When we compare the pectoral girdle with the pelvic girdle there are many differences we see. Similarities being they both have 2 bones that they consist of. The pectoral girdle has the clavicle and scapula bones, and the pelvic girdle consists of 2 hip bones. Despite this comparison the sizes of the bones vary vastly; the pectoral bones are rather small and the pelvic bones are relatively large. We notice that the pectoral connects the upper arms to the axial skeleton. There is also a joining made up of muscle and ligament which enables us to have a greater range of motion. The pelvic girdle consists of the hip bones, the sacrum and the coccyx. The pelvis has four points of articulation, which means it provides us with less mobility than the…show more content… These joints allow the body to move in different ways and can be described as planar, hinge, pivot, condyloid, saddle, or ball-and-socket joints. It is our Planar or plane joints that give us the function of limited gliding movements between the bones. Their structure is somewhat flat or slightly curved. Hinge joints are slightly-rounded on one side of the end bone and fits slightly into the hollow end of the other bone. The elbow is a great example of a hinge joint. This particular joint is referred to as being a door hinge for the reason being one bone moves while the other remains stationary. Pivot joints allow for rotational movement around an axis, for example when we move our head side to side, and rotation. Condyloid joints allow angular movement along two axes. This is best seen in the wrist and fingers, which can move side to side and up and down. Saddle joints allow angular movement as well, but with a much greater range of motion. A great example of a saddle joint would be the thumb joint which can move around freely. Lastly the ball and socket joint which possesses a ball-like end of the bone fitting into a cup like socket end of the other bone. The hip and shoulder joints are the only ball-and-socket joints of the
