Study Guide 2
| Term | Definition |
|---|---|
| Type of cell responsible for bone growth & thickening, ossification, and regeneration | Osteoblast |
| Does Periosteum enclose all of the bone & joint surfaces & provide a blood supply to underlying bone? | No, only covers the diaphysis |
| The human body normally contains how many bones total? Appendicular? Axial? | 206. 126. 80 |
| Portion of long bone considered the primary site of ossification | Diaphysis |
| Congenital Club Foot is also known as | Talipes Equinovarus deformity |
| Increase in bone density (but still brittle) often referred to as marble, chalk or ivory bones is called | Osteopetrosis |
| Most common site where metastatic cancer are? Breast? Lung? Brain? | Breast and Lung (as well as kidneys, Prostate, thyroid, bowel) |
| Brittle Bone disease is also referred to as? | Osteogenesis imperfecta (can lead to dwarfism) |
| Lesions shorter than 10 cm are characteristic of what type of bone cancer | Secondary (present because of primary lesion). Primary are 10cm+ (4.5") |
| A solitary lesion is characteristic of what type of bone cancer | Primary |
| Evidence of soft tissue masses are characteristic of what type of bone cancer | Primary |
| The bony structure most commonly encountering metastases from primary neoplasms | vertebral column |
| Formation of extra digits | polydactyly |
| Modality of choice for demonstrating vertebral fractures or other bony anomalies | CT |
| The type of arthritis that is triggered when an immunogenetically susceptible host is exposed to an arthritogenic antigen is | Rheumatoid |
| Projection of the spine that will decrease dose to the breasts and thyroid | PA |
| 80% of all scolioses are | iopathic |
| Congenital abnormality in which the brain and cranial vault do not develop | Anencephaly |
| Osteogenesis imperfecta tarda is present at birth? | False. Osteogenesis imperfecta congenital is present at birth |
| Most commonly inherited disorder affecting the skeletal system is | Achondroplasia (form of dwarfism) |
| Neoplastic disease that has the radiographic appearance of a soap bubble | Giant Cell Tumor (GCT) |
| Spina Bifida is the result of | Failure of Laminae to unite and/or Failure of spinous process to form |
| Imaging modality that plays a key role in primary diagnosis of neoplasms of the skeletal system | CT |
| Osteomas are most commonly found on the | Skull. They are benign but can compress the brain affecting vision, etc if large |
| The malignant bone neoplasm usually occurring in pediatric patients & arise from the medullary canal that eventually leads to uniform thickening of the bone | Ewing's Syndrome |
| Benign bone lesion usually affecting the long bones of men | Osteochondroma (Exostosis) |
| Genetic disorder of connective tissue commonly seen in above average height people & can affect the heart and aorta (cardiovascular system) | Marfan's Syndrome |
| Osteogenesis imperfecta requires what type of technical factor change | Decrease. "Brittle Bone" |
| Osteoarthritis requires what type of technical factor change | Decrease. Hylin cartilage wears away |
| Osteosarcoma requires what type of technical factor change | Increase. Because of increase in osteoblasts in that area |
| Osteochondroma requires what type of technical factor change | Increase. Though benign, there is an increase in bone growth |
| Osteopetrosis requires what type of technical factor change | Increase. "Marble Bone" |
| Arthritis caused by streptococci, staphylococci, or gonococci | Acute |
| Arthritis generally occurring between the ages of 30-40 that is typically genetic | Rheumatoid |
| Arthritis that may include clinical symptoms of pain & swelling of the joint | Rheumatoid and Acute |
