Which of the following is correct regarding structure and bone count "unilaterally"?Group of answer choices28 phalanges7 carpals8 tarsals7metacarpals

Break Down the Problem

1. Identify the total bone counts in the human hand and foot for comparison.
2. Understand the definition of "unilateral" as it pertains to this question.
3. Evaluate each answer choice against the known counts.

Relevant Concepts

1. Bone Structure in the Hand:

   • Phalanges: 14 (3 in each finger, 2 in the thumb) for one hand.
   • Carpals: 8 total for one hand.
   • Metacarpals: 5 total for one hand.

2. Bone Structure in the Foot:

   • Tarsals: 7 total for one foot.
   • Phalanges: 14 (similar structure to the hand).
   • Metatarsals: 5 total for one foot.

Analysis and Detail

1. Phalanges: For one side (unilateral), the count is 14.
2. Carpals: For one side, the count is 8.
3. Tarsals: For one side, the count is 7.
4. Metacarpals: For one side, the count is 5.

Verify and Summarize

Now, let’s verify the counts against the choices given:

• 28 phalanges: Incorrect as unilateral is 14.
• 7 carpals: Incorrect as unilateral is 8.
• 8 tarsals: Incorrect as unilateral is 7.
• 7 metacarpals: Incorrect as unilateral is 5.

Final Answer

None of the choices correctly represent the unilateral bone counts. The correct unilateral counts are:

• Phalanges: 14
• Carpals: 8
• Tarsals: 7
• Metacarpals: 5
