Multiple Choice Questions Skeletal System Questions
Question 1 of 5
Explain why female hips are broader then male hips.
Correct Answer: A
Rationale: Female hips are broader due to flared iliac bones, adapting the pelvis for childbirth. Ischial and pubic differences exist, but ilium flaring is primary; thickness is unrelated, making 'Female iliac bones are more flared' correct.
Question 2 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 3 of 5
What mineral is stored in bone?
Correct Answer: B
Rationale: Bones store calcium, a key mineral for strength and physiological functions (e.g., muscle contraction). Vitamin C is not stored, oxygen is in lungs, and potassium is cellular, making 'calcium' correct.
Question 4 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 5 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.
