Facts about Bones
Other tissue types found in bones in their entirety include marrow, the periosteum, nerves, blood vessels, and cartilage.
All bones consist of living cells embedded in the mineralized organic matrix that makes up the osseous tissue.
Secondary ossification occurs after birth, and forms the epiphyses of long bones and the extremities of irregular and flat bones.
The hard outer layer of bones is called compact bone tissue due to its minimal gaps or spaces.
Bones can serve a variety of uses, such as projectile points or artistic pigments, and can be made from endoskeletal or external bones such as antler or tusk.
The exterior of bones (except where they interact with other bones through joints) is covered by the periosteum, which has an external fibrous layer, and an internal osteogenic layer.
Preparing fleshed bones for these types of studies can involve maceration—boiling fleshed bones to remove large particles, then hand-cleaning.
Bones function to move, support, and protect the body, produce red and white blood cells, and store minerals.
Most bones perform all of these functions to one degree or another, but certain bones are more specialized for certain functions.
Bones come in a variety of shapes and have a intricate internal and external structure, allowing them to be lightweight yet strong and hard, while fulfilling their many other functions.
Intramembranous ossification mainly occurs during formation of the flat bones of the skull; the bone is formed from mesenchyme tissue.
One of the types of tissues that make up bones is the mineralized osseous tissue, also called bone tissue, a specialized connective tissue that gives bones their rigidity and honeycomb-like, three-dimensional internal structure.
In adults, red marrow is mostly found in the flat bones of the skull, the ribs, the vertebrae, and pelvic bones.
Bones are semi-rigid, porous, mineralized organs, consisting of cells in a hard matrix, that form part of the endoskeleton of vertebrates.
Endochondral ossification occurs in long bones, such as limbs; the bone is formed from cartilage.
But bones are still not as strong as teeth. The hardest part of the human body , teeth mostly consist of a calcified tissue called dentine. The tooth's dentine tissue is covered in enamel, that hard, shiny layer that you brush.Mar 18, 2011
From our head to our toes, our bones provide support for our bodies and help form our shape. The skull protects the brain and forms the shape of our face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.
