Questions: Which of the Following is NOT True of the Bones of the Hand? Which of the following is NOT true of the bones of the hand? Multiple Choice The carpals are arranged in 2 rows of 4 bones each. The hand contains a single metacarpal for each digit. All 5 digits of the hand contain 3 phalanges. All of these are true of the bones of the hand. The metacarpals articulate with the proximal phalanges.

The answer is the third one: All 5 digits of the hand contain 3 phalanges.

Explanation for each option:

1. The carpals are arranged in 2 rows of 4 bones each.
   This statement is true. The carpal bones in the wrist are indeed arranged in two rows, with four bones in each row.

2. The hand contains a single metacarpal for each digit.
   This statement is true. Each digit of the hand has one metacarpal bone, making a total of five metacarpals.

3. All 5 digits of the hand contain 3 phalanges.
   This statement is not true. While four of the digits (index, middle, ring, and little fingers) have three phalanges each (proximal, middle, and distal), the thumb only has two phalanges (proximal and distal).

4. All of these are true of the bones of the hand.
   This statement is incorrect because, as explained, not all five digits contain three phalanges.

5. The metacarpals articulate with the proximal phalanges.
   This statement is true. The metacarpal bones articulate with the proximal phalanges of the fingers.

In summary, the statement that "All 5 digits of the hand contain 3 phalanges" is not true, as the thumb only has two phalanges.
