150 Multiple-Choice Questions with Answers and Rationales
SECTION 1: ARTICULATIONS & JOINTS (Questions 1–35)
🟢 1. Which of the following structural joint classifications is characterized by the presence
of a joint cavity?
A. Fibrous joints
B. Cartilaginous joints
C. Synovial joints
D. Amphiarthrotic joints
:: C. Synovial joints – Synovial joints are the only structural classification that possesses a
synovial (joint) cavity filled with synovial fluid. Fibrous and cartilaginous joints lack a joint

A. Synarthrosis
B. Amphiarthrosis
C. Diarthrosis
D. Gomphosis

A. Suture
B. Syndesmosis
C. Gomphosis
, D. Symphysis

(hyaline) cartilage that covers the ends of bones, reducing friction and absorbing shock.
They also possess a joint cavity and synovial fluid.
🟢 8. The pubic symphysis is classified functionally as:
A. Synarthrosis
B. Amphiarthrosis
C. Diarthrosis
D. Synostosis
:: B. Amphiarthrosis – The pubic symphysis is a cartilaginous joint that allows slight
movement, making it functionally amphiarthrotic.
🟢 9. Which of the following joints is an example of a hinge joint?
A. Shoulder joint
B. Hip joint
C. Elbow joint
D. Radioulnar joint
:: C. Elbow joint – The elbow joint is a hinge joint that allows flexion and extension in a
single plane (uniaxial movement). The shoulder and hip are ball-and-socket joints, and the
radioulnar joint is a pivot joint.
🟢 10. Articular discs (menisci) are found in which of the following joints?
A. Shoulder joint
B. Knee joint
C. Hip joint
D. Elbow joint
:: B. Knee joint – The knee joint contains medial and lateral menisci (articular discs) that
improve fit between bones, absorb shock, and distribute weight.
🟢 11. Which type of synovial joint allows for rotational movement around a single axis?
, A. Hinge joint
B. Pivot joint
C. Saddle joint
D. Condyloid joint
:: B. Pivot joint – Pivot joints allow rotation around a single axis (uniaxial). Examples include
the atlantoaxial joint and the proximal radioulnar joint.
🟢 12. A syndesmosis is structurally classified as a:
A. Fibrous joint
B. Cartilaginous joint
C. Synovial joint
D. Bony joint
:: A. Fibrous joint – A syndesmosis is a fibrous joint where bones are connected by an
interosseous ligament, such as the tibiofibular syndesmosis.
🟢 13. Which of the following joints is multiaxial?
A. Elbow joint
B. Knee joint
C. Shoulder joint
D. Interphalangeal joint
:: C. Shoulder joint – The shoulder joint (glenohumeral) is a ball-and-socket joint that allows
movement in multiple axes (multiaxial). The elbow and interphalangeal joints are uniaxial
hinge joints.
🟢 14. Bursae and tendon sheaths are associated with:
A. Fibrous joints
B. Cartilaginous joints
C. Synovial joints
D. Amphiarthroses
:: C. Synovial joints – Bursae and tendon sheaths are accessory structures of synovial joints
that reduce friction between tendons, ligaments, and bones during movement.
🟢 15. Which of the following is NOT a function of synovial fluid?
A. Reducing friction between articular cartilages
B. Nourishing chondrocytes of articular cartilage
C. Providing shock absorption
D. Producing new bone tissue
:: D. Producing new bone tissue – Synovial fluid lubricates, nourishes cartilage, and absorbs
shock, but it does not produce bone tissue. Bone formation is carried out by osteoblasts.
🟢 16. The intervertebral discs between vertebral bodies are examples of:
A. Synchondroses
B. Symphyses
C. Syndesmoses
D. Gomphoses
:: B. Symphyses – Intervertebral discs are symphyses (cartilaginous joints) that allow slight
movement and provide shock absorption between vertebrae.
