Gross Anatomy of Bone: Periosteum and Endosteum
Multiple Choice
Which of the following is true of the periosteum?
A
It is primarily responsible for the production of red blood cells.
B
It lines the inner surface of the bone, including the medullary cavity.
C
It is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.
D
It is a thin layer of cartilage covering the ends of long bones.
Verified step by step guidance1
Understand the function and location of the periosteum: The periosteum is a dense layer of vascular connective tissue that covers the outer surface of bones, except at the joints where articular cartilage is present.
Differentiate between the periosteum and other bone-related structures: The periosteum should not be confused with the endosteum, which lines the inner surface of the bone, including the medullary cavity.
Recognize the role of the periosteum in bone health: It plays a crucial role in nourishing bone tissue and providing a surface for the attachment of tendons and ligaments.
Identify the incorrect statements: The periosteum is not responsible for the production of red blood cells; this function is primarily associated with the bone marrow.
Clarify the misconception about cartilage: The periosteum is not a layer of cartilage; it is a connective tissue layer, whereas cartilage covers the ends of long bones at the joints.
