Q

4 steps to partitioning the mediastinum

A
  1. Heart and diaphragm develop in the neck region
    1. Body wall expands faster than the lungs are growing, Creates more space for lungs to grow into
    2. Diaphragm migrates, Innervated by phrenic nerve (C3-5)
    3. Phrenic nerves: Stay around ~width of the vertebrae, Creates a bend in the thoracic coelom, Creates a pleura and pericardial areas

Q

Each cavity and the organs within are lined with

A

mesothelium

21
Q

§ Mesothelium

A

□ Serous secreting epithelium (lining) that reduces friction
□ Mesodermal in origin
Entails the purpose of all body cavity linings

22
Q

what is the mediastinum

A

the area between the lungs

23
Q

sternal angle

A

angle created at the interface between the manubrium and the sternal body

24
Q

rib connecting to sternal angle

A

second rib

25
Q

rib 2 connects to

A

2nd thoracic vertebrae

26
Q

cupola

A

part of the mediastinum that protrudes above the superior thoracic opening

27
Q

transverse line from rib 2/sternal angle to T4/5

A

separates superior mediastinum from the other 3 parts

28
Q

middle mediastinum holds

A

pericardial contents

29
Q

anterior mediastinum located

A

below sternal angle and in front of the middle mediastinum/pericardium

30
Q

posterior mediastinum located

A
  • Below sternal angle and posterior to the pericardium
31
Q

lobes of lungs

A
  • Right has 3 lobes, left has 2
32
Q

lung lobes defined by

A

fissures

33
Q

lung fissures

A
  • Right has 2 fissures (horizontal and oblique), left has 1 (oblique)
34
Q

visceral layer of the pericardium

A

attached to the heart and vessels

35
Q

visceral layer of the pluera

A

attached to the lungs

36
Q

parietal layer of the pericardium

A

attached to the vertebrae, sternum, diaphragm, pleura

37
Q

parietal layer of the pleura

A

attached to chest wall, pericardium, diaphragm

38
Q

3 major structures passing through the diaphragm

A

inferior vena cava (IVC)
oesophagus
aorta

39
Q

auricles face

A

anteriorly

40
Q

apex of the heart points

A

anteriorly and to the left

41
Q

Chordae tendinae

A

prevent the valve from prolapsing

42
Q
  • Valves between ventricle and great arteries
A

Not at risk of prolapse - less pressure

43
Q

why ha left heart got thicker muscle

A
  • Left has to pump against pressure of all of the blood in the whole systemic circuit, needs more muscle
44
Q

vagus nerve

A
  • Autonomic nerve
    - Recurrent laryngeal branch
    - Left recurs around aortic arch
45
Q

vasa vasorum

A

capillary beds all over it - usually arteries

46
Q

connective tissue around arteries

A

usually circumferential

47
Q

vein connective tissue

A

randomised

48
Q

nerve connective tissue

A

longitudinal
