perpendicular plate of the ethmoid and vomer bones

the sacrum is composed of... fused bones

5 fused bones

the portion of the sternum the articulates with the clavicle is the

manubrium

the bony compartment that houses the brain is called the

unusual distortion of the skull that occur from the premature closure of one or more fontanels is

craniostenosis

the first cervical vertebrae is also known as

atlas

the second cervical vertebra is also known as the

axis

true ribs are directly connected to the sternum by

costal cartilage

ribs that have no connection to the sternum are called...

floating ribs

ribs 8-12 are called....because they do not attach directly to the sternum

false ribs

lumbago

a physician (M.D) who specializes in the structure and function of bones is called

orthopedist

training that is similar to M.D.'s but generally place more emphasis on musculoskeletal functions
