Skeletal Physiology Flashcards
which type of bone tissue is the strongest
cortical
What is the name given to the proximal and distal ends of a long bone
Epiphysis
Which division of the skeletal system is referred to as the ‘trunk’
Axial
Which measurement technique is used to assess 3D qualities of peripheral bones
PQCT
Proximal Quantitative Computed Tomography
Bone turnover is determined by the balance of ….
bone formation
bone resorption
Osteoclast are known as
Bone removing cells
During bone remodeling, which cell deposits bone minerals into the collagen scaffolding
Osteoblasts
What is the name given to the main body of a long bone
Diaphysis
What is the name of the process whereby hydroxyapatite crystals are deposited to increase bone stiffness
Calcification
Which athletes are most susceptible to developing osteoporosis
swimmers and cyclist
How is osteoporosis clinically diagnosed
BMD of 2.5 or more SD below the reference mean
why do siwmmers have the lowest BMD
Lack of weight bearing element
Osteoblasts are known as

Which component of bone is responsible for the production of RBC
RED MARROW
On average, what proportion of the bone matrix is organic material
40%
Which division of the skeletal system involves the upper and lower extremities
Appendicular
Which measurement of bone does DXA scan provide
Bone Mineral Density
What is the primary mineral that is stored and released from bone
Calcium
According to Varley et al., (2018), at which point during a competitive season was the bone mineral content of elite speed skaters lowest
Mid-Season
What does osteoporosis increase the risk of
Fragility fractures
According to Frost (1990), which is the ‘minimal effective strain’ that produces bone growth?
Overload
Which joint has the greatest amount of movement
Synovial
In the study by Varley et al., (2018), the change in bone mineral content over the season was different between legs
One leg received more loading due to the characteristics of the sport
what is the main component of the organic matrix in bone
Collagen
