Multiple Choice Questions Skeletal System Questions
Question 1 of 5
The suture between the parietal and occipital bones is the suture.
Correct Answer: B
Rationale: The lambdoidal suture separates the parietal bones from the occipital bone at the skull’s posterior. Coronal is frontal-parietal, sagittal is between parietals, and squamosal is temporal-parietal, making 'lambdoidal' correct.
Question 2 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 3 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 4 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 5 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.
