Q

Contents of Aortic Hiatus

A

Aorta, Thoracic Duct, Azygous Vein

23
Q

Impact of Contraction of Diaphgram on Vena Cava Aorta and Esophagus

A

Esophagus contract: prevents stomach contents from going into esophagus
Vena Cava: Dilates increases blood Flow
Aorta: No impact on it because it doesnt pass diaphgram

24
Q

Condition where esophagus isn’t able to keep stomach contents from going into thorax

A

Hiatal Hernia

25
Q

Pericardiophrenic Aretery

A

Comes from Internal Thoracic Artery, runs alongside Phrenic Nerve. Supplies Pericardium and Diaphgram

26
Q

Musculophrenic Artery

A

Branches of Internal Thoracic artery and gives some blood to diaphgram

27
Q

Superior Phrenic artery

A

Comes off the aorta and supply superior part of diaphgram

28
Q

Inferior Phrenic Artery

A

Once aorta goes behind diaphgram it gives off inferior phrenic. It supplies the inferior diaphgram

29
Q

Motor Innervation of Diaphgram

A

C3 C4 C5 keeps you alive

30
Q

Sensory of Diaphgram

A

Phrenic Nerve: Central Portion

Intertcostal Nerves T7-T 12: Peripheral parts

31
Q

Autonomic Innervation Overrides what?

A

Somatic Innervation

32
Q

Fusion of four structures that form the diaphgram

A

Septum transversum , Dorsal Esophgeal mesentry, peripheral rim of body wall, Pleruperitoneal membranes

33
Q

Septum Transversum origination

A

Mesoderm that originally develops from cervical myotomes and then migrates caudally. It is innervated by Cervical Spinal Cord Segments

34
Q

Herniea caused by congenital Abnormalities of diaphgram

A

Foramen of morgani, Foramen of Bochdalek, Central Tendon Deficiency and large esophgeal hiatus

35
Q

Acquired Herniae

A

Sliding: Upper stomach and lower esophagus slide upwards together when patient bends or lies down
Rolling: Cardia remains in normal position and fundus rolls upwards. (no regurgitation)

36
Q

What lies in the Fatty tissue of breast

A

15-20 lobes of grandular tissue

37
Q

Where are mammary glands drained?

A

At nipple by lactiferous ducts

38
Q

Pigment around nipple

A

Areola

39
Q

What happens to Lobules during lactation

A

Smaller

40
Q

What supports the lobules

A

Connective tissue suspensory ligaments

41
Q

Space between breast tissue and pectoral Fascia

A

Retromammary Space

42
Q

Scrinched Skin around lymphatic system infected. Builds up in dermis around hair follicle

A

Peau d’ Orange

43
Q

What fills up during cancer and causes assymetery as breast moves up and down pectoral wall

A

Retromammary Space

44
Q

What is important part of breast tissue, not normally thought of as part of breast

A

Axillary Tail

45
Q

Arterial supply to breast is via mammary branches of

A

Internal Thoracic, Lateral Thoracic, Thoracoacromial and posterior intercostal arteries (this branches from thoracic aorta)

46
Q

Venous drainage occurs via tributaries to

A

Axillary Vein and internal thoracic vein

47
Q

Why is lymphatic drainage important?

A

Due to its roll in breast cancer

48
Q

Apporximately 75% of lymphatic drainage occurs to

A

Lateral, subscapular, central, pectoral and apical Lymph nodes

49
Q

Axillary nodes not usually involved in breast ancer

A

Lateral and Subscapular

50
Q

Nodes involved in cancer

A

Apical Pectoral Central

51
Q

25% drainage goes to

A

infraclavicular, supraclavicular and parasternal Nodes

52
Q

Interpectoral Node

A

Between pec major and minor. Dangerous to drain here

53
Q

Positive cancer biopsy of this node indicated cancer probably spread to blood

A

Scalene Node Cancer in supraclavicular area

54
Q

Path of Lymph

A

Pectoral to central to apical
