Functions of the Skeleton
This function of the skeleton involves providing a framework for the body and maintains its shape.
What is support?
This part of the skeleton includes the skull, vertebral column, and rib cage
What is the axial skeleton?
This is the shaft of a long bone.
What is the diaphysis?
These joints are immovable and found in the skull
What are fixed (immovable) joints?
This movement decreases the angle between two bones.
What is flexion?
The skeleton has vital organs such as the brain, heart, and lungs. Name the function that looks after these.
What is protection?
This part of the skeleton includes the limbs and shoulder/hip girdles.
What is the appendicular skeleton?
This part of a long bone is covered with articular cartilage and forms a joint with another bone.
What is the epiphysis?
These joints allow for slight movement and are found between vertebrae.
What are slightly movable (cartilaginous) joints?
This movement increases the angle between two bones
What is extension?
This function involves blood cells within the bone marrow.
What is blood cell production
This bone is also known as the collar bone
What is the clavicle?
This cavity within the diaphysis contains yellow marrow.
What is the marrow cavity?
These joints are freely movable and include the shoulder and hip joints.
What are freely movable (synovial) joints?
This movement moves a limb away from the midline of the body.
What is abduction?
The skeleton contains calcium and phosphorus. Name this function
What is mineral storage?
These bones make up the spine and include cervical, thoracic, and lumbar regions
What are vertebrae?
This dense outer layer of bone provides strength and protection
What is compact bone?
This fluid-filled space reduces friction between the bones in a synovial joint.
What is the synovial fluid?
This movement moves a limb toward the midline of the body
What is adduction?
This function allows is assisted by providing attachment points for muscles
What is movement?
This bone is the largest and strongest bone in the human body
What is the femur?
This type of bone tissue is found at the ends of long bones and contains red marrow.
What is spongy bone?
This structure surrounds and protects a synovial joint
What is the articular capsule?
These muscles work in pairs to produce opposite movements, such as the biceps and triceps.
What are antagonistic muscles?
