Head Flashcards
Masseter Origin Insertion
Maxillary process of the zygomatic bone to ramus of the mandible
Masseter Arterial, Innervation
Mandibular nerve (V3), Masseteric artery
Masseter Function
Elevation of the mandible (closes the mouth).
Digastric Origin Insertion
mastoid process of the temporal bone to intermediate tendon (Hyoid bone )
Digastric Arterial, Innervation
Vertebral artery and occipital artery, digastric branch of the facial nerve
Digastric Function
Depresses the mandible and elevates the hyoid bone.
Buccinator Origin Insertion
Alveolar process of maxilla to the angle of the moith
Buccinator Arterial, Innervation
Buccal branches of the facial nerve and Buccal artery
Buccinator Function
Compresses Cheek (Pulls the cheek inwards against the teeth, preventing accumulation of food in that area.)
Orbicularis oculi Origin Insertion
Medial Palpebral Ligament and frontal bone to Lateral Palpbral Raphe
Orbicularis Oculi Arterial, Innervation
Facial nerve (Temporal and zygomatic branches)
maxillary, superficial temporal, facial and ophthalmic arteries.
Orbicularis Oculi Function
Closes the eyelids (tight), drainage of tears.
What muscle closes the eyelids and assists in pumping the tears from the eye into the nasolacrimal duct system
Orbicularis Oculi
Temporalis Origin Insertion
Temporal fossa of the skull to the coronoid process of the mandible.
Temporalis Arterial, Innervation
