The bones perform five main functions for the body: Provide support: The skeletal system provides structural support for the entire body. Individual bones or groups of bones provide a framework for the attachment of soft tissues and organs.

Bone is a complex, living, constantly changing tissue. The architecture and composition of cancellous and cortical bone allow the skeleton to perform its essential mechanical functions.
The stiffer cortical bone responds more slowly to changes in loads while cancellous bone has a much larger surface area per unit volume bone structure and function a greater rate of metabolic activity.
Bones: Types, structure, and function
Fibrocartilage can be found within the knee joint, between the pubic bones of the pelvis, and between the spinal vertebrae. Cartilage heals poorly, and damaged fibrocartilage in joints such as the knee can interfere with normal movements.
The knee contains both hyaline cartilage and fibrocartilage. The hyaline cartilage covers bony surfaces; fibrocartilage pads in the joint prevent contact between bone structure and function during movement.
Injuries to the joints can produce tears in the fibrocartilage pads, and the tears do not heal. Eventually, joint mobility is severely reduced.

Bone structure and function.
This information is provided by the Cleveland Clinic and is not intended to replace the medical advice of your doctor or healthcare provider. Bones can release or absorb alkaline salts, helping blood to stay at the right pH level.
Bones can absorb heavy metals and other toxic elements from the blood. Bones release hormones bone structure and function act on the kidneys and influence blood sugar regulation and fat deposition. Bones can raise or reduce calcium in the blood by forming bone, or breaking it down in a process called resorption.
Types of bone There are five types of bones in bone structure and function human body: These are mostly compacted bone with little marrow and include most of the bones in the limbs.
These bones tend to support weight and help movement. Only a thin layer of compact bone, these include bones of the bone structure and function and ankle. Usually bones that are thin and curved. Osteocytes have many processes that reach out to meet osteoblasts and other osteocytes probably for the purposes of communication.

Osteoclast[ edit ] Osteoclasts are bone structure and function large multinucleate cells that are responsible for the breakdown of bones by the process of bone resorption. New bone is then formed by the osteoblasts.
Bone is constantly remodelled by the resorption of osteoclasts and created by osteoblasts. These lacunae are the result of surrounding bone tissue that has been reabsorbed.
Upon arrival, active enzymes, such as tartrate resistant acid bone structure and functionare secreted against the mineral substrate. This matrix consists of organic components, mainly type I collagen — "organic" referring to materials produced as a result of the human body — and inorganic components, primarily hydroxyapatite and other salts of calcium and phosphate.

These effects are synergistic. Collagen consists bone structure and function strands of repeating units, which give bone tensile strength, and are arranged in an overlapping fashion that prevents shear stress. The function of ground substance is not fully known. Woven bone, also known as fibrous bone which is characterized by a haphazard organization of collagen fibers and is mechanically weak.
Woven bone is produced when osteoblasts produce osteoid rapidly, which occurs initially in all fetal bones, bone structure and function is later replaced by more resilient lamellar bone.
