- it serves as framework for the body
- the skeleton provides mechanical protection for many of the body's internal organs
- bone tissues store several minerals
- the red bone marrow inside some larger bones blood cells are produced
- Long bones- have greater length than width and consist of a shaft and a variable number of endings
- Short bones- are roughly cube-shaped and have approximately equal length and width
- Flat bones- have a thin shape/structure and provide considerable mechanical protection and extensive surfaces for muscle attachments
- Irregular bones- their shapes are due to the functions they fulfill within the body e.g. providing major mechanical support for the body yet also protecting the spinal cord
- Compact- tissue forms the outer shell of bones. It consists of a very hard (virtually solid) mass of bony tissue arranged in concentric layers (Haversian systems)
- Spongy- tissue is located beneath the compact bone and consists of a meshwork of bony bars (trabeculae) with many interconnecting spaces containing bone marrow.
