Multiple Choice Questions Skeletal System Questions
Question 1 of 5
In one hand, there are carpals, metacarpals and phalanges.
Correct Answer: C
Rationale: One hand has 8 carpals (wrist), 5 metacarpals (palm), and 14 phalanges (fingers: 2 in thumb, 3 each in others). '8-5-14' matches this anatomy.
Question 2 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 3 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 4 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 5 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.
