- The structure of the skeletal system
- Functions: The skeletal system has five particular functions which are linked directly to it's structure
- SHAPE for maintaining our basic body shape
- SUPPORT for muscles and vital organs
- PROTECTION, such as the skull protecting the brain
- MOVEMENT at joints
- BLOOD-CELL PRODUCTION in the bone marrow
- Joints: The skeletal system can only allow movement to happen when it is joined up by the muscular system. All movement occurs at joints, which fall into these categories
- BALL AND SOCKET such as the hip and shoulder
- HINGE such as the elbow and the knee
- PIVOT such as the wrist
- GLIDING such as the bones in the hand
- CANDYLOID such as the wrist
- SADDLE such as the thumb
- Connective Tissue: Connective tissue links the bone to muscles, there are three types of connective tissue
- LIGAMENTS are bands of fibre attached to the bones that link the joints. They help keep the joints stable
- CARTILAGE is a tough but flexible tissue that acts as a buffer between the bones and the joints. This can be seen at the ends of the femur and tibia.
- TENDONS are very strong, non elastic cords that join the muscles to the bone. They can be seen joining the quadriceps muscle to the patella
- Bones: The skeletal system is made up of bones, these fall into the following four categories
- FLAT (OR PLATE) BONES such as the skull
- LONG BONES such as the femur
- IRREGULAR BONES such as the vertebrae
- SHORT BONES such as the carpels and tarsals
- Functions: The skeletal system has five particular functions which are linked directly to it's structure
