In anatomy, the<unk>  is a type of cell in the stomach that secretes<unk> astrin. It works in conjunction with<unk> astric chief cells and parietal cells.<unk> s are found deep with the<unk> astric<unk> lands of the stomach antrum, and occasionally in the pancreas.
The vagus nerve innervates the<unk> s.<unk> astrin-releasing peptide is released by the post-ganglionic fibers of the vagus nerve onto<unk> s during parasympathetic stimulation.<unk> astrin-releasing peptide, as well as the presence of amino acids in the stomach, stimulate the release of<unk> astrin from the<unk> s.  <unk> astrin stimulates enterochromaffin cells to release histamine.<unk> astrin also targets parietal cells.
The increase of histamine and the direct stimulation by<unk> astrin, cause parietal cells to increase HCl secretion in the stomach.
