2

parts of oseophagus

1. cervical 2.thoracic 3. abdominal

3

Contrictions of oseophagus

cricopharyngeas, aortic arch, left main bronchus, opening of diaphragm

4

contrictions.. cricopharyngeus how many cm from incisor?

15 cm

5

contrictions.. aortic arch how many cm from incisor?

25cm

6

contrictions.. left main bronchus how many cm from incisor?

27cm

7

contrictions.. opening of diaphragm how many cm from incisor?

40cm

8

contrictions.. 15 cm from incisor?

cricopharyngeus muscle

9

contrictions.. 25 cm from incisor?

aortic arch

10

contrictions.. 27 cm from incisor?

left main bronchus

11

contrictions.. 40 cm from incisor?

opening of diaphragm

12

bifurcation of trachea at?

t4

13

beginning and relations of cervical esophagus

starts at the level of cricoid cartilage c6.... anterior: trachea and recurrent laryngeal n... posterior.. vertebra and ant longitudinal ligament

14

where does cervicle oseophagus lies?

lies in front of prevertebral fascia slighty to the left behind trachea

15

anterior relations of thoracic esophagus

trachea, left main bronchus, pericardium, left atrium, and right pulmonary artery

16

right and left relations of thoracic esophagus

arch and vagus.... left: arch of aorta , left vagus, lung and pleura... right:arch of azygos vein, right vagus, lung and pleura

17

end of thoracic oseophagus

by piercing diaphragm 1 inch to the left of midline opposit body of t10 or 7th left costal cartilage

18

which stuctures passes through the esophygeal opening of diaphragm? normally and pathologically

normally.. esophagus and vagus nerve.. pathologically hiatus hernia and osophageal varices

19

posterior relations of thoracic esophagus

vertebra and ant longitudinal ligament

20

surgical importance of contrictions

they are the sites of foreign body impaction

21

surgical importance of thoracic osophagus

mediastinal relations.. behind pericardial sac so used in transesophygeal echo can assess severity of left atrial enlargement

22

abdominal esophagus beginning

the end of thoracic osophagus.. 1 inch left to midline opposit the body of t10 or 7ths left costal cartilage

23

length of abdominal esophagus

4 to 5 cm

24

end of abdominal esophagus

at the gastro esophygeal junction

25

end of abdominal esophagus

at the gastro esophygeal junction

26

level of gastro esophygeal junction

t10

27

peritoneal covering of abdominal esophagus

only anteriorly
