Anatomy of a Long Bone

Delivers nutrients and oxygen to the bone cells

• Yellow marrow
• Red marrow
• Blood vessel
• Medullary cavity

Enters and exits bone through the nutrient foramen

• Nerve root
• Blood vessel
• Adipose tissue
• Red marrow

Full of red marrow

• Compact bone
• Medullary cavity
• Nutrient foramen
• Spongy bone

Full of stem cells

• Yellow marrow
• Red marrow
• Periosteum
• Compact bone

Growth plates

• Epiphyseal plates
• Articular cartilage
• Periosteum
• Endochondral plates

Has layers called lamella (type of bone)

• Spongy bone
• Compact bone
• Dense bone
• Layered bone

Hollow space inside the diaphysis

• Spongy bone
• Nutrient foramen
• Articular cavity
• Medullary cavity

How newly made blood cells leave the bone (not the hole)

• Blood vessel
• Red marrow
• Yellow marrow
• Epiphyseal foramen

Layer that lines the medullary cavity

• Periosteum
• Endosteum
• Articular cartilage
• Spongy bone

Layer that lines the outside of the bone

• Periosteum
• Endosteum
• Articular cartilage
• Compact bone
