**Diagram Title: Head Muscles**

This educational diagram presents the lateral view of the head and neck muscles, with illustrative highlights of specific muscle regions. It includes two primary sections labeled as A and B. Below is the detailed transcription and explanation of the diagram:

1. **Buccinator**
2. **Constrictor pharyngis superioris**
3. **External Pterygoid**
4. **Frontalis**
5. **Internal Pterygoid**
6. **Masseter**
7. **Occipitalis**
8. **Orbicularis oculi**
9. **Orbicularis oris**
10. **Platysma**
11. **Pterygomandibular raphé**
12. **Quadratus labii inferioris**
13. **Quadratus labii superioris**
14. **Sternocleidomastoideus**
15. **Temporalis**
16. **Triangularis**
17. **Zygomaticus**

**Diagram Sections:**

- **Section A (Left View):** Depicts a side view of the skull, showing the frontal and occipital muscle regions. 
  - Numbers correlate to specific muscles and their locations on the skull, highlighting frontal, temporal, and masseter muscle regions in orange.

- **Section B (Right View):** Provides a detailed view of muscles in the face and neck.
  - Key muscles such as the zygomaticus and constrictor pharyngis superioris are highlighted, showing their anatomical position or action orientation.
  - The sternocleidomastoideus is shown extending from the skull base to the clavicular region.

**Muscle Highlights:**

- The **frontalis** and **temporalis** are significant for facial expressions and jaw movement.
- **Masseter** is essential for mastication.
- Muscles around the mouth and eyes such as the **orbicularis oculi** and **orbicularis oris** facilitate actions like blinking and puckering.

This diagram is a useful resource for understanding the anatomy and function of head and neck musculature.
