Bone Structure and Function Quiz

Bone True/False Questions

• Osteoclasts: Cells that break down bone for remodeling. (True/False question)
• Short Bones: Examples include carpals and metacarpals. (True/False question)
• Connective Tissue: Holds bones together, enabling movement and stability. (True/False question)
• Osteoblasts: Primary building blocks providing structure and support. (True/False question)

Bone Definition Questions

• Osteoblasts: Bone-building cells depositing minerals and forming tissue.
• Osteoclasts: Cells breaking down bone for remodeling.
• Cartilage: Flexible tissue cushioning joints and providing structure.
• Compact Bone: Outer layer providing strength and protection.
• Spongy Bone: Bone formation continues at ends, forming growth plates.
• Red Marrow: Produces red blood cells, abundant in children; stores fat, found in long bone cavities.
• Yellow Marrow: Stores fat; found in long bone cavities.

Bone Structure and Function

• System Components: Includes skull, spine, ribcage, central axis, bones, cartilage, and connective tissues.
• Bones: Grow, repair, and adapt to stress.
• Osteocytes: Mature cells maintaining bone structure and responding to stress.
• Axial Skeleton: Comprises skull, spine, ribcage, and attaches to the axial skeleton, includes bones, cartilage, and connective tissues, and holds bones together.
• Appendicular Skeleton: Comprises limbs; attaches to the axial skeleton.

Marrow Functions

• Marrow Function: Crucial for blood cell production and energy storage.
• Secondary Ossification: Osteoblasts replace cartilage with bone from the center outward.
• Mature Bone: Reaches adult form but continues to remodel.

Bone Types

• Short Bones: Example includes vertebrae.
• Irregular Bones: Example includes the scapula.
• Long Bones: Example includes the femur and humerus.
• Flat Bones: Example includes the skull.

Bone Development

• Embryonic Bones: Start as cartilage models.
• Bone Density: Can decrease with age
• Bone Growth: Bones grow, repair, and adapt to stress.
• Bone Regeneration: Bones heal themselves through regeneration.
• Bone Activity: Bones are alive and constantly changing.
• Bone Response: Bones strengthen in response to physical activity.
• Cartilage Model: Embryonic bone starts as cartilage models (True/False question).
• Primary Ossification: Bone formation continues at ends, forming growth plates (True/False question).
• Secondary Ossification: Osteoblasts replace cartilage with bone, outward (True/False question).
• Intramembranous Ossification: Comprises limbs and attaches to the axial skeleton (True/False question)
