what parts of the body drain into the right (minor) lymphatic duct
- right upper extremity
- right hemicranium
- the heart
- lung except left upper lobe
Describe the course of the thoracic duct
- traverses sibson’s fascia of the thoracic inlet up to levels of C7 before turning around and emptying into the left (major) duct
- extends approximately 18 inches from the cisterna chyli below the diaphragm (at the level of L2), through the aortic hiatus (at the level of T12) into the neck for about 3 cm before draining into the left major duct
The sympathetic control to the lymphatic duct is topographically innervated by what nerves
intercostal
The cisterna chyli is innervated by what nerve
T11
The lymphatics relieve the body’s excess fluids and wastes by both intrinsic and extrinsic forces. What are the extrinsic?
- OMM
- exercise
- contraction of muscles
- Pulsation of adjacent arteries
- Respiratory movement to increase negative intrathoracic pressure
The lymphatics relieve the body’s excess fluids and wastes by both intrinsic and extrinsic forces. what are the intrinsic?
- smooth muscle contraction
- interstitial fluid pressure
What are the factors that increase interstitial pressure and therefore allow extracellular fluid to enter the lymphatics
- Systemic HTN
- cirrhosis (dereased plasma protein synthesis
- Hypoalbuminemia associated with starvation
- Toxins such as rattlesnake poisoning
Where are the places on the body most commonly affected by lymphatic dysfunction
- supraclavicular
- posterior axillary fold
- epigastric area
- inguinal
- popliteal
- Achilles tendon
What are the relative contraindications to lymphatic treatment
- Osseous fractures
- Bacterial infections with a temperature greater than 102F
- Abscess or localized infection
- Certain stages of carcinoma
