Multiple Choice Questions About Skeletal System Questions
Question 1 of 5
There are two sections to the human skeleton: axial and appendicular, the former containing the skull, vertebral column and what else?
Correct Answer: A
Rationale: The axial skeleton includes the skull, vertebral column, and thoracic cage (ribs and sternum), which protect vital organs like the heart and lungs. The girdles (pectoral and pelvic) are part of the appendicular skeleton, not the axial, making 'thoracic cage' the correct addition.
Question 2 of 5
If the vertebrae are kept together by ligaments that are longitudinal, in what direction are these ligaments running?
Correct Answer: B
Rationale: Longitudinal ligaments run lengthwise along the vertebral column (e.g., anterior and posterior longitudinal ligaments), stabilizing the vertebrae vertically. Transverse is crosswise, and oblique is diagonal—neither matches 'longitudinal.'
Question 3 of 5
In the appendicular skeleton, the ... girdle is comprised of the clavicle and the scapula, which together give structure to the shoulder.
Correct Answer: B
Rationale: The pectoral girdle, part of the appendicular skeleton, consists of the clavicle and scapula, supporting the shoulder and upper limbs. 'Upper' is descriptive but not the anatomical term.
Question 4 of 5
Which one out of the following carpals is spelled incorrectly?
Correct Answer: D
Rationale: Options are: scaphoid, lunate, triquetrum, chamate. 'Chamate' is a misspelling of 'hamate,' a carpal bone with a hook-like process. All others are correctly spelled carpals.
Question 5 of 5
How many tarsals are there in the tarsus?
Correct Answer: A
Rationale: The tarsus (ankle) contains 7 tarsal bones: talus, calcaneus, navicular, cuboid, and three cuneiforms (medial, intermediate, lateral), forming the foot’s proximal structure.
