Review
Here is what we have learned from this unit:
- There are two different subsite descriptions for the esophagus:
- Subsite description 1 divides the esophagus into three segments
or regions: cervical, thoracic, and abdominal.
- Subsite description 2 divides the esophagus into three portions:
the upper third, middle third, and lower third.
- The stomach lies just below the diaphragm in the upper part of the
abdominal cavity primarily to the left of the midline under a portion
of the liver, and its main divisions are the cardia, the fundus, the
body, and the pyloric antrum.
- The small intestine is a tube measuring about 2.5 cm in diameter and
over 600 cm (20 feet) in length, and it has three divisions: duodenum,
jejunum, and ileum.
- Small aggregates of lymphoid tissue called Peyer patches are found
in the lamina propria of the small intestine, mainly in the distal ileum.
- The esophageal wall contains four layers: mucosa, submucosa, muscularis,
adventitia.
- Layers of the stomach wall, among others, include serosa, muscularis,
submucosa, mucosa.
- The three layers of smooth muscle consists of the outer longitudinal,
the middle circular, and the inner oblique muscles.
- Esophageal lymph nodes include cervical, upper and middle thoracic,
and lower thoracic lymph nodes.
- Regional lymph nodes of the stomach include inferior (right) gastric,
splenic, superior (left) gastric, perigastric, celiac, and hepatic lymph
nodes.
- Hepatic, superior mesenteric, and posterior cecal and ileocolic nodes
are regional lymph nodes for small intestine.
