Select the incorrect match.

Options

A. Pectoral girdle - 4 bones
B. False ribs in humans that are not true- 8th to 10th
C. Palm bones in limbs - 5
D. Ankle bones in a limb - 7

Answer

To solve the question of selecting the incorrect match, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Identify the Pectoral Girdle**:
- The pectoral girdle consists of the scapula (shoulder blade) and the clavicle (collarbone).
- Total number of bones in the pectoral girdle: 2 (scapula + clavicle).

**Hint**: Remember that the pectoral girdle is made up of two specific bones.

2. **Examine the False Ribs**:
- In humans, false ribs are defined as those ribs that do not attach directly to the sternum.
- The pairs of false ribs are the 8th, 9th, and 10th pairs.
- Therefore, the statement regarding false ribs is correct.

**Hint**: False ribs are those that connect to the sternum indirectly.

3. **Check the Palm Bones**:
- The palm bones refer to the metacarpals.
- There are 5 metacarpal bones in the human hand.
- This statement is also correct.

**Hint**: Count the bones in your hand to remember the number of metacarpals.

4. **Analyze the Ankle Bones**:
- The ankle bones are referred to as tarsals.
- There are a total of 7 tarsal bones in the human ankle.
- This statement is correct as well.

**Hint**: Recall that the tarsals are the bones that form the ankle.

### Conclusion:
After analyzing all the statements, the incorrect match is the first statement regarding the pectoral girdle, which incorrectly states that it consists of four bones instead of two.

### Final Answer:
The incorrect match is: **Pectoral girdle - Four bones**.
