Classification of Bones/Joints

Long bones are best described as bones that:**

   * A. Are flat and protect internal organs

   * B. Consist of a body and two ends and are found only in the appendicular skeleton

   * C. Are composed entirely of cancellous bone

   * D. Are found only in the axial skeleton

  Consist of a body and two ends and are found only in the appendicular skeleton

The hard, dense outer layer of most bones is known as the:**

   * A. Spongy bone

   * B. Medullary cavity

   * C. Compact bone (cortex)

   * D. Periosteum

Compact bone (cortex)

Spongy (cancellous) bone is primarily located:**

   * A. In the medullary cavity of long bones

   * B. On the external surface of all bones

   * C. Inside the shell of compact bone, especially at the ends of long bones

   * D. Only in flat bones

Inside the shell of compact bone, especially at the ends of long bones

Which type of bone marrow is responsible for the production of red blood cells?**

   * A. Yellow marrow

   * B. Fatty marrow

   * C. Red marrow

   * D. Compact marrow

Red marrow

The medullary cavity of a long bone typically contains:**

   * A. Yellow marrow

   * B. Red bone marrow

* C .Spongy bone

   * D. Articular cartilage

Yellow marrow- store fat and serves as energy store

The periosteum is best described as a structure that:**

   * A. Covers the articulating surfaces of bones

   * B. Is composed of hyaline cartilage

   * C. Covers bone except at articulating surfaces and aids in growth and repair

   * D. Lines the medullary cavity

Covers bone except at articulating surfaces and aids in growth and repair

Which cartilage type appears clear or glossy and covers the ends of bones at joints?**

   * A. Fibrocartilage

   * B. Elastic cartilage

   * C. Hyaline cartilage

   * D. Articular bone

Hyaline cartilage
