1) abnormal increase in BP in healthy person results in increased number of impulses travelling to heart over which nerve? ans vagus

why not sympathetic nerves?
2)which structure glycoprotein assembled for extracellular use.... ans is golgi
why not RER

3)muscular contraction result in displacement of left condyle in which area?
ans is infratemporal
why not middle ear cavity or maxillary sinus
4)swelling at angle of mandible and lateral neck most likely resulted from deflection of exudates by which structure?
ans is
mylohyoid ..........why not hyoglossus ,buccopharyngeal fascia.pterygomand raphe
5)muscle not in posterior triangle of neck.....ans sternohyoid.........why not ant belly of omohyoid

lymphatic fluid from infected tooth 32 drains in ..
buccal,submental,submand,sublingual,deep cervical....ans deep cervical node..

1) abnormal increase in BP in healthy person results in increased number of impulses travelling to heart over which nerve? ans vagus
: abnormal BP increae--> increase Parasymp. still to slow heart and bring BP back to normal (mediated through baroreceptors- i.e., carotid sinus)

why not sympathetic nerves?
2)which structure glycoprotein assembled for extracellular use.... ans is golgi
why not RER
Protein component synthesized in rER, Glucosyl and other residues + Modification in Golgi (some sugars added in rER with N-linked oligosacc)

3)muscular contraction result in displacement of left condyle in which area?
ans is infratemporal
why not middle ear cavity or maxillary sinus
Condyle not in middle ear cavity or maxilarry sinus

4)swelling at angle of mandible and lateral neck most likely resulted from deflection of exudates by which structure?
ans is
mylohyoid ..........why not hyoglossus ,buccopharyngeal fascia.pterygomand raphe
comes from knowledge of muscle attachments, fascial layers, and space anatomy

5)muscle not in posterior triangle of neck.....ans sternohyoid.........why not ant belly of omohyoid

ant omohyoid crosses posterior triangle; subdivides post triangle

thanks a lot.........
