Buccinator

Lies deep and slightly anterior to the massester

Temporalis

Lies on the temporal bone of the skull

Labii means?

Lips

Masseter

The parotid duct from the parotid gland lies on the surface of that muscle?

Masseter

The sternocleidomastoid has three points of attatchment

Mastoid process of skull Clavicle Manubrium of sternum

Identify the muscle that lies on the mental protuberance

Mentalis

Name the muscle that is located in the center of the mentis region

Mentalis

What is the name of the muscle that covers the superficial area of the mental protuberance?

Mentalis

Name the muscle that makes up the entire floor of the mandible

Mylohyoid

Levator labii superioris alaeque nasi

Risorius

Name the most vertical muscle on the anterior side of the neck that lies deep to the platysma

Sternocleidomastoid

Name the muscle that inserts on the clavicle and manubrium of the sternum

Sternocleidomastoid

Scalene

There are 3 of these muscles in the neck, You can find these if you start at the distal end of the sternocleidomastoid in the clavicle region and go three muscles posterior.

Mentalis

This muscle is in the center of the mandible lying on the mental protuberance

Masseter

This muscle lies on the ramus of the mandible and inserts on the mandible

Diagastric

Two tubular shaped muscles lying on the inferior surface of the mylohoid

which zygomaticus muscle is the most superior?

levator labii superioris alaeque nasi

Occipitalis

lies on the occipital bone of the skull

levator labii superioris alaeque nasi

originates at the medial corner if the orbit of the eye it inserts in the area of the ala of the nose and upper lip

Platysma

the most superficial muscle of the neck, extends from the clavicle to the mandible

Splenius

there are several, but in the neck area we study the one that is posterior and superior to the lavator scapulae

Masster
