The two parts of the body which are made up of cartilage instead of bone are heart and ears
C ans
1. true Ribs attach directly to the sternum. False ribs attach through costal cartilage. Floating ribs have no attachment to the sternum.
2.Muscles do not push. they pull the structure. Every muscle has two ends - a fixed end where the muscle originates and a movable end which pulls some other part. The movable end is shorter and thicker and hence pulls the bone at the movable end. Muscles can only contract and relax, they cannot lengthen or elongate.
The movable end is projected out to form a tough structure referred to as a tendon which is attached to the bone. When a muscle is triggered by a nerve, contraction of the muscle occurs and it becomes thicker and shorter which causes the bone to be pulled at the movable end
