Analyze the question and options

The question asks which anatomical structure in adults contains yellow marrow, which consists mostly of fat.

Evaluate the anatomical structures

Using the Long Bone Anatomy knowledge point

• Articular cartilage: Hyaline cartilage covering the epiphyses at joints.
• Epiphysis: Using the Epiphysis knowledge point, this is the end of a long bone, which contains spongy bone filled with red bone marrow.
• Medullary cavity: The central hollow shaft (diaphysis) of a long bone. In adults, this cavity houses adipose tissue known as yellow bone marrow.
• Endosteum: Using the Endosteum Function knowledge point, this is the thin vascular membrane lining the inner medullary cavity.
• Periosteum: The fibrous membrane covering the outer surface of bones.

Select the correct option

The medullary cavity is the specific space that contains yellow marrow in adults.
