Lecture 1 (Feb 12) Flashcards
List the branches of the celiac trunk
- Left gastric artery
- Splenic artery
- Common hepatic artery
The left gastroepiploic artery is branch of which artery?
Splenic artery
The right gastroepiploic artery is a branch of which artery?
Gastroduodenal artery
Where does the esophagus enter the diaphragm and at which vertebral level?
The esophagus enters the diaphragm through the esophageal hiatus and at T-10 level
What type of muscle is found in the first, middle and last thirds of the esophagus?
1) First third - voluntary striated muscle
2) Middle third - both voluntary and smooth muscle
3) Last third - smooth muscle
Which arteries provide arterial supply to the esophagus?
- The esophageal branches of the left gastric artery (branch of celiac trunk)
- The left inferior phrenic artery
Which lymphatic trunks and nodes does the thoracic part of the esophagus drain into?
1) Upper - Jugular trunks
2) Middle - Bronchomediastinal trunks
3) Lower - Superior diaphragmatic nodes
Which lymph nodes does the abdominal part of the esophagus drain into?
Celiac (abdominal) nodes
What forms the physiological inferior esophageal sphincter?
Diaphragmatic musculature that surrounds the hiatus
What does the Z-line demarcate?
Demarcates the transition from the esophageal to the gastric mucosa
What are the two parts of the pyloris? Which part is wide and which part is narrow?
- Antrum (wide)
- Canal (narrow)
Along which curvature is the angular incisure found?
Less curvature
The angular incisures is the junction between which structures?
Body and pylorus
When and where does the gastric canal form?
- When = During swallowing
- Where = Forms between the longitudinal gastric curves along the less curvature
Which arteries supply the lesser curvature, and which supply the greater curvature?
- Lesser = Anastomoses of the left and right gastric arteries
- Greater = Anastomoses of the left and right gastro-omental artery
