Snake mouth anatomy. They smell by using their forked tongues to collect airborne particles then passing them to the vomeronasal organ or jacobsons organ in the mouth for examination. The function of undifferentiated teeth is to draw food items into the mouth rather than to chew. The nostrils are paired and open into the roof of the mouth.

This is guarded by the glottis. Unlike what mammals have the reptile glottis is always closed forming a vertical slit unless the snake takes a breath. Snake respiratory system anatomy respiratory system snakes have a small opening just behind the tongue called the glottis which opens into the trachea or windpipe.

When the mouth is closed the internal nostrils are positioned directly above the entrance to the trachea. Also the bones of the lower jaw are not fused together at the front which means they can move laterally when the snake is swallowing large prey. Snakes teeth line the inner surfaces of the upper and lower jawbones maxilla and mandible respectively.

One is attached to each mandible. Only two rows are on the lower jaw. Snakes use smell to track their prey.

Lizards differ from snakes anatomically by having their two lower jawbones fused together while the lower jawbones of the snake are connected by a flexible band of tough tissue that enables the two bones to articulate separately. The joint of the upper and lower jaws is placed very posterior far back in the skull allowing the mouth to open as wide as possible. Teeth continue to be replaced throughout life including the fangs.

The organs in the snake body are necessarily elongated to fit within the narrow confines of its body cavity. The cottonmouth snake has been considered aggressive however studies have shown that this is not necessarily true. The name cottonmouth comes from the fact that its mouth looks like cotton when it is open.

Two rows attached to the maxillary outer bones and two rows attached to the palatine and pterygoid inner bones. Called a pterygoid walk the king snake opened up its jaw and alternately ratcheted toothy parts of its upper jaw over the surface of the prey in turn walking its mouth over and around the prey. Some species of snake have virtually no teeth while others have very highly developed teeth.
