Structure of a Long Bone

What is the function of the epiphysis?

What is located in the middle of a long bone?

Blood vessels in long bones deliver nutrients.

What type of bone is found in the outer layer of most other types of bone?

The periosteum is important for bone growth and nutrition.

What is the function of yellow marrow?

Where is yellow bone marrow stored?

Spongy bone is where red marrow is stored and blood cell production occurs.

What covers the ends of the bone to reduce friction between bones?

Structure of a Long Bone

Epiphysis: Ends of the long bone; facilitates joint movement; composed of spongy bone (houses bone marrow and red blood cells) and covered by cartilage.
Diaphysis: Central, long, and tubular portion of the long bone; made up of hard, compact bone for structural support.
Blood Vessels: Essential components that run through the long bone; responsible for delivering nutrients to maintain bone health.
Compact Bone: Dense and solid layer found on the outer surface of most bones, providing strength and stability.
Periosteum: Thin, shiny white membrane surrounding the bone; crucial for bone growth, repair, nutrition, and attachment of ligaments and tendons.
Yellow Marrow: Located within the bone; serves as storage for energy and production of cells.
Medullary Cavity: Hollow space within the diaphysis; primarily stores yellow bone marrow.
Spongy Bone: Contains red marrow, where blood cell production occurs; designed to absorb shock and strain during movement.
Articular Cartilage: Covers bone ends at joints; minimizes friction between bones for smooth movement.
