| prevent excessive opening | sphemandibular ligament (lingula of mandible) stylomandibular angle of mandible |
| muscle responsible for protrusive and lateral movements | lateral pterygoid |
| what nerves innervate max 1st molar | MB root-middle superior alveolar, everything else PSA |
| sublingual gland | mucous cells mostly!!, rivian ducts |
| where are von ebner's glads | circumvallate papilla, main fuxn to rinse food off taste budes |
| Wharton's duct | submandibular duct, exits underneath frenula of tongue |
| what is the articular disc made of | fibrocartilagenous tissues (NOT HYALINE CARTILAGE) |

| NO2 with asthma patients | not a problem, |
| esters metabolized | blood stream- by cholinesterases |
| best pH for anesthesia | above 7 -non ionize/base form of anesthesia best at crossing membranes. lipid solubility, diffusibility, protien binding (more binds to protien the longer will act) |
| where does NO2 act | central nervous system (reticular activating system and limbic system), be careful of diffusion hypoxia, max to give is 70% and 30% O2 |
| what nerves do anesthetic affect 1st? | Na channels of small, myelinated fibers (pain and temp) then loos |
| when get lygenospasm and how treat it | rarely with ketamine, get blood and saliva around vocal cords, cause cords to close can't get air in. tx with positive pressure o2 and succinylcholine ie skelatal muscle relaxant |
| what determines if bones get displaced | line of fracture- if unfavorable line of fracturehtan lateral ptyerygoid diplaces condyle anteromedially, temporalis, masseter and medial pterygoid attached to ramus pull mandible upward, digastric, geniohyoid, genioglossus, and mylohuoid postrior inerior force |
| 4 types of mandibular fractures | simple, compound (exposed to oustide environment common to get ifxn), comminuted (multople fractures along a single bone) greenstick (close grafture extend only though cortical portion doesn't completely fracture bone most ocmmonly seen in kids) |
| how does bone heal | by primary-they are touching, or secondary- hemorrhage get clot then callus formation, then fuxn reconstruction takes 2-3 years |
| what movements help depress the mandible | digastrix, mylohyoid,geniohyoid LATERAL PTYERGOID |
| elevate madible | medial ptyergoid, masseter, and temporalis |
| protrode mandible | lateral pterygoid |
| what are subperiosteal implants | they form to ride fo the bone |
| root form implants | another name for endoosseuous implants |
| minumum intertooth distance for an implant | 10 mm |
| what is the masticator space | comprised of masseteric, pterygomandibular and temporal spaces since they are all bounded by muscles of mastication, most definitive clinical sign is trismus |
| need traction infxn from inferior alveolar block do | ptergomandibular space initially |
| mubmandubular space | is submaxillary, submetnal and sublingual spaces |
| how to treat dentigerous cyst in an eruptin kid | uncover the crown and keep it exposed |
| what in the trendelenburg position, when it is used | body staright head is facing ground at 45 degree angle, used for treating anaphyactic shock- don't do if head injury |
