Q:

What are the two types of bone tissue?

A:

Quick Answer

The two types of bone tissue, also known as osseous tissue, are spongy and compact. Compact bone is dense, smooth and defines the exterior shapes of bones. Spongy bone has an asymmetrical, honeycomb-like structure that lines the longer bones and fills the bulky areas of bones.

Full Answer

Spongy bone, also known as cancellous bone, contains trabeculae, which are the open areas that contain red bone marrow. Compact bone is also known as cortical bone. Its primary structures are osteons, cylindrical layers of bone matrix that enclose and protect nerves and blood vessels.

The term "bone tissue" refers to the mineralized structure that makes up the immobile part of the bone. However, bones contain additional structures, such as blood vessels and nerves, which makes them organs.

    What is a corticated bone?

    A:

    Cortical bone is a dense and rigid layer of calcium-rich osseous tissue that makes up the outer layer of a bone, explains InnerBody. This compact bone layer is cylindrical in shape with a honeycombed structure, providing thousands of tiny canal-like passageways for nerves and blood vessels.

  • Q:

    What is compact bone tissue?

    A:

    One of the three layers of a bone, compact bone tissue is the rigid, dense outer layer of bone that consists primarily of calcium and minerals. Also called cortical bone, compact bones are so hard that a saw is needed to cut through it for surgery.

  • Q:

    How does the structure of a bone make it strong yet lightweight?

    A:

    The bone’s primary tissue, the osseous, is a hard, honeycombed, spongy composite material that is mainly formed of calcium phosphate, giving the bone its rigidity while remaining lightweight, according to the Better Health Channel. The porous osseous tissue is found between the bone marrow and the compact tissue.

    What are concentric lamellae?

    A:

    Concentric lamellae are the layers of compact bone tissue that make up the fundamental structure of cortical bones in most mammals. Lamellae, which translates to "little plates," are part of the Haversian system.
