Osteopenia is when your bones are weaker than normal but not so far gone that they break easily, which is the hallmark of osteoporosis. Your bones are usually at their densest when you're about 30. Osteopenia, if it happens at all, usually occurs after age 50.

Osteoporosis is a health condition that weakens bones, making them fragile and more likely to break. It develops slowly over several years and is often only diagnosed when a fall or sudden impact causes a bone to break (fracture). The most common injuries in people with osteoporosis are: broken wrist.

Bones are organs that consist primarily of bone tissue, also called osseous tissue. Bone tissue is a type of connective tissue consisting mainly of a collagen matrix that is mineralized with calcium and phosphorus crystals.

Osteoporosis, or porous bone, is a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased risk of fractures of the hip, spine, and wrist. Men as well as women are affected by osteoporosis, a disease that can be prevented and treated.

In some cases, certain risk factors make it more likely that a bone will fail to heal. When a broken bone fails to heal it is called a "nonunion." A "delayed union" is when a fracture takes longer than usual to heal.

The tough, thin outer membrane covering the bones is called the periosteum. Beneath the hard outer shell of the periosteum are tunnels and canals through which blood and lymphatic vessels run to carry nourishment for the bone.

Bone loss before osteoporosis (osteopenia) The stage before osteoporosis is called osteopenia. This is when a bone density scan shows you have lower bone density than the average for your age, but not low enough to be classed as osteoporosis. Osteopenia does not always lead to osteoporosis.

What are bones made of? Around 70 percent of your bones are not living tissue, but hard minerals like calcium. The outside of the bone is called the cortical bone. It's hard, smooth, and solid.

Fibula – Fibula is the Latin word for a clasp and especially the needle-like clasping part. Evidently, the smaller of the two leg bones was thought to resemble that object.

Spongy (Cancellous) Bone. Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) (Figure 7).

The osteon or haversian system /həˈvɜːr. ʒən/ (named for Clopton Havers) is the fundamental functional unit of much compact bone. Osteons are roughly cylindrical structures that are typically between 0.25 mm and 0.35 mm in diameter.

Leg bones are usually some of the strongest in the body and it takes a big impact such as a serious fall or a car accident for them to break. A fracture that occurs lower down the femur is classed as a broken leg rather than hip and is one of the most painful breaks to experience.

Skeleton. Birds have a lightweight skeleton made of mostly thin and hollow bones. The keel-shaped sternum (breastbone) is where the powerful flight muscles attach to the body. Birds have a smaller total number of bones than mammals or reptiles.
