2 - They are composed of cartilage

3 - The basketball player probably has larger vertebrae in the spinal column.

4 - clavicle

5 - consists of three parts: the manubrium, the body (gladiolus) and the xiphoid process.

Step-by-step explanation:

1. In adults there are total 206 bones and are categorized into axial skeleton and appendicular skeleton bones. Vertebral bones, skull bones, sternum and ribs are part of axial skeleton. Pectoral girdle and pelvic girdle are part of appendicular skeleton.

2. Fontanels are soft spots found between the skull bones at the time of birth. They aren't composed of cartilage. We can say that the sutures between the skull bones are intersected by fontanels.

3. Since the basket ball player is two feet taller we can say that he has larger vertebrae in the spinal column

4. Thoracic cage is formed by thoracic vertebrae, ribs, sternum and coastal cartilage. It encloses the lungs and heart in thoracic cavity. Clavicle is not a part of it. Pectoral girdle consists of the clavicle the collar bone.

5. Sternum is a flat bone on the ventral side of the thoracic region. It consists of three parts. The superior part is called manubrium, the middle part is called body and the inferior part is called xiphoid process.
