BONES & FUNCTIONS
This is the main function of the skeletal system that allows the body to maintain its shape.
What is support?
The tough outer layer of a bone is called this.
What is compact bone?
The place where two or more bones meet is called this.
What is a joint?
These cells build new bone tissue.
What are osteoblasts?
This is the longest bone in the human body.
What is the femur?
This mineral is stored in bones and is essential for muscle contraction and many body functions.
What is calcium?
The hollow space inside the shaft of a long bone is called this.
What is the medullary cavity?
This type of joint allows the greatest range of movement, such as the shoulder and hip.
What is a ball-and-socket joint?
These mature bone cells maintain existing bone tissue.
What are osteocytes?
This bone is located in the upper arm.
What is the humerus?
This type of bone protects the brain.
What are the bones of the skull?
This tissue is found at the ends of bones and helps reduce friction at joints.
What is cartilage?
The elbow is an example of this type of joint that primarily allows flexion and extension.
What is a hinge joint?
These cells break down and reabsorb bone tissue.
What are osteoclasts?
These two bones make up the lower leg.
What are the tibia and fibula?
This is the longest and strongest bone in the human body.
What is the femur?
This membrane covers the outside surface of a bone and contains blood vessels and nerves.
What is the periosteum?
These strong bands of connective tissue connect bone to bone.
What are ligaments?
The process of forming new bone tissue is called this.
What is ossification?
This bone is commonly called the kneecap.
What is the patella?
This part of the skeletal system includes the skull, vertebral column, and rib cage.
What is the axial skeleton?
This type of bone marrow is primarily responsible for producing red blood cells.
What is red bone marrow?
These structures connect skeletal muscle to bone and help produce movement.
What are tendons?
This process continuously removes old bone and replaces it with new bone tissue.
What is bone remodeling?
This bone forms the lower jaw and is the only freely movable bone of the skull.
What is the mandible?
