Multiple Choice Questions on Skeletal System Questions
Question 1 of 5
How many bones make up the human spine?
Correct Answer: B
Rationale: The human spine (vertebral column) consists of 33 bones: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral (fused into the sacrum), and 4 coccygeal (fused into the coccyx). In adults, the sacral and coccygeal bones fuse, but the total count remains 33 individual vertebrae.
Question 2 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 3 of 5
Which is the more elastic part of an intervertebral disc?
Correct Answer: B
Rationale: The nucleus pulposus, the inner core of an intervertebral disc, is gelatinous and elastic, allowing flexibility and shock absorption. The anulus fibrosus, the outer fibrous ring, is tougher and less elastic, providing strength.
Question 4 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.

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.
