Answer

To determine how many bones are present in the human skull, we can break down the skull into its main components: the cranium, the facial bones, and the auditory bones.

### Step-by-Step Solution:

1. **Identify the Components of the Skull**:
- The human skull is divided into two main parts: the cranium and the facial bones.

2. **Count the Bones in the Cranium**:
- The cranium consists of 8 bones:
- Ethmoid
- Sphenoid
- Frontal
- 2 Parietal bones
- 2 Temporal bones
- Occipital bone
- Total for cranium = 8 bones.

3. **Count the Bones in the Facial Region**:
- The facial bones consist of 14 bones:
- 2 Nasal bones
- 2 Lacrimal bones
- 2 Inferior nasal conchae
- 2 Maxilla (upper jaw)
- Mandible (lower jaw) - 1 bone
- 2 Palatine bones
- 2 Zygomatic bones (cheekbones)
- Vomer - 1 bone
- Total for facial bones = 14 bones.

4. **Count the Auditory Bones**:
- There are 6 auditory bones in total (3 in each ear).

5. **Calculate the Total Number of Bones in the Skull**:
- Total bones in the skull = Bones in cranium + Bones in facial region + Auditory bones
- Total = 8 (cranium) + 14 (facial) + 6 (auditory) = 28 bones.

6. **Conclusion**:
- Therefore, the total number of bones present in the human skull is 28.

### Final Answer:
The total number of bones in the human skull is **28**.
