Study Notes
Long Bone Components
-
Articular Cartilage: Smooth, glossy tissue covering the ends of bones at joints, reducing friction and absorbing shock during movement.
-
Spongy Bone: Lighter, less dense bone tissue found at the ends of long bones and within the interiors; has a porous structure that houses bone marrow.
-
Epiphyseal Plate: Known as the growth plate, this layer of cartilage at the end of long bones allows for growth in length during development.
-
Periosteum: A dense, fibrous membrane covering the outer surface of bones, providing support and nourishment; contains nerves and blood vessels.
-
Compact Bone: Hard, dense outer layer of bone providing strength and protection; makes up the majority of the bone structure.
-
Marrow (Medullary) Cavity: Hollow space within the diaphysis of long bones; contains bone marrow, which is responsible for the production of blood cells.
-
Yellow Marrow: Fatty tissue found in the medullary cavity of long bones; serves as an energy reserve and can convert to red marrow if needed for blood cell production.
-
Diaphysis: The long, tubular shaft of a long bone; primarily composed of compact bone, providing stability and support.
-
Metaphysis: Region between the diaphysis and epiphysis; contains the epiphyseal plate, playing a key role in the growth of long bones.
-
Epiphysis: The rounded ends of long bones that articulate with neighboring bones; contains spongy bone and is involved in joint movement.
-
Artery: Blood vessel that supplies oxygenated blood to the bones; crucial for bone health and maintenance.
