Bone tissue comprises cortical bone and cancellous bone, although bones may also contain other kinds of tissue including bone marrow, endosteum, periosteum, nerves, blood vessels, and cartilage. In the human body at birth, approximately 300 bones are present.
Bone is a rigid body tissue consisting of cells embedded in an abundant hard intercellular material. Bone tissue makes up the individual bones of the skeletons of vertebrates. Its two principle components are collagen and calcium phosphate.
Common bone diseases often affect the bone density, e.g. in young children due to malnutrition. For example, rickets is a bone deformity seen in young children who lack vitamin D.
Bones are composed of two types of tissue. Compact (cortical) bone is a hard outer layer that is dense, strong, and durable. It makes up around 80% of adult bone mass and forms the outer...
A typical bone in your body contains 3 types of tissue—a hard outer tissue, a sponge-like inner tissue, and smooth tissue at the ends.
Conditions and Disorders What are the common conditions and disorders that affect bones? Broken bones and osteoporosis are the most common bone issues. A fracture is the medical name for a broken bone. Any bone can break. It’s more common in smaller, weaker bones. Breaking stronger bones can happen during a serious trauma like a car accident.
BONE is an interdisciplinary forum for the rapid publication of original articles and reviews on basic, translational, and clinical aspects of bone and mineral metabolism, including rare bone diseases.
Although bone cells compose a small amount of the bone volume, they are crucial to the function of bones. Four types of cells are found within bone tissue: osteoblasts, osteocytes, osteogenic cells, and osteoclasts (Figure 5).
