1. Extension

   In kinesiology, extension is a movement of a joint that results in increased angle between two bones or body surfaces at a joint. Extension usually results in straightening of the bones or body surfaces involved. For example, extension is produced by extending the flexed elbow. Straightening of the arm would require extension at the elbow joint. If the head is tilted all the way back, the neck is said to be extended. In some anatomical muscle names, particularly with muscles of the forearm and the Cnemis, the term occurs explicitly as the second word in the Latin spelling of the name. While extension is a movement, the terms "extend" versus "flexed" refer to the final position of a body part with reference to the anatomical position of the body. For example, if an arm fully bent at the elbow is slightly extended, it will still be called "flexed" or "semiflexed", and will be called "extended" only upon complete straightening of the arm. The movement in the opposite directions is called flexion. Flexion decreases the angle between the bones of the limb at a joint, while extension increases it. With the foot, extension is usually called plantarflexion.

Examples of extension in a Sentence

1. Omare Lamrani:

   It’s a very old plane, but definitely one of the most capable, air Force has been moving toward multi-mission aircraft, but when Air Force comes to this particular mission this plane is unrivaled in Air Force ability. There is no weapon in our arsenal that offers more effective close-air support to American ground troops serving in harms way than the A-10 aircraft, - Sen. John McCain, R-Ariz. First designated for retirement in 2011, a planning document the Air Force published in mid-February reveals that 2022 is the flying branch's newest deadline for the last A-10 flight. The extension was announced by Secretary of Defense Ash Carter during a preview of the Pentagon’s budget at the Economic Club of Washington, D.C. according to the Arizona Daily Star. The venerable plane, first built for destroying Soviet tanks, has been on the chopping block since the sequester of 2011 mandated steep cuts in the Pentagon budget. Although the planes haven't been built in more than 30 years, the Department of Defense believes it can save maintenance costs by phasing them out. Air Force brass believes newer, faster aircraft like the F-16, F-15E, and, eventually, Lockheed Martin’s F-35 can do a better job of the Warthog’s mission of providing close air support to soldiers on the ground. But the Pentagon disagrees and has pushed back, leading to Air Force brass to extend the end date for a phase out. The plane has survived year-to-year, with powerful lawmakers such as Senate Armed Services Committee Chairman John McCain, R-Ariz., fighting to keep it alive.

   So we'll see how they operate once a nomination has been made, i'm confident that whoever I select, among fair-minded people, will be viewed as an imminently qualified person, and it will then be up to Senate Republicans to decide whether they want to follow the Constitution and abide by the rules of fair play that ultimately undergird our democracy and that ensure that the Supreme Court does not just become one more extension of our polarized politics. If and when that happens, our system's not going to work.
