Match the anatomy of the long bone with its correct description:

Articular/Hyaline Cartilage

• Joint surface where one bone meets another

• External sheath covering the bone. It has a tough outer fibrous layer of collagen and an inner layer of bone forming cells

• Outer layer of dense white osseous tissue

• Found at the ends of the long bone in the center. It is loosely organized osseous tissue

Match the anatomy of the long bone with its correct description:

Periosteum

• Joint surface where one bone meets another

• External sheath covering the bone. It has a tough outer fibrous layer of collagen and an inner layer of bone forming cells

• Outer layer of dense white osseous tissue

• Found at the ends of the long bone in the center. It is loosely organized osseous tissue

Match the anatomy of the long bone with its correct description:

Cortical (Compact) Bone

• Joint surface where one bone meets another

• External sheath covering the bone. It has a tough outer fibrous layer of collagen and an inner layer of bone forming cells

• Outer layer of dense white osseous tissue

• Found at the ends of the long bone in the center. It is loosely organized osseous tissue

Match the anatomy of the long bone with its correct description:

Spongy Bone

• Joint surface where one bone meets another

• External sheath covering the bone. It has a tough outer fibrous layer of collagen and an inner layer of bone forming cells

• Outer layer of dense white osseous tissue

• Found at the ends of the long bone in the center. It is loosely organized osseous tissue

Match the anatomy of the long bone with its correct description:

Epiphysis

• Proximal and Distal ends of a bone

  Mature bones often exhibit an epiphysial line between the epiphysis & diaphysis

• The shaft of the bone

• Thin layer of connective tissue lining the central canal

• Contains bone marrow

Match the anatomy of the long bone with its correct description:

Diaphysis

• Proximal and Distal ends of a bone

  Mature bones often exhibit an epiphysial line between the epiphysis & diaphysis

• The shaft of the bone

• Thin layer of connective tissue lining the central canal

• Contains bone marrow

Match the anatomy of the long bone with its correct description:

Endosteum

• Proximal and Distal ends of a bone

  Mature bones often exhibit an epiphysial line between the epiphysis & diaphysis

• The shaft of the bone

• Thin layer of connective tissue lining the central canal

• Contains bone marrow

Match the anatomy of the long bone with its correct description:

Medullary Cavity

• Proximal and Distal ends of a bone

  Mature bones often exhibit an epiphysial line between the epiphysis & diaphysis

• The shaft of the bone

• Thin layer of connective tissue lining the central canal

• Contains bone marrow

Match the bone cells with its correct description:

Osteoblasts

• They create bone tissue and promote its mineralization

• They are matured bone cells that assist with bone remodeling

• They are bone-dissolving cells which assists with bone remodeling
