Study Notes
Head & Neck Muscles Overview
- Frontalis is located on the forehead, responsible for raising eyebrows and pulling the scalp forward.
- Temporalis is a lateral muscle of the skull that aids in closing the mandible, crucial for chewing.
- Occipitalis is situated at the posterior and inferior part of the skull and functions to pull the scalp backward.
- Orbicularis encircles the eyes, allowing for eye closure, such as winking motions.
- Zygomaticus is a facial muscle in the cheek area that elevates the corners of the mouth, contributing to smiles.
Chewing and Facial Expressions
- Buccinator is located in the cheeks; it tightens the cheeks, compresses them inward (essential for blowing air), and assists in the chewing process.
- Orbicularis Oris encircles the mouth, enabling mouth closure and lip protrusion, commonly used in kissing.
- Masseter is an important jaw muscle that primarily closes the mandible, functioning as a major muscle for chewing.
Neck Muscles and Functions
- Platysma covers the inferior part of the face and neck, responsible for depressing the lower lip and drawing the angles of the mouth downward.
- Sternocleidomastoid is a significant neck muscle that rotates and extends the neck, along with flexing movements.
