Bone related to skull is

Options

A. Coracoid
B. Arytenoid
C. Pterygoid
D. Atlas

Answer

To solve the question "Bone related to skull is", we need to analyze each of the options provided:

1. **Caricoid**:
- The caricoid bone, also known as the coracoid process, is located in the shoulder region. It connects the cranial edge of the sternum to the shoulder joint complex. Therefore, it is not related to the skull.

2. **Artenoid**:
- The artenoid bone is part of the larynx and is involved in the formation of dental enamel. It does not have any relation to the skull.

3. **Atlas**:
- The atlas is the first cervical vertebra (C1) that supports the weight of the skull. While it is associated with the skull in terms of supporting it, it is technically a vertebra rather than a bone of the skull itself.

4. **Pterygoid**:
- The pterygoid bone is a process that extends from the sphenoid bone of the skull. It forms part of the skull structure and is directly related to the skull.

After analyzing all the options, the correct answer is **C. Pterygoid**.

### Step-by-Step Solution:
1. **Identify the Options**: Look at the four options provided: Caricoid, Artenoid, Atlas, and Pterygoid.
2. **Analyze Each Option**:
- **Caricoid**: Not related to the skull; it’s in the shoulder region.
- **Artenoid**: Not related to the skull; it’s part of the larynx.
- **Atlas**: Supports the skull but is a cervical vertebra, not a skull bone.
- **Pterygoid**: Part of the skull, extending from the sphenoid bone.
3. **Select the Correct Answer**: Based on the analysis, the pterygoid bone is the only one that is directly related to the skull.

### Final Answer:
The bone related to the skull is **C. Pterygoid**.
