What are the two main functions of flat bones?
They contain bone marrow, where red blood cells are made.
They protect internal organs.
They provide an area for muscle attachment.
They connect bones such as the patella and tibia.

An example of a long bone is the scapula. True or false?
True
False
Describe the characteristics of irregular bones and give an example.
Irregular bones are flat and protect organs; example: ribs.
Irregular bones are long and cylindrical; example: tibia.
Irregular bones have complex shapes and provide support; example: vertebrae.
Irregular bones are cube-shaped and provide stability; example: tarsals.
The skeletal system has five main functions.
It gives the framework to which the soft tissues attach, and gives the body its shape.
It helps with movement. The bones are the levers upon which our muscles pull.
It protects vital organs; for example, the skull protects the brain, and the ribs protect the heart and lungs.
It is the site of blood cell formation. The long bones contain bone marrow, which produces all of our red blood cells and some white blood cells.
It stores mineral salts, especially calcium. Degradation of bones and joints can lead to diseases and abnormalities such as osteoarthritis and osteoporosis.
Short bones, They are roughly cubical; that is, they have the same width and length (e.g. the carpal bones of the wrist and the tarsal bones of the foot).
Long bones, They are longer than they are wide and have a hollow shaft containing marrow (e.g. the femur, phalanges and humerus).
Flat bones, They provide flat areas for attachment of muscles and usually enclose cavities to protect organs (e.g. the scapula, ribs, sternum and skull).
Irregular bones, have no regular shape characteristics (e.g. the vertebrae and bones of the face).
Sesamoid bones, They are small bones developed in tendons around some joints (e.g. the patella at the knee joint).
Each vertebra has a hollow centre through which the spinal cord travels. In this way, the cord is protected.
As the vertebrae descend from the cervical to the lumbar region, they increase in size. This helps them to support the weight of the upper body.
Movement between two vertebrae is very limited. But the range of movement of the vertebral column as a whole unit is great, allowing bending, twisting and rotation. Use the Vertebral column worksheet in your Online Resources to label the sections of the vertebral column.
What are the five main functions of the skeletal system?
Describe the role of bone marrow in the skeletal system.
The skull protects the (a) .
Long bones have a hollow shaft containing (a) .
The patella is an example of a (a) bone.
Cartilage is a smooth, slightly elastic tissue. It is found in various forms in the body. The ends of the bones in synovial joints are coated with smooth, shiny cartilage called hyaline cartilage. Some synovial joints also have cartilage between the bones (e.g. the knee). The vertebrae of the spine are separated by discs of cartilage, and the ribs attach to the sternum by way of cartilage. The cartilage in the knee and between the vertebrae provides shock absorption during movement. The hard part of the ear and the tip of the nose are also cartilage.
What is cartilage and where is it found in the body?
Explain the role of cartilage in synovial joints.
How does cartilage contribute to shock absorption in the body?
The ends of the bones in synovial joints are coated with smooth, shiny cartilage called (a) cartilage.
The vertebrae of the spine are separated by discs of (a) , which provide shock absorption during movement.
