Arthroscopy joint dysfunction. TMJ arthroscopy can be a purely diagnostic procedure, or it can have its own beneficial effects which may result from washing out of the joint during the procedure, thought to remove debris and inflammatory mediators, and may enable a displaced disc to return to its correct position. Arthroscopy is also used to visualize the inside of the joint during certain surgical procedures involving the articular disc or the articular surfaces, similar to laparoscopy. Examples include release of adhesions (e.g., by blunt dissection or with a laser) or release of the disc. Biopsies or disc reduction can also be
Effect of spaceflight on the human body examined will become important. Overall, there is little data on the manifold effects of living in space, and this makes attempts toward mitigating the risks during a lengthy space habitation difficult. Test beds such as the ISS are currently being utilized to research some of these risks. The environment of space is still largely unknown, and there will likely be as-yet-unknown hazards. Meanwhile, future technologies such as artificial gravity and more complex bioregenerative life support systems may someday be capable of mitigating some risks. Effect of spaceflight on the human body Venturing into the environment of space can have negative
