A
In the epiphysis of long bones
B
In the medullary cavity of long bones
C
In the periosteum of bones
D
In the spongy bone of flat bones
Verified step by step guidance1
Understand the structure of long bones: Long bones have a central shaft called the diaphysis and two ends called epiphyses. The diaphysis contains a hollow region known as the medullary cavity.
Learn about bone marrow types: There are two types of bone marrow - red and yellow. Red bone marrow is involved in blood cell production, while yellow bone marrow primarily stores fat.
Identify the location of yellow bone marrow: Yellow bone marrow is typically found in the medullary cavity of long bones. This cavity is located in the diaphysis, or the central shaft, of the bone.
Differentiate between bone structures: The epiphysis of long bones contains spongy bone, which may have red bone marrow, especially in children. The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.
Conclude the typical location: Based on the understanding of bone anatomy and marrow types, yellow bone marrow is typically found in the medullary cavity of long bones, not in the epiphysis, periosteum, or spongy bone of flat bones.
