The strongest layer of bone is the outer bone layer (compacta).
Understanding Bone Structure and Strength
Bones aren't solid; they have different layers that contribute to their overall strength and function. Here's a breakdown:
- Outer Bone Layer (Compacta): According to the provided reference, this is the hard and strong outer wall of the bone. It's designed to withstand significant stress.
- Inner Bone Structure: Inside the compacta is a supporting structure of interconnecting bony plates and rods called trabeculae. While crucial for support and housing bone marrow, it isn't as strong as the compact bone.
Why Compact Bone is Stronger
Compact bone's strength comes from its dense structure. The tightly packed arrangement of mineralized tissue makes it highly resistant to bending and compression forces.
