Identify the sinus cavities of the skull.
Frontal, ethmoid, maxillary, sphenoid all sinuses
Name the bones that form the four walls of the orbit
Roof: frontal bone, lesser wing of sphenoid b.
Medial: lacrimal and ethmoid
Floor: maxilla and zygomatic
Lateral: greater wing of sphenoid b. And zygomatic
Name the attachments, function, and innervation of the buccinator m.
Attachments: from alveolar processes of the maxilla and mandible, pterygoid hamulus, and pterygomandibular raphe to the buccaneers angle
Function: compresses cheek
Innervation: buccal branch of the facial n.
Name the attachments, function, and innervation of the depressor anguli oris.
Attachments: from mandible to buccal angle
Function: depresses buccal angle laterally
Innervation: buccal and mandibular branch of facial n.
Name the attachments, function, and innervation of the frontalis m.
Attachments: from the superficial fascia of the eyebrows to the epicranial aponeurosis
Function: protraction the scalp or elevates eyebrows and nose
Innervation: temporal branch of facial n.
Name the attachments, function, and innervation of the levator labii superioris m.
Attachments: from the inferior orbital margin to the lateral aspect of the upper lip
Function: raises and everts upper lip
Innervation: buccal and zygomatic branches of facial n.
Name the attachments, function, and innervation of the nasalis m.
Attachments: from maxilla lateral and interior to the nasal notch to the bridge and ala of the nose
Function: transverse fibers compress and alar fibers widen the nasal aperture
Innervation: buccal branch of facial n.
Name the attachments, function, and innervation of the orbicularis oculi m.
Attachments: from orbital margin and medial palpebral ligament to superficial fascia of the eyelid
Function: a palpebral sphincter (closes eyes)
Innervation: temporal and zygomatic branches of facial n.
Name the attachments, function, and innervation of the masseter m.
Attachments: from the zygomatic arch to the angle of the mandible and lateral aspect of the ramus.
Function: elevation, protraction, and retraction (deep fibers) of the mandible
Innervation: mandibular n.
Name the attachments, function, and innervation of the temporalis m.
Attachments: temporal fossa to the coronoid process and anterior border of the ramus of the mandible
Function: elevation and retraction (posterior aspect of the muscle) of the mandible
Innervation: mandibular n.
Name the attachments, function, and innervation of the lateral pterygoid m.
Attachments: infratemporal surface of the sphenoid and lateral surface of the lateral pterygoid plate to neck of mandible and TMJ disc
Function: depresses mandible, protraction and acts with ipsilateral medial pterygoid to rotated mandible to produce side-to-side movements during chewing
Innervation: mandibular nerve (v3)
Name the attachments, function, and innervation of the medial pterygoid m.
Attachments: medial surface of lateral pterygoid plate and adjacent maxilla to medial aspect of angle of mandible
Function: elevation of mandible and acts with ipsilateral lateral pterygoid to rotate mandible during trituration of food
Innervation: mandibular n.
Name the attachments, function, and innervation of the platysma
Attachments: lower border of mandible to superficial fascia of skin of neck overlying clavicle
Actions: wrinkles the anterior nuchal skin
Innervation: cervical branch of the facial n
