Final answer:
The eight carpal bones held together with ligaments form the 4) wrist, not the pelvis, skull, or foot. The wrist's carpal bones organize into proximal and distal rows and connect to the hand's metacarpal bones.
Step-by-step explanation:
The eight carpals held together with ligaments make up the wrist. These carpal bones are arranged in two rows of four: a proximal row and a distal row. The proximal carpal bones include the scaphoid, lunate, triquetrum, and pisiform. The distal row consists of the trapezium, trapezoid, capitate, and hamate bones. The carpals articulate with the metacarpal bones to form the base of the hand, which leads into the palm formed by the metacarpal bones themselves.
The pelvic girdle is not correct as it consists of the hip bones, sacrum, and coccyx, forming the pelvis. Moreover, the skull is made up of cranial and facial bones, and the foot consists of tarsals, metatarsals, and phalanges, which are different from the carpals of the wrist. Therefore, Option 4: Wrist is the accurate answer to what the eight carpal bones held together with ligaments make up.
