Question 6

(Multiple Choice)

How are osteons in compact bone tissue aligned? How does the osteon arrangement affect bone strength?


A)horizontal to the metaphysis;the epiphyseal plate resists tearing due to the arrangement of osteons.
B)parallel to the epiphysis;the spongy bone follows the alignment of the osteons increasing the strength of the bone ends.
C)parallel to the length of the diaphysis;the shaft resists bending even when stresses are applied in certain directions.
D)randomly between the epiphyseal plates;the random arrangement of osteons makes the shaft strong no matter what direction the bone is stressed.
E)parallel to the perforating canals;the osteons running adjacent to the canals protects the vessels and nerves from becoming damaged.
