Physiology
Gastrin is a hormone released by G cells in the gastric antrum in response to the presence of food, especially protein. It acts on parietal cells in the gastric glands, stimulating them to produce and secrete hydrochloric acid (HCl) and intrinsic factor, which is essential for vitamin B12 absorption. Gastrin is a critical component of the gastric phase, which is responsible for the bulk of gastric acid secretion.

ProsthodonticsAccording to Monson's spheric theory of occlusion, each cusp and incisal edge conforms to a segment of a sphere, 8 inches in diameter, with its center in the region of the glabella. The glabella is the area of skin and underlying bone between the eyebrows and above the nose. This theory is an ideal model used as a reference in dental restorative procedures, particularly in prosthodontics and orthodontics.
