The term ARM JOINTS refers to two of the body's major joints, the WRISTS and ELBOWS. The WRISTS are located at the base of the hand and are made up of eight small bones connected by ligaments and tendons. The ELBOWS are located at the midpoint of the upper arm and are composed of three bones connected by ligaments and muscles. Both joints allow for a wide range of motion and are essential for everyday activities such as writing, typing, and lifting.
