Multiple Choice Questions Skeletal System Questions
Question 1 of 5
The joint between the atlas and axis is a joint.
Correct Answer: B
Rationale: The atlas (C1) and axis (C2) form a pivot joint, allowing rotation (e.g., head shaking 'no'). Gliding is sliding, condyloid is two-plane, and hinge is one-plane, making 'pivot' correct.
Question 2 of 5
In addition to adequate intake of vitamin D and calcium, walking and weight training will increase bone strength and decrease the risk of osteoporosis.
Correct Answer: A
Rationale: Vitamin D and calcium build bone, while weight-bearing exercises (walking, weight training) stimulate osteoblasts, increasing strength and reducing osteoporosis risk. This is well-supported, making 'True' correct.
Question 3 of 5
The ribs attach to the lumbar vertebra in the back.
Correct Answer: B
Rationale: Ribs attach to the 12 thoracic vertebrae, not lumbar, forming the thoracic cage. Lumbar vertebrae are below, making 'False' correct.
Question 4 of 5
The largest coxal bone is the ischium.
Correct Answer: B
Rationale: The ilium is the largest coxal bone region, forming the upper pelvis. The ischium is smaller, supporting sitting, making 'False' correct.
Question 5 of 5
A joint cavity filled with fluid gives synovial joints their freedom of movement.
Correct Answer: A
Rationale: Synovial joints (e.g., knee) have a cavity with synovial fluid, reducing friction and enabling free movement. This is accurate, making 'True' correct.
