Choose the structures that most directly provide nutrients and remove wastes from osteocytes in compact bone.
A) perforating (Volkmann's) canals
B) central canals
C) nutrient foramens
D) canaliculi

Question

Quizplus · Accepted Answer

Canaliculi are tiny channels that extend from the lacunae of the osteocytes to nearby blood vessels and the central canal. They are responsible for exchanging nutrients and wastes between the osteocytes and the blood vessels. Perforating canals (A) provide a pathway for blood vessels to enter and exit the bone, but they do not directly interact with the osteocytes. Central canals (B) are also involved in blood vessel transport, but they are found only in cancellous bone, not compact bone. Nutrient foramens (C) are openings in the bone that allow blood vessels and nerves to enter and exit, but they are also not directly involved in nutrient/waste exchange with osteocytes.
