Osseous tissue refers to the hard mineral portion of bones. Compact bone and spongy bone are two types of osseous tissue that can be found in any bone in the body. The key differences between the two types are how the bone mineral is organized and how much free space there is between the solidified extracellular matrix. Spongy bone is made up of a web-like structure of solidified extracelluar matrix, whereas compact bone appears solid.
Although compact bone appears to be sturdy and uninterrupted at first sight, closer analysis shows that osseous tissue only accounts for 70-95 percent of the total volume. Also in compact bone, pores and gaps exist. Compact bone’s osseous tissue is structured in cylindrical osteons except at its edge. Each osteon is a concentric cylinder of lamellae. The osteocytes that line the edges of each lamella are the only cells in an osteon. Lacunae, which are cell-shaped empty spaces that prevent the solid, mineralized extracellular material of bone from crushing the osteocytes, are where osteocytes can be located. Cytoplasmic extensions protrude from each osteocyte and are housed in canaliculi, thin empty channels that protect the osteocyte extensions from being crushed by solid, mineralized extracellular material. A central canal (also known as a Haversian canal) runs through the middle of each osteon, allowing blood vessels, lymph vessels, and nerves to service and signal the cells in the compact bone. Perforating canals (also known as Volkmann’s canals) are empty spaces at the base of individual osteons that allow blood vessels, lymph vessels, and nerves to pass through bone and communicate with vessels and nerves in the central canals. Cortical bone is another name for compact bone.

When ligaments are overstretched or ruptured (torn), the spine can move out of line or vertebrae can ‘lock’ over each other, causing spinal dislocation. A spinal cord injury may also occur as a result of this. A dislocation is typically treated with traction or surgery to realign the vertebrae during a procedure known as “reduction.” You may also require spinal fusion surgery to connect the vertebrae and keep them in the proper alignment.
A subluxation, also known as a partial dislocation, occurs when the back joints of the vertebrae become weak, typically as a result of an injury to the muscles or ligaments in the spine, causing the bones to shift abnormally. It can cause damage to the spinal cord in some cases, necessitating spinal fusion to stabilize it.

Do you recognize the food object in the photo’s upper left corner? It’s roasted bone marrow that hasn’t been removed from the bones. In certain cultures, it’s considered a delicacy. Marrow is a type of tissue that can be found within the bones of many animals, including humans. It’s a porous tissue that’s mainly fat in adults. When you read this definition, you’ll learn more about bone marrow and other tissues that make up bones.
Bones, also known as osseous tissue, are organs that are mainly made up of bone tissue. Bone tissue is a form of connective tissue that is primarily composed of a collagen matrix mineralized with calcium and phosphorus crystals. Bone tissue is hard without being brittle due to the combination of flexible collagen and hard mineral crystals.
The extremely hard outer layer of bones is created by compressed bone tissue. The smooth, thick, and sturdy appearance of bone is due to cortical bone tissue. It accounts for about 80% of the adult skeleton’s total bone mass. Many bones have spongy bone tissue that fills some or all of the interior. Spongy bone, as its name implies, is porous like a sponge, with an irregular network of spaces. Spongy bone is much less dense than compact bone as a result of this. Spongy bone has a larger surface area than cortical bone, but it only accounts for 20% of total bone mass.

In mammals, a bone is a hard tissue that is a part of the vertebrate skeleton. Bones protect the body’s various organs, produce red and white blood cells, store minerals, give the body stability and support, and allow mobility. Bones have a complex internal and external structure that comes in a range of shapes and sizes. They’re light but tough, and they’re useful for a variety of things.
Osseous tissue (bone tissue) is a form of specialized connective tissue that is a hard tissue. Internally, it has a honeycomb-like matrix that aids in bone rigidity. Different forms of bone cells make up bone tissue. Osteoblasts and osteocytes play a role in the formation and mineralization of bone, while osteoclasts play a role in bone tissue resorption. The lining cells that form a protective layer on the bone surface are modified (flattened) osteoblasts. The mineralized matrix of bone tissue contains an organic component called ossein, which is primarily collagen, as well as an inorganic component made up of various salts. Bone tissue is made up of two kinds of mineralized tissue: cortical bone and cancellous bone. Bone marrow, endosteum, periosteum, nerves, blood vessels, and cartilage are among the other forms of tissue found in bones.
