Ligaments and tendons are both made of connective tissue and both can be torn or overstretched, but they differ in function. caused by "snoopy head" configuration of metacarpal head; collaterals looser in extension, tighten during increasing flexion. The gel can crowd the nerves and cause severe pain. Ligaments help the formation and functioning of joints. Ligaments are bands of tough elastic tissue around your joints. … The bursae, or fluid-filled sacs, serve as gliding surfaces for the tendons to reduce the force of friction as these tendons move.

How to use ligament in a sentence. The basic building blocks of a ligament are collagen fibers. Ligaments are relatively elastic, so they can stretch and contract when necessary to absorb shock under stress. The knee flexes (bends) normally to a maximum of 135 degrees and extends (straightens) to 0 degrees.
