CAMP FOSTER, Okinawa â The U.S. Navy hospital on Camp Lester was built at the height of the Cold War, a time when the U.S. military ran the island under an occupation government and issued its own yen currency for G.I.s to spend off base.
There are six types of synovial joints: gliding, condoloid, saddle, hinge, ball and socket, and pivot joints. Gliding joints allow for smooth movement in several directions along a plane or other smooth surface.The articulation is like two plates sliding across each other. An example would be the carpal bones of the wrist, which form a gliding synovial joint.liding joints allow for smooth movement in several directions along a plane or other smooth surface.

Extension is the opposite movement, which increases the angle at the joint. Many types of synovial joint are capable of flexion and extension (hinge; ball and socket; saddle; condyloid) including the shoulder, elbow, wrist, hip and knee.n the videos above, shoulder flexion is the action of raising the arm above the head. Extension is then the downward movement. In the photo, the shoulder is in an extended position. For the knee, bending the knee is flexion, as the angle is reduced (as shown in the picture) and straightening it is called extension.
