Q

How many ossification centers does metatarsals, metacarpals and phalanges have?

A

Only have one 2 ossification center

17
Q

Certified radiology technologists

A

Certified individuals trained in radiology technology. Usually have a minimum of two years technical training/ Their primary responsibility is x-ray production. no diagnostic interpretation

18
Q

General Practitioners (MD, DC, DO, DPM, DDS)

A

primary professional degree individuals, whoa re granted by state statue the ability to utilize ionizing radiation for diagnostic purposes. Can provide X-ray production, and diagnose, also carry the liability for diagnostic interpretation

19
Q

Radiologists

A

Primary professional degree - same as a general practitioners - also have residency - produce X-ray, and primary purpose is to provide interpretation of diagnostic conclusion and carry liability - higher level of function than that of general practitioners

20
Q

Characteristics of the Cortex of bone

A

Calcium store

Major strength area

21
Q

The thickness of bone is (directly/inversely) proportional to the cortex?

A

Inversely - thinnest part of the bone - has the most cortex - thickest part of the bone - has the last amount of cortex

22
Q

Medullary cavity Characteristics

A

spongy, porous, houses bone marrow in axial skeleton of adults

23
Q

___% of bone metastasis is within the axial skeleton, because of red bone marrow.

A

90%

24
Q

Periosteum

A

External cortical surface

25
Q

Endosteum

A

internal cortical surface - where trabecular bone and cortex meet
