The distal interphalangeal joints of the foot are described as which of the following?

• A. Joints between toe bones, farther from the body
• B. Side branch ligaments between hand bones and fingerbones
• C. Plantar calcaneonavicular ligament
• D. Inferior pubic ligament

Answer: (A)

The key idea is the location of the distal interphalangeal joints within the toes. These joints are the ones at the tip of each toe, between the middle and distal phalanges, and they sit farther from the body's center (distal). That makes them the joints between toe bones that are closest to the far end of the digit, functioning mainly as hinge joints to allow bending of the toe tip.

The other options point to structures that aren’t joints of the toes: a ligament described as a side branch between hand and finger bones isn’t a standard anatomical term for these joints; the plantar calcaneonavicular ligament is a separate ligament supporting the arch, not a joint; and the inferior pubic ligament is in the pelvis, not in the toes.
