Question

Quizplus · Accepted Answer

The periosteum is a connective tissue layer that covers the outside of bones, providing structural support and protection.

Answer: C
 The periosteum does not typically form chondrocytes (cartilage cells), but rather contains osteoblasts (bone-forming cells) which aid in bone growth and development.

Answer: D
 The inner lining of the bone, including the medullary cavity (the hollow center of long bones filled with bone marrow), is known as the endosteum.

Answer: E
 While the periosteum does contain blood vessels that help to nourish bone tissue, the primary role of blood cell formation (hematopoiesis) occurs within the bone marrow, not the periosteum.
