Which of the following statements is true?
mr Goodwill [35]

Answer:

Spongy bone is well adapted to accept stress in many directions, which makes it good for shock absorption

Explanation:

Spongy bone tissue is less compact and always present towards the interior of the bone and is covered by compact bone. Spongy bone tissue has lamellae that are arranged in an irregular pattern. The thin irregular columns of lamellae are called trabeculae.

The trabeculae of spongy bone tissues are precisely arranged along the line of stress. This feature of spongy bones allows them to resist the stress applied from many directions and to transfer the force making them a good shock absorber. The final arrangement of trabeculae is achieved only after the person learns the locomotory movements completely.
