A snake has 200-400 vertebrae—it like a big spinal cord. Common names for the various types of snake dentition originate largely from older literature, but still are encountered in informal publications. [1] The venom of some opisthoglyphous snakes is strong enough to harm humans; notably, herpetologists Karl Schmidt and Robert Mertens were killed by a boomslang and a twig snake, respectively, after each underestimated the effects of the bite and failed to seek medical help. The precaudal vertebrae have a more or less high neural spine which, as a rare exception (Xenopholis), may be expanded and plate-like above, and short or moderately long transverse processes to which the ribs are attached by a single facet. Each maxilla is reduced to a nub supporting a single hollow fang tooth. In order to envenomate prey, an opisthoglyphous snake must move the prey into the rear of its mouth and then penetrate it with its fangs, presenting difficulties with large prey although they can quickly move smaller prey into position. 1 decade ago.

In snakes that have remnants of a pelvic girdle, there are typically spurs- which kind of look like small horns. They have to be if they want to survive in the wild.

The hyoid apparatus is reduced to a pair of cartilaginous filaments situated below the trachea, and united in front. Only lower animals such as insects, worms, arachnids (spiders) lack bones. The occipital condyle is either trilobate and formed by the basioccipital and the exoccipitals, or a simple knob formed by the basioccipital; the supraoccipital is excluded from the foramen magnum. That being said, snakes have far more bones than humans and other animals. However, some Boas and Pythons have vestigial or leftover pelvic bones which are called pelvic spurs.

The quadrate is usually large and elongate, and attached to the cranium through the supratemporal (often regarded as the squamosal).

Snakes have up to hundreds of ribs, which can commonly be broken or damaged throughout their life. A. Mandible with coronoid bone; nasals in sutural contact with frontals and prefrontals; transverse bone short, not projecting much beyond cranium; maxillary not half as long as mandible, which is not longer than skull (to occiput): 1.

Yes, snakes do have teeth which are found on the lower jaw, the maxilla, the palatine bone and the lateral pterygoid plate. Snakes have very many small vertebrae, which greatly help the snake move, twist and wind and therefore make them very flexible, just the same way that our spine allows us to do the same.

Aglyphous snakes are commonly called fangless; opisthoglyphous snakes rear-fanged or back-fanged; and both Proteroglyphous and Solenoglyphous snakes are referred to as front-fanged.[3][4]. Snakes have cartilage in between their joints and tendons and in their skull as well. This could cause problems for you if they cause any tearing or damage in your digestive tract.
