What is the structure of the skeletal system?
The skeletal system is made up of two parts, the first is the Axial skeleton and the second is the appendicular skeleton. The Axial skeleton is found in the core of the body, these bones are in place to protect the vital organs. Starting from the head there are 29 bones in the head. There is 8 cranial bones and 14 facial bones. There are 7 bones in the head are associated bones. Then working down there is 25 bones of the thorax which is found in the sternum, these are more commonly known as our ribs. The ribs protect the organs in the centre of your body such as your lungs, liver and heart. Then finally there are 26 bones in your vertebral column, these are the bones that run down your back including the sacrum and the coccyx.

The appendicular part of the skeletal system supports the appendages of vertebrates. The appendicular skeleton includes the arms, hands legs, the shoulder girdle and pelvic girdle. Of the 206 bones in the human body 126 of these make up the appendicular skeleton. Due to the appendicular bones being found in the hands, arms and legs they allow more movement than possible with the axial skeleton found at the core.

Types of bones:
Long bones are some of not only the longest bones but also the shortest bones in the body, the longer bones include; the femur, humorous and tibia. Then the small bones include; the metacarpals, metatarsals and phalanges. To be called a long bone it must have a body which is

The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions; support, movement, protection, blood cell production, calcium storage and endocrine regulation that enable us to survive. Below are more details on the exact role the skeletal system has on; protection, shape, support, movement and blood production:
