General Skeleton
Part of the skeleton that contains the skull, spine and ribcage
A substance that fills the inside cavity of a bone which makes blood cells.
A unit of bone containing a central canal and matrix rings
What is an osteon?
What bones start as in early development
Hyaline cartilage
(except flat bones start as membranes)
Difference between open and closed fractures
What is open the bone goes through the skin, closed the bone does not go through the skin.
Bones that are longer than they are wide
What is long bones
The line in the middle of the spongy bone in the ends of a bone.
What is the epiphyseal line?
The purpose of a central canal
What is it carries blood vessels and nerves
The cells that build new bone during development and remodeling
Common fractures in small children.
What are greenstick fractures.
This category involves the pelvis and vertebra
What is irregular bone
The hollowed out area that can be filled with two types of bone marrow
What is the medullary cavity?
Lamella
What is a ring of osseous tissue in compact bone.
The purpose of the epiphyseal plate and what it is made of.
What is to provide a place for new bone growth to lengthen bones during childhood growth. What is cartilage.
Hematoma
What is a blood-filled swelling, the first step after a bone breaks.
List the parts of the skeleton that are part of the appendicular skeleton.
What are arms, legs, pelvis and shoulder blades/collar bones.
The two coverings that surround the bone - one is on the long part and one is on the ends
What are:
Articular cartilage - on the ends
Periosteum - on the long part
Canaliculi
Three locations of bone growth around or in a long bone during development.
What are: around the diaphysis, in the middle of the diaphysis and in the centers of the epiphysis.
The type of bone in a bony callus
What is spongy bone
The functions of the skeletal system.
What are:
Support the body
Protect soft organs
Allow movement due to attached skeletal muscles
Store minerals and fats
Blood cell formation
Where is red bone marrow found, in adults and children.
What is spongy bone in adults and children (in the ends of bones, in the flat bones)
In children also found in the medullary cavities.
A perforating canal
What is
Canal perpendicular to the central canal
Carries blood vessels and nerves
Purposes of bone remodeling in adults.
What is to maintain homeostasis of calcium levels in the blood and in response to the pull of gravity and muscles on the skeleton.
What replaces a hematoma in fracture healing and what is in it.
What is fibrocartilage callus containing new capillaries, connective tissue - cartilage, spongy bone, fibrous collagen
