Anatomy Of Stomach Flashcards
Anatomical Position
Lies within superior aspect of the abdomen between
esophagus and duodenum
Stomach spans the region between the
cardiac and pyloric
orifices of GIT
Empty stomach is most commonly —-shaped
J-
Stomach with moderate gastric contents occupies
epigastric,
left hypochondriac and
umbilical regions.
the exact size, shape and position of the stomach
can vary from person to person and with
position and
respiration
Numerous factors influence both the form and the position
of the stomach, including the
- Posture and build of the individual
- Extent to which the stomach is filled
- Position of the surrounding viscera
- Tone of the abdominal wall and
- Gastric musculature
Stomach types
- Sthenic (Normal)
- Hypersthenic (hypertonic) oblique
- Hyposthenic (hypotonic)vertical
- asthenic/atonic
Hypersthenic (hypertonic) seen in
obese persons
Hypersthenic (hypertonic)
Prone to
duodenal ulcers
Hyposthenic (hypotonic) prone to
gastric ulcers

Cardiac part
Fundus Is dome-shaped and projects superior and to the left of oesophageal
opening and cardia
Fundus lies in contact with
Left dome of diaphragm
Fundus lie above a horizontal line from
?to?
the cardiac notch to the greater curvature
Fundus often filled with
Gas (looked dark on X-ray )
