides...

reptiles lack a secondary palate, meaning that they must hold their breath while swallowing. Crocodilians have evolved a bony secondary palate that allows...

maxilla appears to have housed sinuses. Baryonyx had a rudimentary secondary palate, similar to crocodiles but unlike most theropod dinosaurs. A rugose...

said that Scymnosaurs were likely not endothermic for the lack of a secondary palate. The higher metabolic load associated with endothermy is associated...

nostrils were positioned far back from the tip of the snout, and a rigid secondary palate on the roof of the mouth would have strengthened the jaw when feeding...

turtles (Chelonioidea), and several extinct forms, have evolved a bony secondary palate which completely separates the oral and nasal cavities. The necks of...

in the midline of the skull over a long distance, forming a closed secondary palate that stiffened the snout, and setting off the internal nostrils and...

including two replacement teeth in each socket and a very sculptured secondary palate. Oxalaia's habitat was tropical, heavily forested, and surrounded by...

maniraptoriform coelurosaurs, the secondary palate was bony and termed an osseous secondary palate. In contrast, a soft secondary palate was inferred for some other...

perhaps hares), the lack of kinesis is most likely to be related to the secondary palate, which prevents relative movement. This in turn is a consequence of...

cortical bone and deeply-set teeth. Like reptiles, gorgonopsians lack a secondary palate separating the mouth from the nasal cavity, prohibiting chewing. Anatomy...

palatine shelves that form the secondary palate. The secondary palate will endochondrally ossify to form the hard palate - the end-stage floor of the nasal...

not in most theropod dinosaurs. Oxalaia had a particularly elaborate secondary palate, while most spinosaurs had smoother ones. The teeth of spinosaurids...

their gait was semi-erect and later forms had evolved a secondary palate. A secondary palate enables the animal to eat and breathe at the same time and...

that they had long, flexible tongues. They also had a large, side secondary palate. This means that they could breathe while chewing, unlike crocodiles...

skinks include the absence of a parietal foramen, a well developed secondary palate formed by three different bones, the maxillae, vomers and palatines...

Probainognathus had a long secondary palate as it stretched all the way to the posterior end of the tooth row. The secondary palate was formed largely by the...

Those stages were characterized by: The gradual development of a bony secondary palate. Abrupt acquisition of endothermy among Mammaliamorpha, thus prior...
