Scalp

1. EPICRANE

The Epicranium is a vast musculotendinous lamina that covers the vertex and the lateral faces of the skull, from the occipital bone to the eyebrow. It is formed by the occipital womb and the frontal womb and these are joined by an extensive intermediate aponeurosis: the aponeurotic galea.

Occipital Womb
Source: 2/3 lateral superior nuchal line of occipital bone and mastoid process
Insertion: Aponeurotic galea
Innervation: Posterior auricular branch of facial nerve
Action: Working with the front belly pulls back the scalp, raising the eyebrows and wrinkling the forehead.

* Front Belly
Source: It has no bone insertions. Its fibers are continuous with those of the procerus, corrugator and orbicularis of the eye.
Insertion: Aponeurotic galea
Innervation: Temporal Branches
Action: Working with the occipital belly pulls back the scalp, raising the eyebrows and wrinkling the forehead. Acting in isolation, it raises the eyebrows on one or both sides.

2. TEMPOROPARIETAL

The Temporoparietal is a vast, very thin blade.

Source: Temporal Fascia
Insertion: Lateral edge of the aponeurotic galea
Innervation: Temporal Branches
Action: Stretches the scalp and pulls back the skin of the temples. Combines with occipitofrontal to wrinkle forehead and widen eyes (expression of fear and horror).

3. APONEURTIC GEL

The aponeurotic galea lines the upper part of the skull between the frontal and occipital belly of the occipitofrontal.

Source: External occipital protuberance and supreme nuchal line of occipital bone
Insertion: Front. Each side receives the insertion of the temporoparietal
Innervation: The frontal and temporoparietal belly are supplied by the temporal branches, and the occipital belly by the posterior auricular branch of the facial nerve.
Action: Pulls back scalp by raising eyebrow and wrinkling forehead as an expression of surprise.

Eyelids

1. EYE ORBICULAR

This muscle bypasses the entire circumference of the orbit. It is divided into three parts: eyelid, orbital and lacrimal.
Source: Nasal part of the frontal bone (orbital portion), frontal process of the maxilla, posterior lacrimal crest (lacrimal portion) and the anterior surface and edges of the medial eyelid ligament (eyelid portion)
Insertion: Circles the orbit like a sphincter

Innervation: Temporal and zygomatic branches of the facial nerve
Action: Active closure of the eyelids

2. SURFACE CORRUGATOR

Source: Medial end of the superciliary arch
Insertion: Deep Skin Surface
Innervation: Temporal and zygomatic branches of the facial nerve
Action: Traction the eyebrow down and medially, producing vertical wrinkles on the forehead. Muscles of suffering expression.

Nose

1. NEXT

Source: Fascia lining the lower part of the nasal bone and the upper part of the lateral nasal cartilage
Insertion: Skin of the lower part of the forehead between the two eyebrows
Innervation: Buccal branches of the facial nerve
Action: Pulls down the medial angle of the eyebrow and causes the transverse wrinkles on the root of the nose.

2. NASAL (NOSE TRANSVERSE)

Source:

* Cross portion & #8211; Jaw above and lateral to the incisor fossa
* Alar Portion & #8211; Nose wing
Insertion:
* Cross portion & #8211; Back of the nose
* Alar Portion & #8211; Nose Summit Immediations
Innervation: Buccal branches of the facial nerve
Action: Nose Dilatation

3. SEPTEM DEPRESSOR

Source: Incisor fossa of the jaw
Insertion: Septum and dorsal part of the wing of the nose
Innervation: Buccal branches of the facial nerve
Action: Pulls down the wings of the nose, narrowing the nostrils

Ear

1. PREVIOUS HEARING

Source: Anterior portion of the fascia in the temporal zone
Insertion: Overhang in front of the helix
Innervation: Temporal Branches
Action: Pulls the ear flag forward and up

2. TOP HEARING

Source: Temporal zone fascia
Insertion: Flat tendon at the top of the cranial surface of the ear pavilion
Innervation: Temporal Branches
Action: Traces the ear flag up

3. AFTER HEARING

Source: Mastoid Process
Insertion: Lower part of the cranial surface of the shell
Innervation: Posterior auricular branch of facial nerve
Action: Pulls the ear flag back

Mouth

1. UPPER LIP LIFT AND NOSE WING

Source: Frontal process of the jaw
Insertion: It is divided into two fascicles. One fits into the greater alar cartilage and nose skin and the other extends to the upper lip
Innervation: Buccal branches of the facial nerve
Action: Dilates the nostril and raises the upper lip

2. UPPER LIP LIFT

Source: Lower margin of orbit above infraorbital, maxillary and zygomatic foramen
Insertion: Upper lip and nose wing
Innervation: Buccal branches of the facial nerve
Action: Raises the upper lip and takes it a little forward

3. MOUTH ANGLE LIFT

Source: Canine fossa (jaw)
Insertion: Mouth Angle
Innervation: Buccal branches of the facial nerve
Action: Raises the angle of the mouth and accentuates the nasolabial fold

4. Smaller Zygomatic

Source: Zygomatic bone malar surface
Insertion: Upper lip (between the upper lip lifter and the larger zygomatic)
Innervation: Buccal branches of the facial nerve
Action: Helps lift the upper lip and accentuate the nasolabial fold

5. Larger Zygomatic

Source: Zygomatic bone malar surface
Insertion: Mouth Angle
Innervation: Buccal branches of the facial nerve
Action: Pull the angle of the mouth back and up (laugh)

6. RISK

Source: Masseter Fascia
Insertion: Skin at Mouth Angle
Innervation: Mandibular and buccal branches of facial nerve
Action: Retracts mouth angle laterally (forced laughter)

7. LOWER LIP DEPRESSOR

Source: Oblique line of the jaw
Insertion: Lower lip integument
Innervation: Mandibular and buccal branches of facial nerve
Action: Pulling the lower lip straight down and laterally (expression of irony).

8. MENTONIAN

Source: Incisor fossa of the jaw
Insertion: Chin integument
Innervation: Mandibular and buccal branches of facial nerve
Action: Raises and protrudes out the upper lip and wrinkles the skin of the chin.

9. TRANSVERSE OF MIND

Not found in all bodies.
Source: Midline just below the chin
Insertion: Mouth Angle Depressor Fibers
Innervation: Mandibular and buccal branches of facial nerve
Action: Helps in depression the angle of the mouth

10. MOUTH ANGLE DEPRESSOR

Source: Oblique line of the jaw
Insertion: Mouth Angle
Innervation: Mandibular and buccal branches of facial nerve
Action: Depresses the angle of the mouth (expression of sadness)

11. MOUTH ORBICULAR

Not found in all bodies.
Source: Marginal part and lip part
Insertion: Rhyme of the mouth
Innervation: Buccal branches of the facial nerve
Action: Direct lip closure

12. BUFFINATOR

Important accessory muscle in chewing, keeping food under direct pressure from the teeth.
Source: External surface of the maxillary alveolar processes above the mandible
Insertion: Mouth Angle
Innervation: Buccal branches of the facial nerve
Action: Depresses and compresses the cheeks against the jaw and jaw. Important to whistle and blow.
