Skull, vertebral column, ribs, and sternum form:
Correct answer: D. Axial skeleton
- A. Appendicular skeleton
- B. Hydrostatic skeleton
- C. Exoskeleton
- D. Axial skeleton
Explanation
The axial skeleton forms a vertical axis that includes the head, neck, back, and chest. It has 80 bones and consists of the skull, vertebral column, and thoracic cage. The appendicular skeleton is the portion of the skeleton of vertebrates consisting of the bones that support the appendages. There are 126 bones. The appendicular skeleton includes the skeletal elements within the limbs, as well as the supporting shoulder girdle, pectoral, and pelvic girdle. A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called the coelom. An exoskeleton is an external skeleton that supports and protects an animal's body.
