Bone Tissue

Which classification of bone protects organs or provides a large surface area for the attachment of muscles?

• Long bones
• short bones
• flat bones
• irregular bones

The central, shaftlike portion of a long bone is called the

• epiphysis
• diaphysis
• endosteum
• periosteum

Which substance covers the surface of the epiphysis of a long bone?

• Red bone marrow
• Trabeculae
• Fibrocartilage
• Articular Cartilage

The medullary cavity in most adults is filled with

• Red bone marrow
• Yellow Bone Marrow
• Spongy Bone
• The endosteum

Which type of bone cell helps form bone, specifically the bone’s matrix?

• Ostoblasts
• Osteoclasts
• Fibroblasts
• Chondrocytes

What makes bone unique from other connective tissue?

• It is nonliving tissue.
• Its matrix is hard and calcified
• It doesn’t contain blood vessels.
• It is self-contained and doesn’t interact with other body systems.

Which of the following typically occurs when bones experience an increase in load?

• Osteocytes become more active dissolving unhealthy bone.
• Bone fibers become more compact, increasing tensile strength
• Osteocytes become more active creating new bone.
• The deposition of calcium salts increases, which increases compressional strength.

Trabeculae are arranged in such a way so as to

• Allow for tensile strength
• Allow room for bone marrow
• Lighten bone
• Strengthen bone

The basic structural unit of compact bone is

• a lacunae.
• an osteon.
• a canaliculi.
• a lamellae.

In a developing fetus, the bones of the skull and face begin as

• fibrous connective tissue.
• cartilage.
• bone.
• elastic connective tissue.
