Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.

Name the Muscles of Mastication   1.Temporalis 2.Masseter 3.Medial pterygoid 4.Lateral pterygoid.  
A:Elevates/closes mandible. O: Zygomatic arch. I: mandible- lateral surface of angle, ramus. N: Trigeminal, V.   Masseter  
A: Elevates/closes mandible, works with another muscle. O: medial surface of lateral pterygoid plate of sphenoid. I: medial surface of angle of madible. N: Trigeminal, V.   Medial (internal) Pterygoid  
A: Depressor/opener of mandible; protrudes mandible; permits side-to-side movement of mandible. O: Great wing of sphenoid and lateral surface of lateral pterygoid plate. I: Neck of condyle process of mandible and TMJ. N: Trigeminal, V   Lateral (external) Pterygoid  
A:Elevates/closes mandible and retracts mandible. O: Temporal fossa. I: coronoid process of mandible. N: Trigeminal, V. Can feel bulge when clench jaw. Cause of some headaches.   Temporalis  
Muscle(s) that elevates or close the mandible   Temporalis, Masseter, Medial (internal) pterygoid.  
Muscle(s) that retracts mandible   Temporalis  
Muscle(s) that depresses or open mandible   Lateral (external) pterygoid (also anterior belly of digasrtric, mylohyoid, geniohyoid)  
Muscle(s) that protrudes mandible   Lateral pterygoid  
muscle(s) that permits side-to-side movement of mandible   Lateral pterygoid  
Name the Outer circular (horizontal) muscles of the pharynx.   - Superior constrictor - Medial constrictor - inferior constrictor  
Name the inner longitudinal (vertical) muscles of the pharynx.   - Salpingopharyngeous - Stylopharyngeous - Plaltopharyngeous  
Muscle that forms the nasopharynx and oropharynx. Aides in swallowing by propelling the bolus and helps close the VP port.   Superior Pharyngeal Constrictor  
Muscle that is partially made up of the cricopharyngeous.   Inferior Pharyngeal Constrictor  
Muscles that work together for rotary chewing.   Medial and lateral pterygoids  
Which nerve innervates the muscles of mastication?   CN V- Trigeminal  
Name the cranial nerves important for innervating the muscles of swallowing.   CN V- Trigeminal CN VII- Facial CN IX- Glossopharyngeal CN x- Vagus CN XII- Hypoglossal  
Which group of muscles contribute to structure and elevate the larynx during swallow?   Suprahyoid Muscles: Mylohyoid, Digastric, Geniohyoid, stylohyoid,  
Which muscle is fan-shaped and known for making the floor of the mouth (FOM)?   Mylohyoid (while geniohyoid is the "table runner")  
Which muscles are responsible for big movements of the tongue?   Extrinsic lingual muscles: Genioglossus, Hyoglossus, Styloglossus, Palatoglossus  
Which muscle has 2 bellies and a bend in it? One belly pulls hyoid up and forward before swallowing, while the other belly pulls hyoid back after swallowing.   Digastric  
Which extrinsic lingual muscle is also known as the anterior faucil pillar?   Palatoglossus  
Which muscles are responsible for velar movement?   Velar muscles: Levator Veli Palatini, Musculus Uvulae, Palatoglossus, palatopharyngeous  
Which muscles is the largest velar muscle; most responsible for velar elevation?   Levator Veli Palatini  
Which velar muscle is the pressure equalizer- regulates the eustachian tube?   Tensor Veli Palatini  
What muscles are responsible for precise movements of the tongue?   Intrinsic tongue muscles: - superior longitudinal muscle - inferior longitudinal muscle - transverse muscle - verticle muscle  
Which muscles are responsible for movement of the lips and cheeks?   Muscles of the face: -Obicularis oris -zygomaticus minor -Lavator labii superior -Zygomaticus major -Levator anguli oris -Depressor labii inferior -Mentalis -Risorius -Buccinator  
Which muscle flattens the cheek and holds food in contact with teeth?   Buccinator
