All but one of the following bones are found in the human appendicular skeleton. Select the exception.

Options

A. Finger bones
B. Upper arm bone
C. Jaw bone
D. Ankle bones

Answer

To solve the question regarding which bone is not part of the human appendicular skeleton, we can follow these steps:

### Step 1: Understand the Appendicular Skeleton
The appendicular skeleton consists of the bones of the limbs (arms and legs) and the girdles (shoulder bones and pelvic bones) that attach the limbs to the axial skeleton.

### Step 2: Identify the Bones Listed
We need to analyze the bones mentioned in the question:
1. Finger bones
2. Upper arm (humerus)
3. Jaw bone
4. Ankle bones

### Step 3: Classify Each Bone
- **Finger bones**: These are part of the hand, which is included in the appendicular skeleton.
- **Upper arm (humerus)**: This is the bone of the upper arm, also part of the appendicular skeleton.
- **Jaw bone**: This is part of the skull, which is part of the axial skeleton, not the appendicular skeleton.
- **Ankle bones**: These are part of the foot, which is included in the appendicular skeleton.

### Step 4: Identify the Exception
From the classification, the only bone that does not belong to the appendicular skeleton is the **jaw bone**.

### Conclusion
The exception to the bones found in the human appendicular skeleton is the **jaw bone**.
