What does gastrin stimulate?
Gastrin is a hormone secreted by the stomach which stimulates the secretion of hydrochloric acid, increase motility, and stomach emptying.
How do sympathetic and parasymphatetic activity affect gastric secretion?
Sympathetic activity inhibits gastric secretion by causing vasoconstriction of blood vessels in the stomach lining. Parasympathetic activity stimulates gastric secretion by increasing blood flow and activating gastric glands, leading to increased production of stomach acid and digestive enzymes.
What cell type secretes gastrin?
G cells in the stomach lining secrete gastrin hormone. This hormone helps in the regulation of gastric acid secretion and motility in the stomach.
DO peptides in the the stomach inhibit secretion of gastrin?
Yes, peptides in the stomach can inhibit the secretion of gastrin. When protein digestion occurs, the presence of peptides stimulates the release of gastric acid, which in turn leads to a feedback mechanism that reduces gastrin secretion. This regulation helps maintain appropriate levels of gastric acid and ensures that the digestive process functions efficiently. Thus, the presence of peptides acts as a signal to modulate gastrin release as part of the digestive feedback loop.
What effect would cutting the vagus nerve branch that innervates the stomach on gastric function?
Reduce gastric acid secretion. Also causes faster emptying of liquids from the stomach, but delayed emptying of solids from the stomach. Source: medical doctor

What hormone stimulates gastric acid?
a polypeptide hormone,
What increases gastric acid secretion?
Gastric acid secretion can be increased by factors such as the presence of food in the stomach, the release of gastrin hormone, histamine stimulation, certain medications like NSAIDs, stress, and smoking.
