a 35 year old healthy financial advisor arrives at a fancy restaurant. When getting there he relizes that the wait is long but decides to stay because the food came highly recommended. Once he sits down he feel like ordering steak, but he promised himself that he would only eat salad. He orders a large salad with no dressing on it and he eats several dinner rolls with it. He is expected to be full but for some reason is not. Which one of the following circumstances would explain his lack of satisfaction ?
A Acetylcholine release
B Lack Of gastric inhibitory peptide release
C Histamine release
D Lack of CCK realease
E Lack of Secretin release
I expect an explanation....
this is the second of two q I have put up in the last hour, if you havent answered the other, make sure you do!!

Very good guys, this was point in the kaplans med essentials book. CCK and calcitonin have been known to suppress hunger. Calcitonin does it by and unknown mechanism and is unimportant in this case. Food, particularly fats, and aminoacids cause the release of CCK from the I cells in the small intestine. This will cause the normal contration of the gallbaldder, increase in secretion of HCO3 and pacreatic enzymes, relaxation of the sphicter of ODDI. There are two types of CCK receptors, CCK a - found in periphery, CCK b- found in the brain. Both when stimulated will decrease appetite.
I thought this was some interesting knowledge as it isnt in kap lecture notes, I have heard many fat people say " I only at a salad...but then I was still hungry...so I ate some more. Salad never fills me up. " LoL now you now there may be some truth to this and its just not a fat person being hungry all the time  .
