Vertebral Column With Skull
The skull has a calvaria cut and a spring-held lower jaw. It is 44cm tall. The vertebral column forms the central part of the skeleton. It supports the skull and protects the spinal cord. It also serves as attachment for the ribs, the pectoral and pelvic girdles. The vertebral column consists of separate bones, the vertebrae.
The different vertebrae are arranged above each other. Because the separate vertebrae are attached to each other by means of fibrous cartilaginous discs they form a flexible column. Each vertebra has articular surfaces above and below, which allow articulation movement between them. The vertebral column of 33 vertebrae is divided into five regions according to their position and structure.
The five regions consist of:-
- Seven cervical (neck) vertebrae.
- Twelve thoracic (chest) vertebrae.
- Five lumbar vertebrae.
- Five fused sacral vertebrae, and Four fused vertebrae.
- It comes with an entire skull and pelvis.
