During swallowing, food passes from the mouth through the pharynx into the esophagus and travels via peristalsis to the stomach. Stomach - correct answer Dilated, saclike portion of the digestive tract extending between the esophagus and the small intestines. cardia, fundus, body, pyloric portion - correct answer 4 main parts of Stomach Cardia - correct answer section immediately surrounding the esophageal opening. Fundus - correct answer superior portion of the stomach that expands superiorly and fills the dome of the left hemidiaphragm gastric bubble/magenblase - correct answer When patient is upright, this portion is filled up by gas and is referred to the Body - correct answer begins at the level of the cardiac notch (incisura) and ends at the plane passing through the angular notch (incisura angularis- indentation along the lesser curvature) and the sulcus intermedius (indentation along the greater curvature). Pyloric portion/antrum - correct answer the distal end of the stomach seen to the immediate right of the angular notch and connects with the pyloric canal esophagogastric junction (cardiac orifice), Pyloric orifice (pylorus) - correct answer Two openings of the stomach Esophagogastric junction (cardiac orifice) - correct answer is the aperture, or opening, between the esophagus and the stomach Pyloric orifice (pylorus) - correct answer The orifice, or opening between the stomach and small intestines Cardiac notch (incisura cardiaca), Cardiac antrum, Lesser curvature, Greater curvature - correct answer STOMACH CURVATURES Cardiac notch (incisura cardiaca) - correct answer Directly superior to this orifice is a notch called the cardiac notch (incisura cardiaca) Cardiac antrum - correct answer distal abdominal portion of the esophagus curves sharply into a slightly expanded portion of the terminal esophagus Lesser curvature - correct answer which is found along the medial border of the stomach, forms a concave border as it extends between the cardiac and pyloric orifices Greater curvature - correct answer is found along the lateral border of the stomach. This greater curvature is four to five times longer than the lesser curvature serous (outermost layer), muscular (inner circular and outer, submucous, mucous (innermost layer which is opacified by contrast medium) - correct answer The wall of the stomach is composed of four layers Rugae - correct answer When the stomach is empty, the internal lining is thrown into numerous longitudinal mucosal folds Rugae - correct answer MUCOSAL FOLDS WITHIN THE STOMACH Fundus - correct answer the most superior portion of the stomach in general, is located posterior to the body of the stomach, Body - correct answer inferior and anterior from the fundus. Pylorus - correct answer directed posteriorly Hypersthenic (massive) Sthenic (average) HypoSthenic (slender) Asthenic (very slender) - correct answer 4 types of body habitus hypersthenic - correct answer 5.0% ◼ - massive body build Sthenic - correct answer 50.0% - Moderately heavy sthenic - correct answer ∙ StomachT10-L2. ∙ Pyloric portion level of L2 near midline. ∙ Duodenal bulb L2 near midline. hyposthenic - correct answer 35.0%▪ Lies between sthenic and asthenic asthenic - correct answer 10.0% ◼ extremely slender build HYPOSTHENIC,ASTHENIC - correct answer - J-shaped stomach, low and vertical, T11-L4. - Pyloric portion level of L3- L4 to left of midline. - Duodenal bulb at the level of L3-L4. steer horn - correct answer found in individual that is short & stocky (overweight) steer horn - correct answer The Stomach is - high - extends more towards left - horizontal position - incisura angularis above level of pylorus 1cm - occasionally pylorus is the lowermost part of the stomach Eutonic - correct answer - found in asthenic individual - stomach - J-shaped- body tends to be vertical in AP projection & uniform in size hypotonic - correct answer - found in asthenic individuals (underweight)
