Anatomy of the long bone

Long expanded ends (Arm and leg bones)

Humerus, ulna, radius, femur, tibia, fibula, metacarpals, phalanges, metatarsals, and phalanges.

Structures of the long bone

Periosteum

Medullary cavity

Diaphysis

Endosteum

Epiphyes

Spongy bone

Compact bone

Projections

Expanded ends of bones that form joints with adjacent bones

Articular cartilage (hyaline cartilage) covers the epiphyes

The shaft of the bone is the diaphysis

A tough layer of dense connective tissue that covers the bone, and is continuous with ligaments and tendons

Filled with a special type of connective tissue called bone marrow

A thin layer of cells on the medullary cavity

Contains a hollow chamber (medullary cavity)

Bony processes provide attachment sites for tendons and ligaments, opening or grooves for blood vessels and nerves, and depressions for articulation (forming a joint with another bone)

Tightly packed tissue that makes up the diaphysis wall

Consists of many branching bony plates called trabeculae
