Bone Basics
This part of the skeleton includes the skull, vertebral column, and rib cage.
What is the axial skeleton?
The shaft of a long bone is known as this.
What is the diaphysis?
These bones are longer than they are wide and act as levers.
What are long bones?
A fracture that does not break the skin.
What is a closed fracture?
These cells build new bone tissue.
What are osteoblasts?
This part of the skeleton includes the limbs and girdles.
What is the appendicular skeleton?
The end of a long bone is known as this.
What is the epiphysis?
These bones are cube-shaped and found in wrists and ankles.
What are short bones?
A fracture where the bone breaks through the skin.
What is an open fracture?
These cells break down and reabsorb bone tissue.
What are osteoclasts?
The process of forming new blood cells occurs in the bone marrow and is called this.
What is hematopoiesis?
The membrane that covers the outer surface of bones is called this.
What is the periosteum?
These bones are thin and often provide protection, like the skull or ribs.
What are flat bones?
A fracture where the bone bends, common in children.
What is a greenstick fracture?
Bone tissue that is dense and makes up the outer layer of bones.
What is compact bone?
A small pit or depression on a bone that often receives another structure is called this.
What is a fossa?
The space inside a long bone that contains yellow marrow.
What is the medullary cavity?
These bones have complex shapes, like the vertebrae or pelvis.
What are irregular bones?
A fracture where the bone is crushed under pressure.
What is a compression fracture?
Bone tissue that has a porous, honeycomb structure, found in the ends of long bones.
What is spongy bone?
A shallow groove on a bone surface is called this.
What is a sulcus?
This structure between the epiphysis and diaphysis allows bone to grow in length.
What is the epiphyseal plate?
The rounded end of a bone that forms part of a joint is called this.
What is the head?
A fracture where a fragment of bone is pulled away by a tendon or ligament.
What is an avulsion fracture?
A disease that causes bones to become weak and brittle due to loss of bone density.
What is osteoporosis?
