  1. gliding joint

  2. ball and socket joint

  3. hinge joint

  4. pivot joint
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The elbow joint functions as a hinge joint, allowing movement primarily in one plane (flexion and extension - bending and straightening). Hinge joints are like door hinges, permitting back-and-forth movement in a single axis. The knee is another example of a hinge joint, distinguishing it from ball-and-socket (hip/shoulder), pivot (neck), and gliding joints (wrist/ankle).

  3. expanded ileum

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The human pelvis is indeed remarkable for all these features: it has a deep concavity (the pelvic cavity) to protect abdominal organs, it is broad (for upright walking and birth canal), and the ilium is expanded (forming the familiar hip shape). These adaptations are crucial for bipedal locomotion and parturition.
