|---|---|
| Action | movement accomplished by a muscle when the muscle fibers contract |
| Facial Paralysis | loss of action of the facial muscles |
| Insertion | end of the muscle that is attached to the more moveable structure |
| Muscle | type of body tissue that shortens under neural control, causing soft tissue and bony structures to move |
| Origin | end of the muscle that is attached to the least moveable structure |
| Skeletal Muscles | voluntary muscles, appear stiped microscopically (striated), many nuclei |
| What are the two cervical muscles? | sternocleidomastoid and trapezius |
| Sternocleidomastoid (SCM) | flexes or tilts the head... |
| Cardiac Muscles | involuntary, involving the heart, branched with 1-2 nuclei |
| Smooth Muscles | involuntary, in the walls of hollow organs and blood vessels, spindle, 1 nuclei |
| Arteries | carry blood away from the heart |
| Vein | carry blood to the heart |
| Where is the insertion for facial muscles | the skin |
| What can cause an inability to form facial expressions | damage to the seventh cranial/nerve |
| Masseter Muscle | muscle of mastication, one of the strongest muscles |
| Mastication | chewing |
| Epicranial Muscle | in the scalp region, raises eyebrows |
| Orbicularis Oculi Muscle | opens/closes eyelid |
| Corrugator Supercillii Muscle | medial wrinkle between eyebrows |
| Chemodenervation | botox |
| Procerus | pulls eyebrow medial end down as in a frown or squint |
| Dilator Naris | pulls down on nostrils in a flare/dilation |
| Compressor Naris | closing and compressing of nostrils |
| Orbicularis Oris Muscle | closes the lips, pursing the lips (kissing muscle) |
| Lip Incompetence | failure to provide a lip seal can affect the position of the teeth |
| Buccinator Muscle | muscle of mastication, quadrilateral muscle that forms the anterior part of the cheek or lateral wall within the buccal region |
| Pterygomandibular Raphe | tendinous band posterior to the most distal mandibular molar, spans between the mandibular ramus and the middle palate |
| Risorius Muscle | thine, in the oral region in a smiling or grimace |
| Levator Labii Superioris | broad and flat muscle, smiling/uplift (elvis muscle) |
| Zygomaticus Major Muscle | lateral to the minor |
| Zygomaticus Minor | elevates the upper lip (smiling) |
| Levator Anguli Oris Muscle | elevates the labial commisure (smilling) |
| Deppresor Anguli Oris Muscle | depresses the labial commisure (frowning) |
| Deppresor Labii Inferioris Muscle | depresses lower lip |
| Mentalis Muscle | raises chin |
| Platysma Muscle | raises neck skin |
| Are muscle of the ear paired? | yes |
| Anterior Auricular Muscles | arise from connective scalp tissue, run posterior to the anterior ear, pulls ears forward |
| Superior Auricular Muscles | raises the ear |
| Posterior Auricular muscles | pulls ears back |
| Are the scalp muscles paired? | yes |
| Platysma | the only neck muscle that affects facial expression |
| Corrugator | pulls up the eyebrow medially and down in a frown |
| Levator Palpebrae Superioris | raises the upper eyelid |
| Do the mouth muscles aid in mastication | yes |
| Muscles of mastication | temporalis, masseter, medial and lateral pterygoid, and the buccinator |
| Masseter | most powerful, elevates the mandible, originates from two areas on the zygomatic arch |
| Temporal Muscle | elevates and detrudes mandible, fan-shaped, originates from temporal fossa |
| Medial Pterygoid Muscle | elevates the mandible, attaches to the medial of the mandibular angle |
| Lateral Pterygoid Muscle | opens mandible, fibers that run primarily horizontally |
| Suprahyoid | above the hyoid; includes the digastric, mylohyoid, geniohyoid, and stylohyoid |
| Infrahyoid | below the hyoid; includes the omohyoid, sternohyoid, sternothyroid, and thyrohyoid |
| Digastric | retrudes the mandible, can lift the hyoid bone and pulls up the larynx, and helps pull the mandible down |
| Mylohyoid | forms the mouth floor |
| Geniohyoid | depresses mandible or elevates the hyoid |
| Stylohyoid | pulls hyoid up and back |
| Omohyoid | brings up the hyoid bone |
| Sternohyoid | pulls hyoid |
| Sternothyroid | pulls larynx down |
| Thyrohyoid | lifts thyroid/larynx or depresses hyoid |
