A

Tracheobronchial Nodes

10
Q

Three constrictions of the esophagus

A
  1. Where it begins,
  2. where it is crossed by the left main bronchus and aortic arch on anterior surface
  3. where it pierces the diaphragm
11

A

Vein
Artery
Nerve

12

Lower border of the lungs and pleura

A

Lungs Pleura
6th rib 8th midclavicular
8th rib 10th midaxillary
10th rib 12th side of vertebral column

13
Q

Anterior and posterior border of pericardium

A

Anterior - 2nd to 6th costal cartilage

Posterior - 5th to 8th thoracic vertebrae

14
Q

Part of pericardium attached to sternum, great blood vessels, and diaphragm

A

Fibrous pericardium

15
Q

This is divided into parietal and visceral pericardium

A

Serous pericardium

16
Q

Normal volume of pericardial fluid

A

50 mL

17
Q

Nerve supply of the pericardium

A

Fibrous + Parietal Serous - phrenic nerve

Visceral Serous - Sympathetic trunk and vagus

18
Q

A

Phrenic Nerve (C3-C5)

19
Q

Inferior thyroid artery

Internal throracic artery

20
Q

Location of thymus in the mediastinum

A

Superior Mediastinum. Sometimes anterior

21
Q

Contents of the posterior mediastinum

A

Esophagus, thoracic duct, sympathetic trunks

22
Q

Small accessory muscles of inspiration found at the back of the chest wall

A

Levator Costarum

23
Q

Differentiate the main bronchi (width, length, and verticalness)

A

Right is wider, shorter, and more vertical

Left is narrower, longer, and more horizontal

24
Q

Which main bronchi gives off the superior lobar bronchus before entering the hilum?

A

Right

25
Q

Which main bronchus passes below the arch of the aorta and in front of the esophagus?

A

Left

26

Q

Landmark for doing pericardiocentesis, and why?

A

Left ofxiphoid process (Left subcostal angle)

Cardiac notch is here, so no pleura and lung
