Chp 3 Skeletal System

cells that make new bone then they turn into

˜the mature cells in bone

they are responsible for breaking down bone

forms outer covering of all bones

Has spaces called Trabeculae that are filled marrow

• function of the osteoblast
• The response to forces (muscle and fibers) pulling on bone – resulting in formation of new bone

• Function of the Osteoclasts
• The response to pressure on the bone, or little or no activity against the surface of the bone – resulting in the destruction of bone

braces pull and compress the periodontal ligament resulting in bone deposition and resorption

• eight cranial bones
• twelve facial bones
• and the paired palatine bones

cranium/ facial bones

• Occipital bone
• Frontal bone
• Sphenoid bone
• Ethmoid bone
• 2 parietal bones
• 2 temporal bones

The mucous membranes of the sinuses can become inflamed and congested with mucus

the inflammation of the sinuses from another source such as an infection of the adjacent teeth

an abnormal hole formed in the wall of the sinus due to the inflammatory process, also can occur with infection

any prominence on a bony surface

A narrow cleft-like opening in a bone

a short window-like opening(s) in a bone

• vomer
• mandible 
• lacrimal bones
• nasal bones
• inferior nasal conchae
• zygomatic bones
• maxillae

lacrimal bones

A generally deeper depression(s) or concavity on a bony surface

small horn-like prominence on a bony surface

An oval prominence usually involved in joints

a small prominence located superior to or upon a condyle

small rounded elevation on a bony surface
