Cathy explains the creative side:
As you can see in my art, I drew two cats. You can see the skeleton on one of them, with the bones clearly displayed. The other one looks normal, with fur and eyes, looking like any other cat you see wondering around in your neighborhood or in a pet store. If you look at the cat skeleton closely, you will realize that the bones are supporting each other. They work together, like a team.
Cathy explains the scientific side:
Bones starts out as cartilage, a flexible, connective tissue. Then it slowly develops into an organized structure and hardens, forming a skeleton. This process is called “ossification.” The skeleton needs many different parts in order to create movement and support for our body. Joints connect the bones together so we can rotate and move our body. The skeleton has two main divisions: the axial skeleton and the appendicular skeleton. The axial skeleton includes the skull, the vertebral column, and the rib cage. The skull forms a structure of our head and protects our brain. The vertebral column is also known as the backbone or spine and supports the upper body’s weight. The rib cage is a framework that protects your lungs, your heart, and other organs. The appendicular skeleton includes the shoulder and pelvis girdle, and the skeleton of the upper limb and the lower limb. The shoulder girdle is basically your shoulder joint, it is a set of bones connecting the upper limb to the axial skeleton. The pelvis girdle is a structure that supports your upper weight. The skeleton of the upper limb allows you to grab and use objects, including the skeleton of your hands and arms. The skeleton of you lower limbs allows you do create movement with your lower body like you feet and legs, so you can do things like walking or sitting down.
