Which of the following is not a phase of gastric secretion?
enterogastric
What phase of the gastric secretion is chyme moved into the duodenum?
intestinal phase
What is the intestinal phase?
control of gastroc secretion is divided to cephalic phase, gastric phase and intestinal phase. Among these, intestinal phase means gastric secretion in stomach as a result of stimulation in intestine by food. when the food reaches the intestine it secrete gastrin and the hormone transports to stomach by circulation. amount of secretion in intestinal phase is smaller and slower than that of cephalic and gastric phase. by the way if substance like acid, lipid or any high osmotic solution entered intestine, duodenum, gastric secretion decreases this time. This is because of enterogastrone released from duodenum. there are also other hormones such as cholecystokinin and gastric inhibitory peptide. they inhibit the secretion in stomach.
What is cephalic phase of digestion?
it is triggered by the smell, taste, sight, or thought of food. parasympathetic impulses trigger gastric juice secretion.
What hormone regulates gastric secretion during the cephalic phase of digestion?
Gastrin, which is secreted by the enteroendocrine cells of the stomach. Gastrin stimulates the secretion of hydrochloric acid and pepsin; induces contraction of the lower oesophagus; mildly increases the motility of the GI tract; and relaxes the pyloric sphincter.
Of cephalic phase or celiac phase or plateau phase or intestinal phase or gastric phase which is not a phase of gastric regulation?
s phase
Fat in the duodenum stimulates which hormone?
The original answer posted was Cholecystokinin, which is actually a peptide hormone that is released to inhibit gastric mobility. But it is not the first hormone to be released when fat or food initially contacts the duodenum.When Fat enters the duodenum, this accounts for the third phase of gastric secretion, called intestinal phase. This phase accounts for 5% of the total secretory response. It begins when food leaves the stomach and enters the small intestine (duodenum). When the food first contacts the intestinal wall, it stimulates intestinal cells to release a hormone called, intestinal gastrin, that enhances gastric gland secretion.
What is the first phase after a stimulus in a muscle contraction?
Latent Phase
During the secretory phase of the menstrual cycle?
progesterone secretion is at its highest
What phase is between stimulus of a muscle and the shortening of the muscle?
belly
What causes the release of gastric juice during the gastric phase?
Entry of food into the stomach and distension of the stomach
Why is it only possible to induce an extrasystole during relaxation?
The cardiac muscle is incapable of reacting to any stimulus before approximately in the middle of phase 3. It will not react to a normal cardiac stimulus before phase 4.
