Multiple Choice Questions About Skeletal System Questions
Question 1 of 5
Which one of the following bones is not part of the Axial Skeleton?
Correct Answer: C
Rationale: The axial skeleton includes the skull, vertebral column (vertebrae), sternum, and ribs, forming the body’s central axis. The ulna, a forearm bone, is part of the appendicular skeleton (limbs and girdles), making 'Ulna' the correct answer for what is not axial.
Question 2 of 5
The skull is what type of joint?
Correct Answer: B
Rationale: The skull’s joints are sutures, fibrous and fixed (immovable) in adults, locking cranial bones. Sliding (gliding) and synovial are movable, and slightly movable doesn’t fit, making 'Fixed Joints' correct.
Question 3 of 5
Which of the following is the term used to describe an 'Exaggerated curve in the 'lumbar' region of the spine'?
Correct Answer: A
Rationale: Lordosis is an exaggerated inward lumbar spine curve (swayback). Kyphosis is thoracic outward, scoliosis is lateral, and arthritis is joint inflammation, making 'Lordosis' correct.
Question 4 of 5
Which of the following describes the movements known as pronation and supination?
Correct Answer: C
Rationale: Pronation (palm down) and supination (palm up) involve radius crossing over ulna, twisting the wrist while the elbow stays fixed. Other options describe flexion, eversion/inversion, or circumduction. Answer is C, per the document.
