Multiple Choice Questions Skeletal System Questions
Question 1 of 5
Identify the three sections of the sternum from most superior to most inferior.
Correct Answer: D
Rationale: The sternum has three parts, from superior to inferior: manubrium (top, rib 1-2 attachment), body (middle, rib 3-7 attachment), and xiphoid process (bottom). 'manubrium, body and xiphoid process' is the correct order.
Question 2 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 3 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 4 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 5 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.
