Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct

Chemical agents have been around for many decades and have helped in the winning of wars but have also introduce a way to killing people that almost anyone can come up with and this has allowed terrorist organizations to have more ways to terrorize people throughout the world. Chemical warfare is really where it all began in World War One from the French. Normally we hear that the Germans started this but in fact the French did and the Germans were the first to study it with great detail and use

Section 1-2 Ex. 26 Surgery vs. Splints – A study compared surgery and splinting for subjects suffering from carpal tunnel syndrome. It was found that among 73 patients treated with surgery‚ there was a 92% success rate. Among 83 patients treated with splints‚ there was a 72% success rate. Calculations using these results showed that if there really is no difference in success rates between surgery and splints‚ then there is about a 1 in 1000 chance of getting success rates like the one obtained
