Head Muscles

The Occipitofrontalis muscle originates from the Epicranial Aponeurosis, Occipital bone, and mastoid process, inserts into the skin above the eyebrows, and is responsible for raising the eyebrows and drawing the scalp posteriorly. The incorrect answers describe the origin, insertion, and action of other muscles, such as the Orbicularis oris, Trapezius, and Serratus anterior.

The Orbicularis Oris is a muscle around the mouth responsible for closing or protruding the lips, often associated with making a 'duck face'. The muscle is not related to forehead, neck, or upper back muscles as mentioned in the incorrect answers.

The correct answer provides the detailed information about the origins, insertions, and actions of both Zigomaticus Minor and Zigomaticus Major muscles. The incorrect answers do not accurately describe the specific details of these muscles, leading to confusion for the question taker.

The buccinator muscle is responsible for compressing the cheek, not for rotating the head, flexing the arm, or extending the leg.

The Mentalis muscle is responsible for bringing the lower lip up and out, as well as pulling the skin of the chin up (pouting). It is not involved in raising eyebrows, flexing the neck forward, or extending the elbow joint.

The Masseter muscle is responsible for closing the mouth by elevating the mandible. Its origin on the maxilla and zygomatic arch, along with its insertion on the angle of the ramus of the mandible, allows it to perform this action effectively.

The Temporalis muscle originates from the temporal bone, inserts on the coronoid process and ramus of the mandible, and is responsible for closing the mouth.

The sternocleidomastoid muscle is a neck muscle that plays a key role in head movement. Its origin on the sternum and clavicle, insertion on the mastoid process and occipital bone, and actions of flexing and extending the head are distinct features that differentiate it from the incorrect answers provided.
