Appendicular skeleton - bones of extermities
Which of the following is classified as long bones?
A. Metacarpals
B. Scapulae
C. Coxa
D. Carpal bone
A. Metacarpals
Forms the shaft and is composed of compact bone that encloses the marrow cavity
A. Diaphysis
B. Epiphysis
C. Metaphysis
D. Syndesmoses
A. Diaphysis
Expanded articular ends, separated from the shaft by a plate during bone growth; composed of spongy bone
A. Diaphysis
B. Epiphysis
C. Metaphysis
D. Syndesmoses
B. Epiphysis
Consists of two layers of compact bone enclosing spongy bone and marrow space
A. Long bone
B. Short bone
C. Sesamoid bone
D. Flat bone
D. Flat bones
These are commonly found where tendons cross the ends of long bones in the limbs, as in the wrist and the knee
A. Short bone
B. Irregular bone
C. Sesamoid bone
D. Flat bone
C. Sesamoid bone
- develop in certain tendons, reducing friction and thus protecting it from excessive wear
Have articular surfaces that are covered with fibrocartilage and grow by replacement of connective tissue
A. Long bones
B. Flat bones
C. Irregular bones
D. Short bones
B. Flat bones
Cells that synthesizes new bone
osteoblast
osteoBlast - bumubuo ; osteoClast - kumakalas
Hormone responsible for the mobilization of calcium for bone resorption
PTH
“P” = promotion
Hormone responsible for the suppression of calcium mobilization
Calcitonin
“C” = cease
It is a gradual softening of the bone due to failure of the bone to calcify due to vitamin D deficiency or renal tubular dysfunction
A. Osteopenia
B. Osteomalacia
C. Osteoporosis
D. Osteopetrosis
B. Osteomalacia
A bone disorder characterized by a decrease in bone calcification or reduced bone mass due to an inadequate osteoid synthesis
A. Osteopenia
B. Osteomalacia
C. Osteoporosis
D. Osteopetrosis
A. Osteopenia
A bone disorder characterized by decreased bone mass and increased susceptibility to fracture of the hip, vertebra, and wrist, and commonly in elderly
A. Osteopenia
B. Osteomalacia
C. Osteoporosis
D. Osteopetrosis
C. Osteoporosis
Bone disorder characterized by an abnormally dense bone, obliterating the marrow cavity, due to defective resorption of immature bones
A. Osteopenia
B. Osteomalacia
C. Osteoporosis
D. Osteopetrosis
D. Osteopetrosis
The following are true of the primary cartilaginous joints except:
A. Permit little to no movement
B. united by fibrocartilage
C. synchondroses
D. epiphyseal plate
B. United by fibrocartilage
- Cartilaginous joints
- synchondroses
- little to no movement
- allow for growth in length
- epiphyseal plate, sphenooccipital, manubriosternal
