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
