In human beings the cranium is formed by

Options

A. ten bones of which two are paired
B. eight bones of which two are paired
C. fourteen bones of which six are paired
D. eight bones of which three are paired

Answer

To answer the question "In human beings, the cranium is formed by," we need to identify the number of bones that make up the human cranium and how many of those are paired.

### Step-by-step Solution:

1. **Understanding the Cranium**: The cranium is the part of the skull that encloses and protects the brain. It is distinct from the facial bones.

2. **Counting the Cranial Bones**: The human cranium is composed of a total of **8 cranial bones**.

3. **Identifying Paired and Unpaired Bones**:
- Among these 8 bones, some are paired (meaning there are two of them), and some are unpaired (meaning there is only one of them).
- The paired bones are:
- **Parietal bones** (2)
- **Temporal bones** (2)
- The unpaired bones are:
- **Frontal bone** (1)
- **Occipital bone** (1)
- **Sphenoid bone** (1)
- **Ethmoid bone** (1)

4. **Summarizing the Bone Count**:
- Total cranial bones = 8
- Total paired bones = 4 (2 pairs: parietal and temporal)
- Total unpaired bones = 4 (frontal, occipital, sphenoid, ethmoid)

5. **Conclusion**: Thus, the correct answer to the question is that the cranium is formed by **8 bones of which 2 are paired**.

### Final Answer:
The cranium in human beings is formed by **8 bones of which 2 are paired**.
