Skeletal 2

Primary ossification center

The center part of the diaphysis, where bone first begins to appear.

Bone growth

occurs by the deposition of new bone lamellae onto existing bone or other connective tissue.

Appositional growth

This process increases the bone in width, or diameter.

Epiphyseal plate.

Growth in the length of a bone, which is the major source of increased height in an individual.

Bone remodeling

Involves the removal of existing bone by osteoclasts and the deposition of new bone by osteoblasts.

Remodeling

Responsible for changes in bone shape, the adjustment of bone to stress, bone repair, and calcium ion regulation in the body fluids.

Callus

The network of fibers and islets of cartilage between the two bone fragments.

Bone

the major storage site for calcium in the body, and movement of calcium into and out of bone helps determine blood calcium levels.

Open Fracture

If the bone protrudes through the skin.

Closed Fracture

If the skin is not perforated.

Complete Fracture

If the fracture totally separates the two bone fragments.

Greenstick fracture

An incomplete fracture that occurs on the convex side of the curve of a bone.

Incomplete Fracture

If the fracture doesn't totally separates the two bone fragments.

Comminuted fracture

One in which the bone breaks into more than two fragments.

Impacted fracture

Occurs when one of the fragments of one part of the bone is driven into the spongy bone of another fragment.

Linear

Parallel to the long axis.

Transverse

At right angles to the long axis.

Oblique (Spiral)

At an angle other than a right angle to the long axis.

Foramen

Hole in a bone; usually exists in a bone because some structure, such as a nerve or blood vessel, passes through the bone at that point.

Canal (Meatus)

The hole is elongated into a tunnel-like passage through the bone.

Tubercle

Depression in a bone

Process

Projection from a bone

Condyle

The smooth, rounded end of a bone, where it forms a joint with another bone.
