Long: Long bones provide strength and structure. They are hard and dense. The Femur and Tibia are examples of long bones. A long bone has a shaft, known as the diaphysis and two expanded ends known as the epiphysis.
Short: Short bones are made to provide support and stability with limited movement. They are described as small, and light. They are stronger than long bones. Short bones have a thin layer of compact bone, and are mostly filled with spongy bone. Short bones are described to be as wide as they are long. Examples of short bones include the bones in the wrist and ankle.
Flat: Flat bones are thin, flattened and slightly curved. They are made up of a layer of spongy bone between two thin layers of compact bone. They have a large surface area. Examples include the skull and ribs. Flat bones have marrow, but not a bone marrow cavity.
Irregular: These are bones in the body which do not fall into any other category, due to their non-uniform shape. Irregular bones

These are essential for bone growth and the maintenance of bone health. These minerals are released into the bloodstream from the bones and they ensure you have the correct balance of minerals in your body.
Types of joints
Fixed: Fixed joints do not move, they interlock and overlap. They are held together by bands of tough fibrous tissue and are very strongly bound together. These types of joints are crucial for protection and stability. An example of this is between the plates in your cranium.
Cartilaginous: these joints allow little movement. The ends of the bones are covered in articular or hyaline cartilage. This is a smooth, shiny covering that reduces friction, it is separated by pads of absorbent tough cartilage called fibrocartilage. Little movement at the surface is possible because the pads of cartilage compress. An example of this is between the
