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.
