What is this region

Back 30

Orbicularis oculi Orbital part originates from the medial part of the medial palpebral ligament, the nasal part of the frontal bone, and the frontal process of the maxilla. The fibers encircles the eye and inserts into the lateral palpebral raphe and frontalis muscle, corrugator muscle, and the tarsi. The palpebral portion also arises from the medial palpebral ligament and lacrimal crest and laterally the fibers of both lid interdigitate at the lateral palpebral raphe.These muscles are responsible for closing the eye.

Levator labii superioris (Muscle of the mouth)

Front 32

Back 32

levator labii superioris alaque nasi:
originate from the frontal process of the maxilla and inserts in the upper lip and alar cartilage of the nose. The name of this muscle

Front 33

Back 33

The zygomaticus major arises from the posterior and lateral part of the zygomatic bone below the orbicularis oculi and passes obliquely downwad and forward to the corner of the mouth where it attaches to skin and mucosa . The zygomaticus minor originates from the zypomatic bone either below or deep to the orbicularis oculi and runs toward the mouth running parallel and above the zygomaticus major to insert into the upper lip just medial to the corner of the mouth.(Muscle of the mouth

Front 34

5

Back 34

orbicularis oris surrounds the mouth so it actually can be considered with the upper and lower mouth group and takes origin from other facial muscles in the maxilla, the nasal septum and the mandible and inserts into the dermis of lips and surrounding muscles. This muscle closes, purses, and protrudes the lips.

Back 35

LEVATOR ANGULI ORIS

Front 36

1

Back 36

mentalis originates from the mandible near the rooth of the incisor and passes downward to insert into the skin of the chin

Front 37

2

Back 37

The depressor labii inferioris originates from the front of the mandible and passes upward in front of the mental foramen. It takes origin deep to the depressor anguli oris. It is quadrangular in shape and runs medial to the depressor anguli oris

Front 38

3

Back 38

The depressor anguli oris arises from the anterior portion of oblique line and side of the body of the mandible at the level of the canine, premolar and first molar and converges to the corner of the mouth where it is partly inserted into skin and also the upper part of the orbicularis oris. It has the shape of a broad-based triangle

Front 39

Where does the buccinator originate?

Back 39

pterygomandibular raphe and the alveolar arches

Front 40

The buccinator inserts into what?

Back 40

inserts in the dermis of the lips and the surrounding muscles of the mouth. This muscle compresses the cheek and is the most lateral muscle of the cheek.
