Questions for Skeletal System Questions
Question 1 of 5
The hand bones are the metacarpals.
Correct Answer: B
Rationale: The hand includes carpals (wrist), metacarpals (palm), and phalanges (fingers). Saying only metacarpals are hand bones is incomplete, making 'False' correct.
Question 2 of 5
Bones assist in all phases of respiration.
Correct Answer: B
Rationale: Bones (ribs, sternum) assist inhalation/exhalation by moving, but not all respiration phases (e.g., gas exchange in lungs). This makes 'False' correct.
Question 3 of 5
Which one of the following bones is located in the head?
Correct Answer: D
Rationale: The cranium, part of the skull, is located in the head, protecting the brain. The scapula is the shoulder, phalanges are fingers/toes, and tarsals are ankle bones, making 'Cranium' correct.
Question 4 of 5
What type of bone is the Patella?
Correct Answer: D
Rationale: The patella (kneecap) is a sesamoid bone, embedded in the quadriceps tendon, enhancing leverage and protecting the knee. Flat, short, and irregular don’t apply, making 'Sesamoid' correct.
Question 5 of 5
During 'arm side raises' exercise which involves the shoulder ball and socket synovial joint, which joint action is being used?
Correct Answer: B
Rationale: Arm side raises lift arms laterally (abduction) and lower them (adduction) using the shoulder’s ball-and-socket joint. Extension/flexion is forward/back, rotation is circular, making 'Abduction and Adduction' correct.
