Question

Quizplus · Accepted Answer

The central (Haversian) canal in each osteon contains blood vessels and nerve fibers, which provide nourishment and communication throughout the bone tissue. Option A (adipose tissue) is incorrect because adipose tissue is not found in the central canal of osteons. Option C (yellow marrow and spicules) is incorrect because yellow marrow is found in the medullary cavity of long bones, not in the central canal of osteons. Option D (cartilage and interstitial lamellae) is incorrect because cartilage is not found in the central canal of osteons, and interstitial lamellae are located between osteons, not within the central canal of individual osteons.
