Overview
Name the 5 functions of the skeletal system.
Support, Protection, Allow movement, Storage, Blood cell formation.
These cells are the bone builders of the body.
Osteoblasts
True or false: fractures and breaks are different
false
What sets of bones is the skull formed by?
The Cranium, and the facial bones
What are the two basic types of bone in the body?
Compact and spongy.
What do osteoclasts do?
Break down bone matrix and release calcium ions into the blood.
what is reduction?
Realignment of the broken bone ends.
Though it is not really part of the skull, this bone is closely related to the mandible and temporal bones.
The hyoid bone
In adults where is red marrow stored, and where is yellow marrow stored?
Red marrow: pelvis, sternum, ribs, vertebrae, and skull.
Yellow marrow: Long bones of the arms and legs
Bone remodeling is essential if bones are to retain what?
Normal proportions and strength during long bone growth as the body increases in size and weight.
A Greenstick fracture is most common in who?
Children
The lower teeth lie in the lower part of the mandible or also known as what?
The alveolar process
What does the periosteum do?
Protects the bone in a wrapping and helps with bone repair.
Except for flat bones, most bones develop using hyaline cartilage structures as their models. This process is called what?
Ossification
Name 3 types of factures
Comminuted, Compression, Depressed, Impacted, Spiral, Greenstick.
Name 3 bones in the cranium
Frontal bone, Parietal bones, Temporal bones, Occipital bones, Sphenoid bone, Ethmoid bone.
what do bone markings do?
Reveal where muscles, tendons, and ligaments attach and where blood vessels and nerves pass.
A disease in children which the bones fail to calcify.
Rickets
List the 4 major events involved in the repairing of a bone fracture.
A hematoma forms, A fibrocartilage callus forms, The bony callus forms, Bone remodeling occurs.
Name the facial bones of the body.
Maxillae, Palatine bones, Zygomatic bones, Lacrimal bones, Nasal bones, Vomer bone, Inferior nasal conchae, Mandible.
