| Question | Answer |
| Support and Protection | Support:Bones provide a framework for the attachment of muscles and other tissues. Protection: Bones such as the skull and rib cage protect internal organs from injury. |
| Hematopoiesis | blood cell formation in red bone marrow; found primarily in spongy bone of the skull, ribs, sternum, clavicles, vertebrae, and pelvis. |
| Inorganic Salt Storage | salts account for about 70% of matrix by weight; most are crystals of calcium phosphate called hydroxyapatite. |
| Storage of Lipids | Lipids, such as fats, stored in adipose cells of the yellow marrow serve as an energy reservoir. |
| Movement | Bones enable body movements by acting as levers and points of attachment for muscles. |
| Shape | Bone structure gives shape to the body. This shape changes as you grow, and your skeletal system determines your height, width and determines the body shape eg tall and thin, mesomorphs,shorter and muscular,apple or pear-shaped. |
| Blood cell reproduction and storage in long bones. | The spongy tissue inside long bones, have two types of marrow responsible for blood cell production.Red bone marrow gives rise to blood cells while yellow bone marrow stores fat, which turns into red bone marrow in case of severe red blood cell depletion or anemia. |
| Protection of Organs | The cranium bone --skull -- houses the brain, while the vertebral, or spinal, column protects the delicate spinal cord, which controls all bodily functions through communication with your brain. The bony thorax, comprised of the ribs and sternum, protects your heart and lungs. |
| Musculoskeletal system | The skeletal bones are held together by ligaments. Tendons attach your muscles to the bones of your skeleton. The muscular and skeletal systems work together to carry out bodily movement, and together they are called the musculoskeletal system. |
| Example: Support | The vertebral column allows you to stand erect, while cavities -- hollow spaces in the skeleton are designed to hold your organs. For example, the skull holds the brain, the chest cavity holds your lungs and heart while the abdominal cavity holds your gastrointestinal organs. The pelvis and leg bones are strong and thick to support the weight of the entire skeleton. |
