Verified step by step guidance
1
Understand the structure of long bones: Long bones consist of several parts, including the diaphysis, epiphysis, and medullary cavity.
Define compact bone: Compact bone is dense and forms the outer layer of bones, providing strength and support.
Identify the location of compact bone: Compact bone is primarily found in the diaphysis, which is the shaft or central part of long bones.
Differentiate between compact and spongy bone: Spongy bone, also known as cancellous bone, is found in the epiphysis and contains trabeculae, which are less dense than compact bone.
Recognize the function of compact bone: It provides structural support and protection, and is crucial for the weight-bearing capacity of long bones.
