Functions & Bone Structure
This bone type is longer than it is wide and is found in arms and legs.
What is a long bone?
This tough band of tissue connects bone to bone.
What is a ligament?
These bones form the central axis of the skeleton and include the skull and spine.
What is the axial skeleton?
This type of fracture does not break the skin.
What is a simple or closed fracture?
This cartilage plate allows long bones to grow in length during development.
What is the epiphyseal plate?
This layer covers the bone and contains blood vessels, nerves, and bone-rebuilding cells.
What is the periosteum?
This type of cartilage remains flexible and grows throughout life, such as in the nose and ears.
What is permanent cartilage?
This part of the sternum is the most inferior and can break off during improper CPR.
What is the xiphoid process?
This fracture type spirals around the bone due to a twisting force.
What is a spiral fracture?
This process describes the natural cycle of tearing down and rebuilding bone.
What is bone remodeling?
These cells are responsible for building new bone tissue.
What are osteoblasts?
This joint type allows movement in multiple directions and is found in hips and shoulders.
What is a ball-and-socket joint?
This spinal condition causes a forward curvature of the thoracic spine.
What is kyphosis?
This incomplete fracture is more common in children due to pliable bones.
What is a greenstick fracture?
These bone cells break down bone during the resorption phase.
What are osteoclasts?
This part of the bone is hollow and stores bone marrow.
What is the medullary cavity?
This sac contains synovial fluid and can become inflamed in bursitis.
What is a bursa?
This condition results from progressive cartilage loss and bony buildup in joints.
What is osteoarthritis?
This fracture results in the bone being crushed into several pieces.
What is a comminuted fracture?
This stage of bone healing involves the formation of a soft cartilaginous bridge.
What is soft callus formation?
This process involves replacing cartilage with bone and continues into a person's 20s.
What is endochondral ossification?
This movement describes turning the sole of the foot inward.
What is inversion?
This condition is caused by more bone being broken down than built, leading to brittle bones.
What is osteoporosis?
This medical procedure aligns broken bone ends before immobilization.
What is reduction?
This hormone-regulated process recycles calcium and phosphate to maintain balance.
What is bone resorption?
