Q

True or False. The clavicle forms the posterior border of the lateral cervical triangle.

25
Q

True or False. The upper trapezius forms the inferior border of the lateral cervical triangle.

26
Q

True or False. The three chains of the lateral cervical triangle drain into the left or right venous angle.

27
Q

True or False. It is find to work the lateral territory on the upper arm area that is swollen due to removal of axillary lymph nodes because the lymph collectors also drain into the supraclavicular lymph nodes.

28
Q

True or False. The collectors of the ventromedial bundle form a bottleneck behind the medial femoral condyle/medial aspect of the knee.

29
Q

True or False. 75% of the lymph from the mammary gland drains into the parasternal lymph odes, and 25% drains into the axillary lymph nodes.

30
Q

True or False. Before working on the swollen upper extremity, we need to decongest the trunk on the ipsilateral side.

31
Q

True or False. External genitalia drain into the inguinal lymph nodes, and the internal reproductive organs drain into the pelvic lymph nodes.

32
Q

True or False. Proteins are macromolecules and hydrophilic.

33
Q

True or False. There are usually 300-450 grams of protein in the blood, at any given time.

34
Q

True or False. Lymphedema usually manifests more in the deep lymphatic system.

35
Q

True or False. The type of stimulation that activates contraction of the smooth muscles in the lymph collectors is a smooth, slow stretch.

36
Q

True or False. The thoracic duct originates at the cisterna chyli.

37
Q

What is edema?

A

An accumulation of water in the tissues.

38
Q

What are some common conditions that cause edema?

A
  • heart conditions
  • pregnancy
  • venous insufficiencies
39
Q

What is the most common cause of lymphedema in the US?

A

breast cancer surgery

40
Q

What is the most common cause of lymphedema in the world?

A

filiariasis

41
Q

What are the four main components of lymphatic load (LL)?

A
  • water
  • proteins
  • cells/cell fragments
  • long-chain fatty acids
42
Q

What represents the beginning of the lymphatic system?

A

lymph capillaries

43
Q

What percentage of water is reabsorbed from the interstitial tissues back into the blood capillaries, in a healthy body?

44
Q

What percentage of water remains in the interstitial spaces (is not reabsorbed) and becomes lymphatic load of water?

45
Q

How much lymph fluid is normally returned to the venous system in 24 hours?

A

2-4 liters

46
Q

What percentage of the total circulating blood proteins leave the capillaries and move into the interstitial space in 24 hours?

47
Q

Where do proteins end up after leaving the blood capillaries?

A

interstitial space

48
Q

How do proteins get back into the blood?

A

through the lymphatic system

49
Q

What lymphatic structures filter lymph fluid?

A

lymph nodes

50
Q

Where does the fat portion of the LL come from?

A

chylous vessels of the small intestine

51
Q

Which structures comprise the superficial lymphatic system?

A
  • initial lymph capillaries
  • pre-collectors
  • lymph collectors
52
Q

Where is the deep lymphatic system located?

A

beneath the fascia

53
Q

What is the purpose of the deep lymphatic system?

A
  • drains the muscles and tendons
  • drains the joints
  • drains the inner organs
54
Q

Which structures first pick up the LL and thus, begin the lymphatic system?

A

initial lymph capillaries

55
Q

What is the purpose of the initial lymph capillary?

A

lymph formation

56
Q

What is the purpose of lymph pre-collectors?

A

connect superficial capillaries to superficial collectors

57
Q

Where are the superficial collectors located?

A

in the superficial fatty tissue, above the fascia

58
Q

What is the purpose of collectors?

A

transport lymph to lymph nodes and lymphatic trunks

59
Q

What do perforating pre-collectors do?

A

connect the superficial and deep lymphatic system
