|
Definition
| Supplies all mandibular teeth. Also has small branch that supplies the mylohyoid muscle. |
|
|
Term
|
Definition
| Exits the mental foramen and supplies the lingual gingiva and mucosa(lip) of the anterior mandible. |

Term
| What are the types of papilla on the tongue? |
|
Definition
Fungiform: found in anterior 2/3, round, raised, few taste buds
Filiform: Found in the anterior 2/3 of tongue, hairlike structures, provide tactile sensations.
Vallate: Posterior 1/3 of tongue, form a V shape pointing towards the back, 13 elevations. contain many taste buds
Foliate: not very common in humans, well developed in animals |

Inserition: Angle of the mandible on the medial side |
|
|
Term
| Describe the Temporomandibular Joint |
|
Definition
| The TMJ joint is a bilateral synovial joint, that is made up of two individual hinges. The condyloid process sits in the glenoid or mandibular fossa and rotates with the articular disk inbetween. The disk is made of collagenous fibers and sits between the glenoid fossa and the articular eminence, it has a posterior and anterior band which are innervated and an intermediate zone, which is not innervated. Synovial fluid is found above and below the disk and forms the upper and lower synovial cavities. |
|
|
Term
|
Definition
| Occurs when the mouth is open too far and cannot close. Is a result of the articular disk moving anterior to articular eminence, the muscles of mastication then pull up, locking the jaw in place. To fix, place pressure on posterior mandibular teeth and press down and back. |
|
|
Term
|
Definition
| Grinding of teeth which primarily occurs during sleep. May cause permanent wear to teeth and can cause soreness in the TMJ joint. Can be treated by wearing a plastic night guard. |
|
|
Term
|
Definition
| Can be caused by the disk being pulled too far forward and the posterior band getting caught inbetween the head of the condyle and the articular eminence. |
