bones of the skull, vertebral colmn, and rib cage.

Function is for protection, support, and carrying of things.

Bones of the upper and lower limbs, shoulder, and hip.

Function is locomotion.

The dense outer layer of most bones.

Function is to support the whole body, protect organs, provide levers for movement,and store and release chemical elements.

Bone made up of trabeculae filled with bone marrow.

Less dense, softer and weaker than compact bone.

It typically occurs at the ends of long bones, proximal to joints, and within the interior of vertebrae.

Fulfills mainly a metabolic function.

Bones that are longer than they are wide

Long bones consist of the epiphysis region and diaphysis region.

The main or mid section of a long bone.

Composed of compact bone that surrounds the medullary (marrow) cavity which is filled with bone marrow (yellow or red).

The rounded ends of long bones at a joint connecting to to adjacent bone(s).

Exterior is compact bone and the interior is trabecular bone. The trabecular is filled with red bone marrow which produces erythrocytes.

At the joint the epiphysis is covered with articular (hyaline) cartilage.

Separating the Epiphysis and diaphysis in adults is an epiphyseal line, a remanant of the epiphyseal plate.

A double-layered protective membrane that lines all bones except at the joint of long bones.

• Outer fibrous layer is made of dense connective tissue.
• Inner osteogenic layer is compose of osteoblasts and osteoclasts.
• the periosteum is richly supplied with nerve fibers, blood, and lympathic vessels which enter the bone via nutrient foramina.

Secures the periosteum to underlying bone.

It is a matrix of connective tissue consisting of bundles of strong collagenous fibers.

Contians hematopoitic stem cells which produce red & white blood cells as well as platelets. 

In infants: Found int he medullary cavity and all areas of cancellous bone.

In addults: found in the diploe (spongy bone) of flat bones and the head of the femur & humerus.

Found in the medullary cavity. Mainly made up of fat cells.

There is more yellow marrow as one ages.

Your body can convert yellow marrow back to red if it requires a significant amount of RBC formation.

Bones whose principal requirement is either extensive protection of the provision of broad surfaces for muscular attachement.

Examples are the cranium, illum, sternum, and rib cage.

They have no epiphyses or diaphyses

Contain bone marrow between the trabeculae.

• A condition where the bone mineral density is reduced and bone deteriorates. Excess bone is lost to meet metabolic needs.
• Osteoporosis is evident if bone mineral content falls 2.5 SD below the young normal mean.
• Occurs more often in women.

The spongy bone structure or tissue of hte internal parts of flat, short, and irregular bones.

Cmparable to the medullary cavity in long bones.
