In frogs and toads, stomach eversion is accompanied by 'gastric grooming' with the right hand to wipe away vomitus6. We propose that rays' head-shaking during oral eversion fulfils a similar function, and rinses the stomach of persistent small particles and mucus. David W. Sims*, Paul L....
The effect of heart stimulation by vibrations (with the aid of electromagnetic vibrator) on the motor function of the stomach was studied in experiments on animals (frogs and dogs).doi:10.1007/BF00785968V. P. Riumin1. Perm Medical Institute, Perm, USSR ;...
Cooking science explains why and how food substances change while heated or cooled—such as why egg whites turn from clear to white when cooked, why meat browns, how proteins and carbohydrates function—and some chefs take this to the next level. Using syringes, centrifuges, liquid nitrogen ...
Although ice crystals form under the skin when frogs hibernate in the winter, a high concentration ofglucose occurring naturally in the frog's organs prevents the animal from freezing. Even when a deep freeze causes the frog's heart to stop beating and the frog to stop breathing, the body w...
not as numerous as that of adult frogs, displays histological traits that indicate a relevant (immunoreactive and ultrastructural properties, cellular diversity) and specific (surface location, relative abundance of open-type cells) role of local regulatory factors in amphibian larval gastric function.doi...
The transepithelial voltage and the rate of alkalinization (ASR) of an unbuffered gastric lumen perfusate was measured as a function of serosal (and mucosal) fluid composition. ASR was high (0.88±S.E. 0.09 μEq·cm 2 ·h 1 , n =11) during serosal bath perfusion with HCO 3 -Ringer...
