Skeletal System Test review

How does the structure of compact bone contribute to its function as a weight-bearing pillar in the body?

• The compact bone is made of trabeculae that provide flexibility.

• The compact bone is made of osteons, which are long cylinders that act as weight-bearing pillars.

• The compact bone is filled with red bone marrow that supports weight.

• The compact bone is composed of cartilage that absorbs shock.

Explain how the process of bone remodeling helps maintain bone health and prevent fractures.

• Bone remodeling involves the deposition of cartilage to strengthen bones.

• Bone remodeling involves the crystallization of calcium to harden bones.

• Bone remodeling involves the resorption of old bone and formation of new bone to maintain bone strength and flexibility.

• Bone remodeling involves the conversion of spongy bone to compact bone.

Discuss the role of osteocytes in bone maintenance and how they respond to mechanical stress.

• Osteocytes build new bone tissue in response to stress.

• Osteocytes absorb bone tissue to reduce stress.

• Osteocytes maintain bone structure and signal osteoblasts and osteoclasts in response to stress.

• Osteocytes convert spongy bone to compact bone under stress.

Analyze how the classification of bones by shape relates to their function in the body.

• Long bones are primarily for protection, while flat bones are for movement.

• Short bones provide leverage, while irregular bones store minerals.

• Long bones act as levers for movement, while flat bones provide surfaces for muscle attachment.

• Irregular bones are for energy storage, while short bones are for blood cell formation.

Evaluate the importance of synovial fluid in synovial joints and its role in joint movement.

• Synovial fluid acts as a shock absorber to prevent joint damage.

• Synovial fluid provides nutrients to the cartilage in the joint.

• Synovial fluid acts as a lubricant to reduce friction and facilitate smooth joint movement.

• Synovial fluid hardens to stabilize the joint during movement.

How does the process of endochondral ossification contribute to bone growth and development?

• It involves the direct transformation of fibrous tissue into bone.

• It involves the replacement of cartilage with bone tissue, allowing for bone elongation.

• It involves the deposition of calcium on the bone surface.

• It involves the conversion of compact bone to spongy bone.

Assess the role of ligaments in joint stability and how they contribute to joint function.

• Ligaments connect muscles to bones, allowing for movement.

• Ligaments connect bones to bones, providing stability and limiting excessive movement.

• Ligaments produce synovial fluid to lubricate joints.

• Ligaments store minerals for bone health.

Explain how the structure of spongy bone supports its function in the skeletal system.

• Spongy bone is dense and compact, providing strength.

• Spongy bone contains trabeculae that help resist stress and house bone marrow.

• Spongy bone is filled with synovial fluid for lubrication.

• Spongy bone is made of cartilage for flexibility.

Analyze the impact of bone remodeling on calcium homeostasis in the body.

• Bone remodeling decreases blood calcium levels by storing calcium in bones.

• Bone remodeling increases blood calcium levels by releasing calcium from bones.

• Bone remodeling has no effect on blood calcium levels.

• Bone remodeling only affects phosphate levels, not calcium.

Discuss the significance of bone markings and how they relate to muscle and ligament attachment.

• Bone markings are smooth surfaces that reduce friction.

• Bone markings are projections and depressions that serve as attachment points for muscles and ligaments.

• Bone markings are cavities that store synovial fluid.

• Bone markings are areas where bone growth occurs.
