micro decks says that..
in supraging plaque..
gram +ve anerobic facultative cocci. streptococcus sanguis, actinomycosis naeslundii and viscosus predominate.
as this plaq ages , vibrio, spirochetes and gram -ve bacteria predominate.

subging plaque..attached or loose, apithelium associated.
as pocket forms gram -ve anerobic rods

microflora of healthy gingival sulcus is?

gram -ve anerobic rods and fusobacteria
gram +ve cocci and filamentous bacteria
gram+ve facultative rods and spirochetes

so acc to the q,it's asking about the subgingival area right? and the decks says gram negative rods predominate there....its confusing still..anybody pls clear it out 😕

thanks docaspra for the answer

which of the following describes the effect of a drug that inhibit renal carbonic anhydrase?
a it decreases urea clearance
b it increases tm for glucose
c it increases the affinity of the urine
d it decreases sodium reabsorption in the proximal tubule (ans)

can somebody explain this

the answer is correct.

carbonic anhydrase is worling on the prox. tubules.. the result of its action is hco3- and H+.. this H+ is exchanged with na+ ( secondary active antiport ) h+ out na+ in.

if u block the enzyme--no production of h+ no exchange.

motor nucleus of trigeminal nerve. ans
mesencephalic nucleus is involved with jaw reflexes but it is sensory so no control over muscles. and nucleus ambiguus is for laryngeal and pharyngeal uscles
