up the majority of the skeletal system in turtles as opposed to amphibians
who have a large amount of cartilage in their system. Connective tissue
in the turtles is mineralized and becomes bone and the interior of their
bones consists of sponge like marrow. In some cases the marrow inside the
bones produces both red and white blood cells (Dawson 2000).
The turtle skeleton is divided into two main sections, the endoskeleton and the ectoskeleton. The endoskeleton consists of all the internal bones and the ectoskeleton of a turtle is its shell. The endoskeleton is further divided into 2 subsections called the axial skeleton and the appendicular skeleton. The axial skeleton is made up of the skull and both the cervical and thoracic vertebrae. The appendicular skeleton on the other hand consists the remaining bones in the skeleton (Poland 2000).
