between the internal intercostal and innermost intercostal muscles

10
Q

What is the order of the neuromuscular bundle (NMB)?

VAN: Vein - Artery - Nerve

11
Q

Which rib is “privileged”?

A

rib 2 because it is longer and thinner than rib one and is attached at two points

12
Q

Where do common rib fractures occur?

A

the middle of the ribs along the posterior angle (ribs 3-10)

13
Q

What is Flail Chest?

A

If a rib is broken and loses attachment to the structures that contain it in the thoracic cage

14
Q

What movement is associated with Flail Chest?

A

paradoxical movement

15
Q

What is paradoxical movement?

A

the segment around the broken rib looks as if it is moving in the opposite direction of the breath motions.

16
Q

What else can paradoxical movement lead to?

A

hypoventilation due to insufficient ventilation

17
Q

What are the 3 major dermatomes?

A

T4 - Nipples (MOST IMPORTANT FOR NWOSU)

T7 - Xiphoid Process

T10 - Umbilicus

18
Q

What is Herpes Zoster’s precursor?

Chicken pox (Varicella)

19
Q

Where are Herpes Zoster infections commonly latent?

A

Dorsal root ganglia of one spinal level

20
Q

What happens when the Herpes Zoster virus leaves latency?

A

the area that is serviced by that sensory root (dermatome) receieve a pattern of blistered lesions

21
Q

What term is used to describe the blistered lesions of Herpes Zoster?

A

herpetic

22
Q

What are the important levels of the Sternum that we should consider?

A

Manubrium, sternal body, and xiphoid process

23
Q

Where is the manubrium found?

A

T3/4

24
Q

Where is the sternal body found?

A

T5-9

25
Q

Where is the xiphoid process found?

A

T10/11

26
Q

A Sternal puncture is commonly performed to obtain what?

A

bone marrow

27
Q

Where are sternal fractures common?

A

Mid body and transverse ridge fractures followed by the manubrium

28
Q

Where are fractures commonly incorrectly predicted?

A

xiphoid process

29
Q

What two notches are visible on the manubrium?

A

clavicular notches on the sides and the jugular notch in the middle

30
Q

What is another name for the sternal angle?

A

manubriosternal joint

31
Q

What is Thoracic outlet syndrome?

A

compression of the neuromuscular structures contained in the thoracic outlet

32
Q

What are the causes of Thoracic outlet syndrome?

A

cervical rib, hypertrophy of Scalene Muscles, or a Pancoast Tumor

33
Q

What are the symptoms associated with Thoracic outlet syndrome?

A

pain, numbness, tingling in the arms. brachial plexus compression. Ischemic muscle pain. Subclavian artery compression

34
Q

Describe Horner’s Syndrome

A

Psuedo-ptosis - droopy eyelids

Anhydrosis - can’t sweat

Miosis - pupil constiction

PAM IS HORNY!

35
Q

What is the cause of Horner’s syndrome?

A

compression of the Stellate

36
Q

What is the Stellate?

A

Superior cervical ganglion - is compressed causing Horner’s

37
Q

What is the Thoracic Diaphragm?

A

a musculo-tendinous partition that is the principle muscle of inspiration

38
Q

How is the Thoracic diaphragm innervated?

A

Phrenic nerve C3-4

39
