Multiple Choice Questions on Skeletal System Questions
Question 1 of 5
What is the name of the foramen through which the spinal cord passes at the base of the skull?
Correct Answer: B
Rationale: The foramen magnum, located in the occipital bone, is the large opening at the skull’s base through which the spinal cord passes to connect with the brainstem. 'Maximum' is not an anatomical term here.
Question 2 of 5
The clavicle has a/an ... end, where it attaches to the manubrium, and a/an ... end, which joins the scapula.
Correct Answer: B
Rationale: The clavicle’s sternal end articulates with the manubrium (sternum), and its acromial end joins the scapula’s acromion, forming the shoulder’s structure. 'Sternal/acromial' matches this medial-to-lateral orientation.
Question 3 of 5
The five metacarpals, which make up the palm of the hand and connect to the phalanges, are named one through five from ... .
Correct Answer: B
Rationale: Metacarpals are numbered 1 to 5 from thumb (lateral) to pinky (medial) in anatomical position, aligning with phalange numbering and standard convention.
Question 4 of 5
Which big tarsal, apart from the talus, makes up the ankle?
Correct Answer: A
Rationale: The calcaneus (heel bone), alongside the talus, forms the ankle’s major structure, supporting weight and articulating with the tibia/fibula. Cuboid and navicular are more distal.
Question 5 of 5
How many pairs of ribs does an adult human typically have?
Correct Answer: B
Rationale: An adult human typically has 12 pairs of ribs (24 total): 7 true pairs (attaching to the sternum), 3 false pairs (indirectly attached), and 2 floating pairs (no sternal attachment). 10 undercounts, while 14 and 16 exceed the standard anatomical count.
