25
Regeneration possible when
20% of node remains intact (hilum preserved)
26
Thoracic duct drains
Left head, neck, chest, arm; abdomen; both legs
27
Right lymphatic duct drains
Right head, neck, chest, arm; right lung (all lobes); lower left lung; part of liver
28
Starling equation
EF + ER + ELOL = Balance
29
Effective Filtration (EF)
Fluid moving OUT of blood capillary into tissues
30
Effective Resorption (ER)
Fluid moving FROM tissues back into blood capillary
31
Lymph Obligatory Load (LOL)
Waste/protein/fluid that must be removed by lymphatics
32
Forces affecting filtration
Blood pressure + oncotic tissue pressure
33
Forces affecting resorption
Tissue pressure + oncotic blood pressure
34
Components of LCT
Collagen, elastin, reticular fibers, fibroblasts, lymphocytes, macrophages, adipocytes, ground substance
35
Ground substance contains
Water, HA, salts, lipids, mucopolysaccharides
36
Functions of LCT
Transport, defense, repair, fluid reservoir, nutrient delivery
37
Transit Stretch
Distance between capillary and cells (MLD improves this)
38
Thixotropy
Gel ↔ sol transformation with movement
39
Hysteresis
Tissue does not immediately return to original shape
40
MLD: Sympathicolytic effect
Reduces sympathetic output; increases parasympathetic activity (deep relaxation)
41
MLD: Analgesic effect
Mechanoreceptors override nociceptors → pain reduction
42
MLD: Immune effect
Increases lymphocyte activation and waste removal
43
MLD: Drainage effect
Moves lymph load, reduces swelling and inflammation
44
How MLD aids nervous system
Activates PSNS, calms SNS, improves sleep and healing
45
How MLD reduces pain
Stimulates mechanoreceptors → blocks pain signaling
46
Connective tissue response to movement
Becomes more fluid (thixotropic), improving lymph transport
47
Absolute CI
Acute infection, untreated cancer, thrombosis, congestive heart failure
48
Relative CI
Hyperactive thyroid, chronic inflammation, menstruation, naevi, eczema flare
49
MLD for acne
Reduces inflammation; avoid active lesions
50
MLD for cystic acne
Treat like other acne but avoid direct stimulation
51
MLD for rosacea
Extremely light pressure; reduces heat and redness
52
MLD for puffy eyes
Drain medial → lateral → terminus
53
MLD for eczema
Treat only in non-flare periods
54
MLD for aging skin
Boosts oxygen/nutrient delivery; improves sagging
55
Blepharoplasty MLD rule
Avoid incisions; extremely light drainage to neck
56
Rhinoplasty MLD rule
No direct nasal pressure; drain lateral → neck
57
Facelift MLD rule
Avoid incisions; gentle drainage from face → neck
58
When to treat hematomas
Only after stabilization (usually 3–4 days post-injury)
59
Brain drainage facts
No true lymph vessels inside CNS; drainage via CSF + perivascular spaces
60
40% drainage pathway
Cranial nerves (olfactory, optic, auditory)
61
60% drainage pathway
Epidural lymphatics + spinal nerves
62
Area
ILVs draining to one pre-collector
63
Zone
Areas draining to one collector
64
Territory
Zones draining to regional lymph nodes
65
Mnemonic for hierarchy
A → Z → T (Area → Zone → Territory)
66
Basic MLD stroke
Stationary circle
67
Stationary circle steps
Lengthwise stretch → directional stretch → zero phase
68
Zero phase
Skin returns to original position with no assistance
69
Pressure used in MLD
VERY light (~35 mm torr)
70
Golden rule of MLD
Light, slow, proximal to distal, no sliding, no hyperemia
71
Lymph Time Volume
Amount transported per time unit
72
Transport Capacity (TC)
Max amount lymph system can carry
73
Functional Reserve
TC – LOL
74
What reduces TC
Surgical trauma, inflammation, fibrosis
75
Major components of lymph
Water, proteins, fats, dead cells
76
Minor components
Pathogens, dyes, debris
77
How proteins return to blood
Via lymphatic system
78
Lymph nodes draining eyes
Preauricular, parotid, submandibular
79
Drainage of eyelids
Medial → lateral → preauricular/parotid
80
Inner eye corner movement
Begin lateral → medial
81
4 effects of MLD
Sympathicolytic, analgesic, drainage, immune
82
Term for water moving out of capillaries
Filtration
83
Term for water moving into blood capillary
Resorption
84
Where lymph from head/neck drains
Terminus (left or right)
85
What induces MLD rhythm?
Parasympathetic activation
