In recent years, some taxonomic controversy has occurred over the genus of North American rat snakes. Based on mitochondrial DNA, Utiger et al. (2002) showed that North American rat snakes of the genus Elaphe, along with closely related genera such as Pituophis and Lampropeltis, form a monophyletic group separate from Old World members of the genus.
A pinched nerve is a type of injury or damage to a nerve or a group of nerves. The injury can result from compression, constriction, or stretching. A pinched nerve can lead to other conditions and cause temporary or permanent damage depending on the extent of the injury. pinched nerve is a type of injury or damage to a nerve or a group of nerves.

A simple physiological principle is that we need to stretch to maintain functional muscle length. Short, tight muscles can cause a number of problems including joint dysfunction, circulation problems, poor posture, and as in the case of piriformis syndrome, nerve entrapment.So, one solution to piriformis syndrome is to stretch regularly.y regular readers know that a subluxation is a stuck joint with neurological implications. In other words, subluxations hamper free movement and can cause nerve pain and/or dysfunction. Chronic or long-term subluxations, then, can lead to piriformis syndrome.
