Where is plexiform bone found?

Water buffalo long bone cortical bone contains both plexiform and Haversian bone tissue (11,17). Plexiform bone is located near the periosteal surface and anterior in the bone, while Haversian bone is located toward the endosteal surface and posterior in the bone (17).

Where is trabecular bone found?

Trabecular bone is a highly porous, heterogeneous, and anisotropic material which can be found at the epiphyses of long bones and in the vertebral bodies.

What is the difference between cancellous and cortical bone?

A Cortical and Cancellous Bone Cortical bone is a dense tissue that contains less than 10% soft tissue. Cancellous or spongy bone is made up of trabecules shaped as plates or rods interspersed between bone marrow that represents more than 75% of the cancellous bone volume.

What is trabecular bone and cortical bone?

Trabecular bone has a large surface exposed to the bone marrow and blood flow, and the turnover is higher than in cortical bone [1]. Resorption takes place along bone surfaces in the trabecular bone, whereas in the cortical bone, resorption tunnels through the bone itself.

What is inside the haversian Canal?

Haversian canals are microscopic tubes or tunnels in cortical bone that house nerve fibers and a few capillaries. This allows bone to get oxygen and nutrition without being highly vascular. These canals also communicate with bone cells using special connections, or canaliculi.

Is lacuna a cell?

osteocyte, a cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna, which is contained in the calcified matrix of bone. Osteocytes derive from osteoblasts, or bone-forming cells, and are essentially osteoblasts surrounded by the products they secreted.

Is trabecular bone soft?

Spongy bone is softer and weaker than compact bone, but is also more flexible. It is characterized by a lattice-like matrix network called trabeculae (Latin for little beam) that gives it its spongy appearance. The figure below illustrates spongy bone.

What trabecular bone means?

cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called trabeculae, arranged along lines of stress.

What are cancellous bones?

Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.

Why is spongy bone called cancellous?

Cancellous bone is also known as spongy bone because it resembles a sponge or honeycomb, with many open spaces connected by flat planes of bone known as trabeculae. Inside the trabeculae are three types of bone cells: osteoblasts, osteocytes and osteoclasts. Osteoblasts are the cells that make new bone.

What is diaphysis bone?

The diaphyses (singular: diaphysis), sometimes colloquially called the shafts, are the main portions of a long bone (a bone that is longer than it is wide) and provide most of their length.
