Question

Thoracic cage in rabbit is made up of

• A. Ribs, vertebral column and diaphragm.
• B. Ribs, diaphragm and sternum.
• C. Vertebral column, diaphragm and sternum.
• D. Ribs, vertebral column and sternum.

Answer 1

The correct option is D Ribs, vertebral column and sternum.

In mammals, like rabbit and humans thoracic vertebrae, ribs and sternum together form the rib cage. In humans, the rib cage, also known as the thoracic cage, is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the pectoral girdle (shoulder girdle), forming a core portion of the human skeleton. A typical human rib cage consists of 24 ribs, the sternum (with xiphoid process), costal cartilages, and the 12 thoracic vertebrae.
