Question

Quizplus · Accepted Answer

Canaliculi are the small channels that radiate through the matrix of compact bone, connecting the lacunae (spaces where osteocytes are located) with each other and with the central canal (where blood vessels and nerves are found).

Answer: B 
 Lamellae are concentric layers of bone tissue that surround the central canal in an osteon (the basic unit of compact bone). They are composed of collagen fibers and mineral crystals, and provide strength and support to the bone.

Answer: E 
 Osteoclasts are large multinucleated cells that break down bone tissue, releasing calcium into the bloodstream. They are involved in bone remodeling and repair, and are particularly active in areas of bone that are under stress or strain.

Answer: A 
 Osteoblasts are bone-forming cells that deposit new bone tissue, particularly during bone growth and repair. They are located on the surface of bone and produce a protein matrix that eventually becomes mineralized, forming new bone tissue.

Answer: D 
 The medullary cavity is a hollow space in the center of long bones, such as the femur and the humerus. It contains yellow bone marrow (a fatty tissue that stores energy) and is surrounded by spongy bone and compact bone.
